Answer:
A
Explanation:
When a reaction happens some of the reactants mass is released as energy so the mass of the product would be less
Because different objects give out electromagnetic radiation at different frequencies. Some objects are very ea...

As temperature increases, the particles will gain kinetic energy causing it to move more rapidly and randomly. However, this causes the gas to expand as the particles will have more energy to roam freely. Hence as temperature increases, Volume increases.
This is based on Charles' Law stating that the volume of a gas is directly proportional to its absolute temperature.
An acid dissociation constant, Ka<span>, (also known as acidity </span>constant<span>, or </span>acid<span>-ionization </span>constant<span>) is a quantitative measure of the strength of an </span>acid<span> in solution. It is the equilibrium </span>constant<span> for a chemical reaction known as </span>dissociation<span> in the context of </span>acid<span>–base reactions.
Hope this helped!

Answer: A
Explanation: A, because when you eat it is you use chemical energy afterward you run and use mechanical energy. Ex of Chemical energy can be batteries and you digesting food. Mechanical is movement.
