Traditionally, gunpowder used in fireworks was made of 75 percent potassium nitrate also called saltpeter mixed with 15 percent charcoal and 10 percent sulfur; modern fireworks sometimes use other mixtures (such as sulfurless powder with extra potassium nitrate) or other chemicals instead
A would because its amplitude is higher than B's Hope this helps :D
Atoms combine because they are all working toward getting 8 valence electrons, except for noble gases. It is in their nature.
If you need a better explanation just ask in the comments.

Your task is to measure the amount of energy evolved during the combustion of some hydrocarbon, then the ideal technique for this experiment would be : Bomb calorimetry
<h3>What is bomb calorimetry?</h3>
Hydrocarbons are combustibles means that they can react in a combustion reaction to produce energy. To measure this energy, it's a necessary equipment so that the reaction can be placed in a controlled way.
The bomb calorimeter is the equipment, which is an adiabatic vessel, with water and heat is calculated based on the increase in the temperature of the water.
Coffee-cup calorimetry is used to measure the heat of a dissolution reaction and bomb manometry is used to measure the pressure.
