JudyPowdered 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.

What deposit covers a zinc strip grey?
The deposit that covers a zinc strip and gives it a grey appearance is likely zinc oxide or zinc carbonate. These compounds can form on the surface of zinc when it reacts with oxygen or carbon dioxide in the air, giving it a dull grey color.
Does strip-n-all evaporate quicker than water?
Generally, strip-n-all, which is a paint remover, is designed to evaporate quicker than water. This is because paint removers contain solvents that have a lower boiling point compared to water, allowing them to evaporate more rapidly.
How and why does the mass of a magnesium strip change when it is heated strongly in air?
When a magnesium strip is heated strongly in air, it undergoes a chemical reaction called oxidation. Magnesium reacts with oxygen in the air to form magnesium oxide. The mass of the strip increases because magnesium combines with oxygen atoms from the air to form a heavier compound (magnesium oxide).
How many different kinds of strip games are there?
There are many different kinds of strip games. Strip poker is probably the most well known. Others include strip scrabble, strip twister and strip chess.
How does a glucose test strip work?
A glucose test strip contains an enzyme that reacts with glucose in a blood sample. When blood is applied to the strip, the enzyme converts glucose into a detectable signal, such as a color change or electrical current. The meter then reads this signal to measure the glucose level in the blood sample.
