The percent abundance of the post-1982 pennies is 56%.

<h3>What is percent abundance?</h3>

Percent abundance is the percentage amount of all naturally occurring isotopes of an element.

<h3> Percent abundance of the post-1982 pennies</h3>

The percent abundance of the post-1982 pennies is calculated as follows;

percent abundance = number of  post-1982 pennies / total number of pennies x 100%

percent abundance =  (28) / (50) x 100%

percent abundance =  56%

Thus, the percent abundance of the post-1982 pennies is 56%.

A large piece of iron was reacted with an acid. What would happen to the rate of the reaction had the large piece been finely di
MAXImum [283]

Answer:

D: It will increase because smaller particles provide more surface area to react.

Explanation:

When the large iron is broken up into smaller pieces, there are more places for the iron to react (meaning there's more surface area). Think of it like taking the surface area of a big cube compared to the surface area of a bunch of small cubes. The sum of the surface areas of the small cubes will be greater than that of the large cube. As a result, more places for the iron to react will cause for a greater reaction.
