Determine the number of hydrogen atoms in an alkyne with one carbon–carbon triple bond and 4 carbon atoms.
number of hydrogen atoms: ?

Answers

Answer:

There are 6 hydrogen atoms.

Explanation:

The formula for an alkyne that has only one triple bond is as follows:

CₙH₂₍ₙ₎₋₂

Where n is any natural number greater than 2.

For this problem, n=4. This would mean the formula is:

C₄H₂₍₄₎₋₂

Thus

C₄H₈₋₂C₄H₆

Thus the answer is 6, there are 6 hydrogen atoms.

32. Calcium carbide, CaC2, is an important preliminary chemical for industries producing
synthetic fabrics and plastics. CaC2 may be produced by heating calcium oxide with
CaO + C CaC2+CO
What is the mass of CaC2 which can be produced from the reaction of excess calcium oxi
10.2 g of carbon? (Hint: Balance the equation first)​

Answers

Answer:

18.1 g

Explanation:

Step 1: Write the balanced equation

CaO + 3 C ⇒ CaC₂ + CO

Step 2: Calculate the moles corresponding to 10.2 g of C

The molar mass of C is 12.01 g/mol.

10.2 g × 1 mol/12.01 g = 0.849 mol

Step 3: Calculate the moles of CaC₂ produced from 0.849 moles of C

The molar ratio of C to CaC₂ is 3:1. The moles of CaC₂ produced are 1/3 × 0.849 mol = 0.283 mol

Step 4: Calculate the mass corresponding to 0.283 moles of CaC₂

The molar mass of CaC₂ is 64.10 g/mol.

0.283 mol × 64.10 g/mol = 18.1 g

What is the difference between a purine and a pyrimidine?

Answers

Answer: Adenine and guanine are the two purines and cytosine, thymine and uracil are the three pyrimidines. The main difference between purines and pyrimidines is that purines contain a sixmembered nitrogencontaining ring fused to an imidazole ring whereas pyrimidines contain only a sixmembered nitrogencontaining ring. They both are types or categories of nitrogen containing bases present in nuclei acids of DNA and RNA.

Purines are 2 Ring or Carbon Ring, Nitrogen containing bases. That consist of these 2 rings next placed next to each other. These examples include - Adenine and Guanine.

Pyrimidines are 1 or single Ring Nitrogen containing structures. There are 3 nitrogenous bases that are categorized as pyrimidines. Cytosine, Thymine, and Uracil.

living things are organic, so chemical is wrong, detrital is when rocks form from broken down rocks left behind, again not from living things so that's also wrong, that leave Organic and foliated, foliated makes no sense which leave only Organic, so organic will be your answer

Joshua wants to create something to put between a hot pot and a table, so he doesn't burn the table. He
knows he needs to choose a material that does not conduct heat well. Which material would be the best for
him to choose?
A. Wood
B. Aluminum
C. Copper
D. Glass

Answers

Copper is a good conductor of heat. This means that if you heat one end of a piece of copper, the other end will quickly reach the same temperature. Most metals are pretty good conductors; however, apart from silver, copper is the best.

Aluminum is an excellent heat and electricity conductor and in relation to its weight is almost twice as good a conductor as copper.

Glass is a very poor heat conductor. It has one of the lowest possible heat conduction a solid (without air trapped in it) can possibly have, this is mostly due to its lack of ordered crystal structure. Since it's an insulator, the electronic contribution to the thermal conductivity is very small.

Metals and stone are considered good conductors since they can speedily transfer heat, whereas materials like wood, paper, air, and cloth are poor conductors of heat. ... These include copper (92), iron (11), water (0.12), and wood (0.03).

Wood and Glass do not conduct heat well, aluminum is the best for him to choose because

aluminum conducted heat the fastest at an average of 14 seconds. ... Aluminum has the ability to absorb heat faster than copper, and when removed from the heat source, will cool faster because it is less dense than copper

The average speed of an oxygen molecule is 6.14 x 104 cm/sec at a certain temperature. What is the average speed of a CO2 molecule at the same temperature? (molar mass O2 = 31.9988; CO2 = 44.0098)

Answers

Answer:

the average speed of [tex]V_{av} CO_2[/tex] is 5.24 ×  104 cm/s

Explanation:

The computation of the average speed of a [tex]CO_2[/tex] is as follows:

[tex]\sqrt{average} = \sqrt{\frac{8 RT}{\pi M} }[/tex]

where,

M = Molar mass

[tex]V_{av} = \frac{\sqrt{1}}{M}[/tex]

Given that

[tex]V_{av} \ of\ oxygen= 6.14 \times 10^4 cm/s[/tex]

The molar mass of oxygen i.e. (MO_2) = 31.9988 g/mol

And, the molar mass of CO_2 is  44.0098 g/mol

Now

[tex]\frac{V_{av} CO_2}{V_{av} O_2} = \frac{\sqrt{M_{O2} }}{M_{CO2}}[/tex]

Now place these values to the above formula

[tex]\frac{V_{av}CO_2}{6.14\times 104 cm/s} = \frac{\sqrt{31.9988} }{44.0098}[/tex]

So,

V_av CO_2 is 5.24 ×  104 cm/s

hence, the average speed of [tex]V_{av} CO_2[/tex] is 5.24 ×  104 cm/s

The type of reaction represented by the above equation is -
decomposition
synthesis
single-replacement
double-replacement

Answers

Answer:

the type is single replacement

The given reaction equation represents a single-replacement reaction.

Explanation:

A chemical reaction is defined as the rearrangement of the atoms of a substance to give a new substance as a product.A decomposition reaction is a type of chemical reaction in which a substance breakdowns into two or more than two simpler substances.

                   ABC→ A+B+C

A synthesis reaction is a chemical reaction in which two or more compounds are combined together to form a single compound.

                   A+B+C → ABC

A single-replacement reaction is defined as the chemical reaction in which an element replaces another element from its compound.

                   AB+ C → AC + B

A double-replacement reaction is defined as the chemical reaction in which ions of compounds are exchanged.

                  AB+ CD → AC + BD

Given:

[tex]Fe + CuCl_2 \rightarrow FeCl_2 + Cu[/tex]

To find:

The type of chemical reaction represented by the given equation.

Solution:

In the given reaction:

[tex]Fe + CuCl_2 \rightarrow FeCl_2 + Cu[/tex]

Iron is replacing copper from its compound which is copper(II) chloride to give iron(II) chloride and copper as a product.

So from this, we can conclude that the given reaction equation represents a single-replacement reaction.

What is the mass % of acetone in a 1.77 M solution of acetone (MM = 58.08 g/mol) in water? The density of the solution is 0.971 g/mL.

Answers

Answer:

[tex]\%m/m=10.6\%[/tex]

Explanation:

Hello!

In this case, since the by-mass percent is defined by:

[tex]\%m/m=\frac{m_{solute}}{m_{solution}} *100\%[/tex]

Thus, since the given 1.77 M solution is given in terms of mol/L, we need to compute the mass of acetone via its molar mass and the volume of solution in L to g via the density:

[tex]\%m/m=1.77\frac{mol}{L}*\frac{58.08g}{1mol}*\frac{1L}{1000mL}*\frac{1mL}{0.971g} *100\%\\\\\%m/m=10.6\%[/tex]

A chemist combine did 3.50g of potassium level with chlorine gas to yield 6.6 7g of potassium for it. Assuming all the potassium was consumed, and that potassium chloride was the only product that formed, what mass of chlorine reacted?

Answers

Answer: mass of chlorine reacted is 3.18 g

Explanation:

2 K + Cl2 = 2KCl

no. of moles of K = mass / molar mass

= 3.50 / 39

= 0.0897

no. of moles of KCl = mass / molar mass

= 6.67 / 74.5

= 0.0895  

no. of moles of Cl2 required = number of moles of KCl / 2

= 0.0895 / 2

= 0.0448 moles  

mass of Cl2 required = no. of moles of Cl2 required x molar mass

= 0.0448 x 71

= 3.1808 g ≈ 3.18 g

Therefore mass of chlorine reacted is 3.18 g

5.00 ml of an H2SO4 solution with unknown molarity was diluted with 25.00 ml. This was tirated with 15.00ml of .1000 M NaOH to reach the equivalence point. What is the molarity of the original unknown H2SO4 solution? Also, what would the balanced chemical equation for this reaction be?

Answers

Answer:

0.1500 M

H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O

Explanation:

The balanced chemical equation is:

H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O

First we calculate how many NaOH moles reacted, using the volume and concentration:

15.00 mL * 0.100 M = 1.5 mmol NaOH

Then we convert NaOH moles into H₂SO₄ moles:

1.5 mmol NaOH * [tex]\frac{1mmolH_2SO_4}{2mmolNaOH}[/tex] = 0.75 mmol H₂SO₄

This amount of H₂SO₄ moles was originally contained within 5.00 mL of solution, thus the molarity is:

0.75 mmol H₂SO₄ / 5.00 mL = 0.1500 M

Option D shows correctly an ion pair and the correct formula for the ionic compound the two ions form.

Ion pairs of iron and oxygen react to form iron (III) oxide. The iron (III) oxide is one of the oxides of iron. The compound is usually attacked by acids and it is often called rust. It is used in the feedstock of the steel and iron industries. This means that the compound is used in the production of iron, steel, and many alloys.
