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.

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.
What will happen if turmeric strip reacts with baking soda solution?
the colour of the yellow strip changes into red..
What is the purpose of emery board?
Emery Boards are made of emery which is a rock.
If a student dissolves powdered sugar in a water in a beaker the student then places a strip of silver in the beaker what is the solute in this solution?
The solute in this solution is the powdered sugar that was dissolved in water. Silver is not a solute in this case, it is a separate material added to the beaker. The powdered sugar molecules are the ones that get dispersed throughout the water.
How does a thermostat control the temperature of a building?
A bimetallic strip is made of two different metals joined firmly together as the strip is heated one metal expands more then the other the strip is forced to coil more tightly when the strips cools the process rapidly and uncoils again , movements of the strip can operate an electrical switches
What is the coating on a magnesium strip?
The coating on a magnesium strip could be magnesium oxide or magnesium hydroxide, which forms naturally when magnesium reacts with oxygen or water in the atmosphere.
Why did glucose test strip change colour after saliva was added?
The change in color of the glucose test strip after adding saliva is due to the presence of glucose in saliva. The strip contains a chemical that reacts with glucose to produce a color change, indicating the presence and concentration of glucose in the saliva sample.
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.
Is burning a strip of magnesium ribbon a chemical or physical change?
Burning a strip of magnesium ribbon is a chemical change because the magnesium reacts with oxygen in the air to form magnesium oxide. This reaction results in the formation of new substances with different properties than the original magnesium ribbon.
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.
What is the future tense of strip?
