Answer:
<em>I disagree with the student's claim</em>
<em></em>
Explanation:
<em>From basic chemistry, the rate of chemical reaction increases with an increased surface area.</em>
<em>This simply means that a powdered substance will react faster than a small pellet of the same substance.</em>
Let us break this down further. The pellet has a smaller exposed surface per grain to the solvent, here is how. Imagine the powdered substance bunched up together to make the small pellet, grains at the center of the pellet is blocked by other grains around it, and will take time before it comes in contact with the solvent. For the powdered grains, each grain has a surface independently exposed to the solvent and can easily come in contact with the solvent, taking less time to react with the solvent.
Technically, a powdered substance has more exposed surface area and logically will take a shorter time for the reaction to be complete.
There are approximately 70.906
Answer:
202,020 pennies
Explanation:
The amount of pennies in 1 dollar is 100.
Basically, you just multiply the whole dollar amount (2020) by 100 and then add 20 to find the amount of pennies.
(2020)(100)+20= 202,000+20= 202,020 pennies.
Answer:
Heat
Explanation:
Temperature is the average thermal energy (or heat) in a substance. Sound isn't really related, thermometers measure temperature, and chemical reactions can produce heat, but none of those are measured by temperature.
Epsom salt is a compound.
