Answer is: B) The kinetic energy is increasing proportional to the mass of the bowling ball.
Kinetic energy has to do with the speed of an object and how much mass it has; basically how the object is moving.
Ek = 1/2 · m(bowling ball) · v²(bowling ball).
m is mass; v is speed of bowling ball.
The standard unit of kinetic energy is the joule.
<u>Answer:</u> The given amount of iron reacts with 9.0 moles of
and produce 6.0 moles of 
<u>Explanation:</u>
We are given:
Moles of iron = 12.0 moles
The chemical equation for the rusting of iron follows:

By Stoichiometry of the reaction:
4 moles of iron reacts with 3 moles of oxygen gas
So, 12.0 moles of iron will react with =
of oxygen gas
- <u>For iron (III) oxide:</u>
By Stoichiometry of the reaction:
4 moles of iron produces 2 moles of iron (III) oxide
So, 12.0 moles of iron will produce =
of iron (III) oxide
Hence, the given amount of iron reacts with 9.0 moles of
and produce 6.0 moles of 
Explanation:
Rosa eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mostly starch. Rosa plans to go for a run later this afternoon. Rosa is breathing normally. does she need from the food she ate and the air she breathes so that she can go on her run? (Sentence starter: The molecules Rosa needs from the food she eats and air she breathes are.

Answer: First option is correct
Explanation:
Irrespective of the path taken by a reaction, If a reaction is carried out in a series of steps, the ΔH for the reaction will equal the sum of the enthalpy changes for the individual step,
