Answer:
25%
Explanation:
Ammonium Chloride NH4CI Fertilizer-grade NH4Cl usually contains 25% N. About two-thirds of the world capacity for manufacture of this material is located in Japan, with the remaining one-third situated in India and China.
Answer : The value of 
for the reaction is, -565.6 kJ
Explanation :
First we have to calculate the molar mass of CO.
Molar mass CO = Atomic mass of C + Atomic mass of O = 12 + 16 = 28 g/mole
Now we have to calculate the moles of CO.
Now we have to calculate the value of for the reaction.
The balanced equation will be,
From the balanced chemical reaction we conclude that,
As, 
of CO release heat = 10.1 kJ
So, 2 mole of CO release heat = 
Therefore, the value of for the reaction is, -565.6 kJ (The negative sign indicates the amount of energy is released)
Answer:
Examples of radioactive isotopes include carbon-14, tritium (hydrogen-3), chlorine-36, uranium-235, and uranium-238.
Im sorry but its a pdf i can write on it :(
The result which occurs during an exothermic reaction is: C. Light and heat are released into the environment.
A chemical reaction is defined as a chemical process involving the continuous transformation and rearrangement of either the ionic, atomic or molecular structure of chemical elements, especially through the breakdown and formation of chemical bonds, so as to produce a new chemical compound.
Basically, the two (2) main types of chemical reaction are;
- <u>Endothermic reaction:</u> this is a chemical reaction in which heat is absorbed
.
<u>Exothermic reaction:</u> this is a chemical reaction in which light and heat is liberated (released) into the environment.
In an exothermic chemical reaction, light and heat energy is liberated (released) when the energy of the products is lesser than the energy of the reactants.
In conclusion, light and heat is liberated (released) into the environment during an exothermic reaction.
