Answer:
density equals weigt divided by volume
Explanation:
Answer:
Changing the surface area from minimum to maximum increases the number of reactants in a chemical reaction.
An increase in surface area of a solid reactant means more of its particles are exposed to attack by the other Particle. This results in an increased chance of collisions between reactant particles, so there are more collisions in any given time and the rate of reaction increases.
A suitable hypothesis might be that temperature affects the rate of chemical modification, and the independent variable is temperature.
<h3>What is a hypothesis?</h3>
A hypothesis is a given explanation about a question that emerged by observing form the real world.
In this case, the dependent variable is the rate of chemical modification because this variable is modified in the experiment.
In conclusion, a suitable hypothesis might be that temperature affects the rate of chemical modification, and the independent variable is temperature.
