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.

Powdered mg reacts morre rapidly than strip of mg?
true, because of more surface area
Why Powdered Zn reacts more rapidly with water than the chunks of metallic Zn?
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.
Does Sodium and water to produce fire?
*sodium metal ignites upon exposure to water Because sodium floats on water so it can stay burning, to put out a sodium or oil fire it has to be deprived of air (Powder or covering with fire proof blanket etc.)
Does ozone decompose more rapidly at high or low temperatures?
It depletes rapidly at low temperatures. This is the reason for ozone depletion at poles.
Why does carotenes move more rapidly with the solvent then the xanthophylls?
The reason that carotenes move more rapidly with the solvent than the xanthrophylls is likely due to polarity. Xanthrophylls are fairly nonpolar, but carotenes are even more nonpolar.
Which element reacts more rapidly in water lithium or potassium?
Potassium (K) reacts most rapidly with water.
Why magnesium powder reacts more rapidly than magnesium ribbon with hydrochloric acid?
There is far more total surface area available for the reaction to occur on than just the ribbon.
Powdered mg reacts morre rapidly than strip of mg?
true, because of more surface area
Why whey protein powder is better than other powders?
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/
What is the reaction for potassium chloride and water?
Potassium reacts rapidly and vigorously with water to produce colourless basic potassium hydroxide solution. In this reaction hydrogen gas is liberated. This reaction is highly exothermic. On evolution of heat potassium becomes purplish.2 K (solid) + 2 H2O (liquid) -> 2 KOH (aqueous) + H2 (gas)Additionally, hydrogen released during the reaction strongly reacts with oxygen and ignites. Potassium reacts with water more slowly than does rubidium. It reacts with water more rapidly than does sodium.
What is the comparative to rapidly?
more rapidly
What is comparative for rapidly?
more rapidly
What is the comparative and superlative to the word rapidly?
more rapidly and most rapidly
Why would a large lump of copper oxide react slower with sulfuric than if copper oxide is used in powdered form?
Powder reacts quicker because it has more surface area, so there are more particles reacting.
What is the comparative word for rapidly?
more rapidly
What is comparative tense of rapidly?
more rapidly
What is the comparative form for rapidly?
more rapidly
