Alexxandr [17]
This is a decomposition reaction, where ammonium nitrate is heated and decomposed to gaseous water and dinitrogen oxide.
Formulas for reactants and products with states are as follows;
ammonium nitrate - NH₄NO₃ (s)
water - H₂O (g)
dinitrogen oxide - N₂O (g)
balanced reactions when the masses of both sides of the equation must be balanced 

Balanced chemical equation 
NH₄NO₃(s) ---> 2H₂O(g) + N₂O(g)

Why is it essential for a calorimetry to be an insulated (closed) system?
aksik [14]

Answer:

B.Thermal insulation minimizes energy loses to the atmosphere.

Explanation:

It is important because it helps to stop hit from transferring from the calorimeter to the environment. This would help to have an accurate measurement of the heat that was used in the chemical process. The greatest cause of error that happens in calorimetry is when heat is lost to the environment. To reduce this, you insulate the calorimeter and add a cover.

What is normality in chemistry?​
Advocard [28]

Answer:

a measure of concentration equal to the gram equivalent weight per liter of solution.

Explanation:

Gram equivalent weight is the measure of the reactive capacity of a molecule. The solute's role in the reaction determines the solution's normality. Normality is also known as the equivalent concentration of a solution.

Help ASAP!!! I need it now i have to write similar test tmrw
dusya [7]
A is Ea, which stands for activating energy. Energy is needed to get the reaction underway and Ea is the energy needed to “start” the reaction.

B is the temperature either released or absorbed.

The diagram shows that the reaction is exothermic based on the fact that the products energy is lower than the reactants. That is because energy (which is temperature in this case) is released during the process. If the reactants would have been lower than the products, the reaction would be endothermic.
