Exothermic reaction normally gives out heat for completing the reaction. the burning of a candle or the condensation of water vapour to water are all exothermic reactions. The prefix "ex" at the begining refers to external or outside and normally these kind of reactions release heat at the end.During neutralization, when the acida and bases are combined, it releases heat and this kind of reaction is definitely exothermic reaction.The combustion of any kind of fuel is also exothermic reaction as it gives out heat at the end.Fossil fuel burnt in cars and engines are good examples.
The answers are,
<u>B. If the container is cooled, the gas particles will lose kinetic energy and temperature will decrease.</u>
<u>C. If the gas particles move more quickly, they will collide more frequently with the walls of the container and pressure will increase.</u>
<u>E. If the gas particles move more quickly, they will collide with the walls of the container more often and with more force, and pressure will increase.</u>

Answer:
Ionul de hidroniu este un factor important atunci când avem de-a face cu reacții chimice care apar în soluții apoase. Concentrația sa în raport cu hidroxidul este o măsură directă a pH-ului unei soluții. Se poate forma atunci când un acid este prezent în apă sau pur și simplu în apă pură. Formula chimică este H3O +
Explanation:
The hydronium ion is an important factor when dealing with chemical reactions that occur in aqueous solutions. Its concentration relative to hydroxide is a direct measure of the pH of a solution. It can be formed when an acid is present in water or simply in pure water. It's chemical formula is H3O+
marke me as brainliest please
I cant help unless there is an article..
