The amount of ................................. in the bonds of the products plus any energy GIVEN OFF WHEN THE PRODUCTS ARE FORMED.
During chemical reaction, energy are needed to break the chemical bonds which hold the molecules of the reactants together and energy is always given off when product are formed. At the end of the reaction, the quantities of these energies must be equal to show that energy is conserved.

The answer to this question is Released
This is the law of energy conservation that being done in order to reduce the total consumption of energy by using less energy.
In most cases, the conservation requires either by using the intial energy more efficiently or by reducing the total result of the energy formed.

The second order reaction A → Products takes 13.5 s for the concentration of A to decrease from 0.740 M to 0.319 M. What is the
Ivanshal [37]

The rate constant of the second order reaction is 0.137 M-1s-1.

<h3>What is the rate constant?</h3>

For the second order reaction we can write;

1/[A] = kt + 1/[A]o

[A]o = initial concentration

[A] = final concentration

k = rate constant

t = time

Now;

1/0.319 = 13.5k + 1/ 0.740

1/0.319 - 1/0.740 = 13.5k

3.13 - 1.35 = 13k

k = 3.13 - 1.35/13

k = 0.137 M-1s-1

What is the atomic mass/mass number of the atom in the diagram above?
Lelechka [254]

Answer:

the atomic number is 5

the atomic mass is 11

Explanation:

The atomic number is the amount of protons inside the nucleus, and this number also equals the amount of electrons. Since it shows you the nucleus and the electrons, all you need to do is count the protons (positive charge inside the nucleus) or count all the electrons (negative charge outside the nucleus, in the rings) and you should have your atomic number.

As for mass, all you need to do is count all the protons and neutrons inside the nucleus and add them up. Protons = 5, Neutrons = 6. (you add them since the equation for atomic mass is Atomic Mass = Protons + neutrons. This works every time)

5+6= 11, so your atomic mass is 11

I hope this helps :)

Table Salt or NaCl is composed of sodium and chlorine. While the individual elements of sodium and chlorine are very reactive, t
Deffense [45]

Answer:

Chlorine is more likely to steal a valence electron from sodium.

Explanation:

Sodium is number 11 on the periodic table with one valence electron. Belonging to the first group, it's one of the alkali metal, which are known to be highly reactive. Chlorine is number 17 with seven valence electrons, and it's in the second-to-last group of halogens--also very reactive.

Considering that elements with one valence electron are just about 100% likely to give up electrons to reach a stable state, sodium would be the element that is more likely to lose its valence electron to chlorine. In other words, chlorine would be the electron thief.
