A student is designing an experiment about the factors that affect math

grades. Which statement best represents a possible hypothesis for this

experiment?

B. If students spend at least 1 hour per night studying math, then  they will get a grade of 85 or higher.

Explanation: A hypothesis is defined as a tentative or predictions or an educated guess of scientific questions. A hypothesis is always done before performing an experiment.

The correct hypothesis for the given experiment will be "If students spend at least 1 hour per night studying math, then  they will get a grade of 85 or higher" because it has an if-then statement which is a conditional statement where statement after "if represents hypothesis" and "then represents conclusion".

Hence, the correct answer is "B. If students spend at least 1 hour per night studying math, then  they will get a grade of 85 or higher."

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
