Answer:
Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
Explanation:
<span>The theoretical yield for a reaction is calculated based on the limiting reagent. This allows researchers to determine how much product can actually be formed based on the reagents present at the beginning of the reaction.</span>
<span>The actual yield will never be 100 percent due to limitations.</span>
Hi I'm in Chemistry too this year,
I believe D is correct because usually physical changes are things like density, color or quantity.
I cant entirely tell for now but an article on rodioactivity should solve the problem
