The same mass of zinc as a powder will have a LOT more surface area per unit mass than the same mass as an ingot (block). Since the reactions take place at the surface, the more surface you have, the faster the reaction.
"More rapidly" indicates a greater degree of speed compared to "rapidly." Use "more rapidly" when describing an action that is quicker or accelerating at a faster pace.
By making the particles finer, you increase the total surface area where zinc comes into contact with water. Greater surface area means more of your reactants are available to react. Below is a link to wikipedia's entry for chemical kinetics.
Black powder, in fact is the term used in fireworks. Otherwise, it may be referred to as gunpowder although black powder has now become a more acceptable term because it is no longer used in guns(except for the antique ones). Guns now utilize smokeless powders.
Powdered magnesium has a greater surface area compared to a strip of magnesium, which allows for more contact with the reactant, such as oxygen from the air. This increased surface area results in a faster reaction rate, as more magnesium atoms are available to react at the same time.
It depletes rapidly at low temperatures. This is the reason for ozone depletion at poles.
Potassium (K) reacts most rapidly with water.
Magnesium powder has a larger surface area, allowing for more contact between the magnesium and the hydrochloric acid, leading to a faster reaction. The increased surface area of the powder results in more collisions between magnesium particles and acid molecules, increasing the rate of reaction.
Baking powder is a single-acting leavening agent that reacts once it is mixed with liquid. Double-acting baking powder reacts twice, once when mixed with liquid and again when exposed to heat, providing a more consistent rise in baked goods.
Whey protein powder is better because it is completely safe and natural product.It has great ability to be digested rapidly. You can get more information from blog.energyfirst.com/

Placing the object on top of the ice block is more effective for cooling because direct contact between the object and the cold surface helps transfer heat more efficiently. The ice block will absorb heat from the object more rapidly when placed underneath.
