Not 100% sure if its right.
When an object covers equal distances in equal amounts of time, it is moving at a constant speed.
B. When electrons gain energy, they have the power to move up to a higher energy level in an atom.
Answer:

Explanation:
Hello,
In this case, the chemical reaction is:

Thus, we first identify the limiting reactant by computing the yielded moles of water by both of the reactants:

In such a way, since HBr yields less water than cadmium hydroxide, we infer that HBr is the limiting one, therefore, the yielded mass of water are:

Regards.
Answer:
A
Explanation:
CO2 cylinder, 68% full by water capacity, warms up to room temperature (70 oF), the pressure inside the cylinder increases to 837 psi. When the same cylinder reaches 87.9 oF the entire charge becomes a gas no matter what the pressure.
The answer is large leaves.
These enable the plant to absorb more of the scarce sunlight it receives, so it can create enough nutrients for it to survive.
