Based on the graph, the correct option is that Marty is right because the change in concentration increases with time; option C.
<h3>What are decomposition reactions?</h3>
Decomposition reactions are reactions in which a large molecule splits or breaks down into two or more smaller molecules.
The general equation of a decomposition reaction is given below;
The decomposition of hydrogen peroxide to give water and oxygen occurs when it is exposed to air.
The given graph of the decomposition of hydrogen peroxide shows that the concentration of hydrogen peroxide decreases with time.
In conclusion, the decomposition of hydrogen peroxide in the presence of air gives oxygen and water.

We know that the average speed is simply the ratio of the
total distance travelled over the total duration of the trip.
total distance = 500 mi + 380 mi + 600 mi
total distance = 1,480 mi
total time = 10 h + 8 h + 15 h
total time = 33 h
So the average speed is therefore:
average speed = 1,480 mi / 33 h
<span>average speed = 44.85 mi / h</span>
Gravitational force is a non-contact force.
Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. It can either be kinetics or potential. In this problem you know it starting position so you can calculate it's potential energy (PE):
<span>PE=mass∗gravity∗height=0.3kg∗9.8m/s2∗1.8m=?
</span>The answer will typically be given in joules:
1J=kg∗m2s2 Could be wrong... But I believe it is 5.3...? as a final product.
