Answer:
Combination or synthesis
Explanation:
The given reaction is:
6Li + N₂ → 2 Li₃N
This reaction is a synthesis or combination reaction. 6 moles of Li combines with nitrogen gas to produce 2 moles of Li₃N.
In a synthesis reaction, two substances combines together to give singular product. The formation of compounds from the union of the constituent elements falls into this category of reaction.Which example shows how genetic engineering can be used in the agricultural industry?

A ball is moving at a speed of 6.70 m/s. If the kinetic energy of the ball is 3.10 J, what is the mass of the ball?
Answer:
0.14 kgExplanation:
The mass of the ball can be found by using the formula
[tex]m = \frac{2k}{ {v}^{2} } \\ [/tex]
v is the velocity
k is the kinetic energy
From the question we have
[tex]m = \frac{2(3.10)}{ {6.70}^{2} } = \frac{6.20}{44.89} \\ = 0.138115...[/tex]
We have the final answer as
0.14 kgHope this helps you
What is the similarity between teeth and eggshells?
Explanation:
Because they share a similar composition, similar chemicals affect their structures in positive or negative ways. For example, fluoride – a staple in many dental practices – strengthens both enamel and eggshells and helps protect them from acids. Acids weaken and break down both substances. Scientists find this particularly concerning given that the ocean is growing increasingly acidic. They fear this may weaken the eggs of some marine species and harm their chance of survival. Most dentists recommend limiting aggressively acidic foods and beverages such as soft drinks.
Which learning theory is based on associative learning?
Answer:
1. Classical conditioning. Classical conditioning is a type of associative learning based on the association between a neutral stimulus with another that is significant for a person or an animal in order to generate a similar response.

What is the only force that acts on a falling body when it is in free fall?
Answer:
Gravity
Explanation:
Objects that are experiencing free fall, are not encountering a significant force of air resistance or as a matter of fact any other kind of forces, they are falling under the complete control of gravity.
According to Le Chatelier's principle, what happens to the equilibrium constant (K) when the concentration of the reactants is doubled? The value of the equilibrium constant (K) is doubled. The value of the equilibrium constant (K) is halved. The value of the equilibrium constant (K) remains the same. The value of the equilibrium constant (K) changes unpredictably.
Answer:
The value of the equilibrium constant (K) remains the same.
Explanation:
A state of dynamic equilibrium is said to have been achieved in a reaction system when the rate of forward reaction equals the rate of reverse reaction.
At equilibrium, doubling the initial concentration of reactants have no effect on the equilibrium constant K. The equilibrium will rather shift to the left or right as required in order to annul the constraint.
Answer:
C
Explanation:
When glucose is totally oxidized to CO2 and H2O, how many ATP molecules are made by oxidative phosphorylation out of a maximum yield of how many ATP molecules?
Answer: 26 out of 30.
Explanation:
Out of 30 ATP molecules, 26 are produced from maximum oxidative phosphorylation production. Two more come from glycolysis and two more are from the citric acid cycle.
To power other cellular processes, ATP captures and releases chemical energy obtained from the breakdown of food molecules.

You are eating dinner with your familiy one night. Your little brother (Who is a disgusting monster ) asked if you likes "seafood?" When you said yes, He proceeded to show you his chewed up, or "See Food". Did a chemical reaction take place, yes or no? What evidence or lack of evidence do you have to support your answer?
Answer:
yes eating the food involves both physical and chemical changes. The chewing of food is a physical change, while the mixing of saliva with food triggers chemical reactions
Explanation:
Once the food mixes with the saliva in our mouth, chemical reactions start taking place in the food, leading to its breakdown and changes in its chemical composition. An evidence of the chemical changes is the taste that we feel when we eat something sweet or sour etc.

Which particle has no mass and no charge?
O alpha
O beta
gamma
O
neutron
Answer:
Neutrons
Explanation:
determine the number of charged particles in nucleus of calcium atom then deduce the number of electrons
NUCLEAR CHARGE (20+)
ATOMIC MASS (40 amu)
given the relative charge of a proton =1+\ m1nucleon=1amu
Answer:
detail is given below.
Explanation:
The charged particles of nucleus are protons while neutrons are neutral having no charge.
We know that an atom consist of electrons, protons and neutrons. Neutrons and protons are present inside the nucleus while electrons are present out side the nucleus.
Electron has a negative charge and is written as e⁻. The mass of electron is 9.10938356×10⁻³¹ Kg . While mass of proton and neutron is 1.672623×10⁻²⁷Kg and 1.674929×10⁻²⁷ Kg respectively.
Symbol of proton= P⁺
Symbol of neutron= n⁰
The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons.
one proton contribute 1 amu to the total weight. There are 20 protons and 20 neutrons in Ca thus its atomic mass is 40 amu.
While the atomic number is 20.
the filament in an electric light bulb is made from a. platinum b. fiberglass c. aluminum d. tungsten
Please if you don't know don't answer
Answer:
Mass = 50kg, a = 20m/sec^2
F = MA
F = 50 * 20
F = 1000N
F = MA
650 = M * 10
M = 650/10 = 65kg
The phenomenon of weightlessness occurs when there is no force of support on your body. when your body is effectively in free fall, accelerating downward at the acceleration of gravity, then you are not being supported.
F = Gm1m2/distance^2
F = 6.6726* 10 ^-11 * 70 * 5.98 * 10^24/(6.38 * 10^6)^2

Which sample contains the same number of atoms as a gram-atomic mass of He?
1.
6 g of C
2.
7 g of Li
3.
8 g of o
4.
9 g of F
Submit Answer
Answer: 2. 7g of Li
Explanation: A mole of any substance contains the same number of particles (Avogadro's number, 6.02*10^23). 1 gram atomic mass of He (4g) is equivalent to 1 mole; so is 1 gram atomic mass (7g) of Li

What math is used to find density?
Answer:
[tex]\huge\mathtt{{\colorbox{silver}{ANSWER~~~↴}}}[/tex]
Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). Remember, grams is a mass and cubic centimeters is a volume (the same volume as 1 milliliter).

How does knowing the meaning of prefix-trans help you remember what happens to light that strikes a translucent object ?
Explanation:
The prefix trans- and its variant tra- mean "across".
A translucent substance allows some light to go "across" it to the other side. Also, think about a transparent substance: it allows light to go "across" it; or a translation, it is a going "across" from one language into another.

What of these should Hailey include in her list?
Synthetic polymers are biodegradable.
Synthetic polymers are not flexible.
Synthetic polymers are recycled cheaply.
Synthetic polymers are inexpensive to produce.
Answer:
Hailey should add, they are inexpensive to produce.
Explanation:
Reason being why they are inexpensive to produce, is due to them being chemical based and easy to product in the factory setting. Which makes them extremely cheap to make.
Reason being why the others are wrong, synthetic polymers are not biodegradable as they are made in a factory with oils. Synthetic polymers are not flexible due to them being used for harder products. Synthetic polymers are not recycled cheaply as they are made with chemicals which makes it very hard to recycle.

Determine the number of moles in a sample of calcium that contains 6.34 x 1022
atoms.
Answer:
0.105 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{6.34 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.105315...[/tex]
We have the final answer as
0.105 molesHope this helps you

Explanation:

bigger size elements have low ionization energy and high shielding effect .justify the statement
Bigger size elements have low ionization energy and high shielding effect because:
Shielding effect:This effect describes the decrease in attraction between an electron and the nucleus in any atom with more than one electron shell. The more electron shells there are, the greater the shielding effect experienced by the outermost electrons.When shielding effect decreases the attraction force exerted by the nucleus increases on valence electrons.As a result, atoms will be larger.Find more information about Shielding effect here:
