What is  emission spectrum?

Emission spectrum is defined as a spectrum of a chemical compound or substance composed of frequencies of electromagnetic radiation. Radiations which are emitted while electron make transition from higher to lower energy level.

Energy of photon is equal to the difference between the two energy states . There are many possible electronic transitions in an atom and every transition has a specific wavelength.

Collection of different transitions with respect to different wavelengths makes up an emission spectrum.Emission spectrum of each element is unique and therefore spectroscopy is used to identify elements which are present in different substances.

how to determine whether a liquid is pure water or not besides boiling the liquid?

Answers

Answer:

Explanation:

Aside the boiling point of water, another colligative property that can be used to identify pure water (or not) is the freezing point. Water freezes at 0 °C, but with the presence of impurities, there is a freezing point depression of the water. Thus, if the water is not pure, the liquid could freeze at a temperature lower than 0 °C (with a negative sign like -8 °C).

Which is the IUPAC name for NO?

Answers

Answer:

Nitrogen (ii) oxide

Explanation:

To know the IUPAC name for NO, we shall determine the oxidation number of N in NO.

NOTE: The oxidation number of oxygen (O) is always – 2.

Thus the oxidation number of N in NO can be obtained as follow:

N + O = 0 (ground state)

N + (– 2) = 0

N – 2 = 0

Collect like terms

N = 0 + 2

N = +2

Thus, the oxidation number of Nitrogen (N) in NO is +2.

Therefore, the IUPAC name for NO is Nitrogen (ii) oxide

A scientist built a computational model to investigate what happens when magma comes into contact with the ground surface. In the model, the ground surface was 293K, whereas the magma was 1,500K. The model examined different depths of the magma away from Earth's surface and toward the core. Over a greater amount of time, more magma cooled. What form of heat transfer accounts for the magma cooling? ​​​​​​​

Answers

Answer:

Conductive heat transfer is most likely responsible for the cooling of the magma

Explanation:

The Earth's core is continuously cooling due to human's digging, allowing for more space and heat escape from the Earth's core. All magma closer to the core would have its heat absorbed by the core, hereby increasing its coolness.

This heat transfer process is common to conduction.

when elements from C bond with elements from D

when elements from A bond with themselves

Answers

Answer:

when elements from A bond with elements from B

Explanation:

The elements in part A are metals and that of B are non-metals. Ionic bonds are formed between metals and non-metals. Thus option b is correct.

What is ionic bonding?

An ionic bond is  formed between a metal and non-metal through loss of electron from the metal to the non-metal. Metals are electron rich and easily loss electrons.

Non-metals are electronegative and they are electron -deficient. They need to gain electrons to attain stability. Therefore non-metals such as oxygen, nitrogen, carbon etc. bonds with metals by gaining electrons from metals.

The positive charge of metal acquired by loss of electron and negative charge of nonmetals acquired by gain of electron attracts electrostatically and form the ionic bond.

The elements from A thus bonds ionically with elements from B.

Can you tell from the masses of the reactants which one of the reactants will be the limiting reactant? Defend your answer (use an equation within your defense).

Answers

Answer:

Explanation:

so, limiting reactants are the reactant which limit the continuing of the reaction or in simple word they are the element that run out first and are totally consumed

equation :

2koh+h2so4⇒ k2so4 +2h2o

if we have 4 mol of h2so4 and 3 mol of 2koh

                 number of produced moles of k2so4 on consuming all :

h2so4 ⇒ k2so4

1 mol          1 mol

4 mol            ?mol

no of mol of k2so4 if all h2so4 is consumed 4 mol

2koh⇒ k2so4

2 mol       1 mol

3 mol         ?mol

no of mol of k2so4 if we consume all koh = 1.5 mol

since the koh produces less mol on consuming it all

the koh is the limiting reactant

Answers

Answer:

electrons

Explanation:

since they are at the outer part of nucleus

Answer:

Weakly

Explanation:

Being farther from the nucleus and with more electrons shielding the protons results in the valence electrons being held weakly.

The effect of the nuclear pull will not be felt so strongly by the valence electrons. The valence electrons are the outermost electrons that occupies a shell. When the inner orbital electrons are much and the atomic radius is large, the valence electrons are well shielded. This results in electropositivity and a low ionization energy.

Aqueous solutions of sodium carbonate and magnesium chlorate are mixed, what is the precipitate, chemical equation, complete ionic equation, and net ionic equation

Answers

Answer:

Explanation:

Na₂CO₃ (aq)+ MgCl₂ (aq) =  MgCO₃(s)  +2NaCl (aq)

MgCO₃(s) is the precipitate .

Ionic equation

2 Na⁺¹ + CO₃⁻² + Mg⁺² + 2 Cl⁻¹ = MgCO₃(s) +2 Na⁺ + 2 Cl⁻

net ionic equation

Mg⁺² + CO₃⁻² = MgCO₃ (s) .

The precipitate formed in the reaction has been the magnesium carbonate salt.  The net ionic equation will be: [tex]\rm Mg^2^+\;+\;CO_3^2^-\;\rightarrow\;MgCO_3[/tex].

The mixture of sodium carbonate and magnesium chlorate has been given as:

[tex]\rm Na_2CO_3\;+\;MgCl_2\;\rightarrow\;MgCO_3\;+\;NaCl[/tex]

The precipitate formed in the reaction has been the magnesium carbonate salt.

The chemical equation has been written as the equation with the states of the reactants and the products.

[tex]\rm Na_2CO_3\;(aq)\;+\;MgCl_2\;(aq)\;\rightarrow\;MgCO_3\;(s)\;+\;2\;NaCl\;(aq)[/tex]

The ionic equation for the reaction has been:

[tex]\rm Na_2CO_3\;\rightarrow\;2\;Na^+\;+\;CO_3^2^-[/tex]

[tex]\rm MgCl_2\;\rightarrow\;Mg^2^+\;+\;2\;Cl^-[/tex]

[tex]\rm MgCO_3\;\rightarrow\;Mg^2^+\;+\;CO_3^2^-[/tex]

[tex]\rm NaCl\;\rightarrow\;Na^+\;+\;Cl^-[/tex]

The ionic equation for the reaction will be:

[tex]\rm 2\;Na^+\;+\;CO_3^2^-\;+\;Mg^2^+\;+\;2\;Cl^-\;\rightarrow\;MgCO_3\;+\;2\;Na^+\;+\;2\;Cl^-[/tex]

The net ionic equation has been consisted of the products that have been different on both the product and the reactant side. The same ions are eliminated in the net ionic equation. The net ionic equation will be:

[tex]\rm Mg^2^+\;+\;CO_3^2^-\;\rightarrow\;MgCO_3[/tex]

true or false

Answers

Answer:

Solids - vibrational (and rotational); moving very slowly.

Liquids - vibrational, rotational, and translational; moving quickly.

Gases - vibrational, rotational, and translational; moving very quickly.

Explanation:

Particles are always moving. No matter what. There is a certain point where they move so slowly it is considered minuscule, but they are in fact moving.

Thus, in solids, liquids, and gases, you can expect particles to move in a certain trend. That trend is average kinetic energy of the particles and the forces holding them together (attraction).

Every Saturday morning for as long as I can remember I have seen him leave, always by himself, to look for treasure. I have always longed to go with him, and hes always told me that someday I would get the chance. I was so excited when he told me I would finally have my chance that I was bouncing off the walls like a rubber ball and springing from one place to the next the rest of the day.He has always been as quiet as a mouse about the treasure that he finds, scurrying away with his equipment in the morning and piling up his treasure in his study. Even though he says he always comes home with something, he has never shown it to me or even told me what type of treasure it is. Is it gold, or silver, or maybe its precious jewels? Whatever it is, tomorrow I will find out, and hopefully hell let me bring some to class so that I can show my friends since Ive been bragging about it to them ever since Dad told me I could go!Saturday, April 3The treasure hunt was fun, but it was not what I expected. Dad and I left early in the morning and headed for the same woods that we sometimes go hiking in on Sundays. I never would have thought they hold treasure, but what was really odd was when Dad told me to leave the shovels at home because we wouldnt need them. But what he did bring with him was a bright yellow GPS . I had seen it in his truck many times before. I always wondered what he did with it. Today I found out.Dad and I wandered into the woods, first staying on the hiking path I had taken several times before and then veering off the path. The forest was like a statue; it was still and covered in damp moss and dead leaves; it didn't even seem alive. It appeared that no one had been there for a long time so I knew that this treasure must be old and far under the ground. How were we going to get to it without shovels?As Dad kept his eyes on the GPS , I looked around, and suddenly I noticed a patch of leaves that was disturbed and a log that looked like it had been moved. When I asked Dad about it, his eyes lit up, and he said he saw the treasure. He reached under the log and pulled out a plastic box with a label that read Official Geocache.I didnt know what an official geocache was, but I soon found out when Dad opened it. Inside was a little notebook and a bunch of small items like a set of dice, a toy car, and a large silver dollar. Dad said that he thought the toy car was cool, so he took it out and put it in his pocket and then pulled a golf ball from his other pocket and put it in the box. He wrote his name and my name in the little notebook and then closed the box and put it back where he found it.Geocaching, which is what Dad later told me this type of treasure hunting is called, was much different than digging for gold in the ground. But I thought it was fun, and I hope Dad takes me again next Saturday.Part AIn "Nicholas's Diary: April 2 and 3," what is Nicholass first thought when he and his father leave home to go treasure hunting?It is not going to be the type of treasure hunt that he thought it would be.He will not be finding gold or silver, but something far more important.He will not have a very good story to tell his friends at practice on Monday.The treasure will be carefully hidden and closely guarded.Question 2Part BWhich sentence from the text best supports the answer in Part A?what was really odd was when Dad told me to leave the shovels at home because he said we wouldnt need them.As Dad kept his eyes on the GPS , I looked around, and suddenly I noticed a patch of leaves that was disturbed and a log that looked like it had been moved.Dad and I left early in the morning and headed for the same woods that we sometimes go hiking in on Sundays."The forest was like a statue; it was still and covered in damp moss and dead leaves; it didn't even seem alive."
