Answer:
For example, the chemical formula for water is H2O which indicates that 2 atoms of Hydrogen combines with 1 atom of oxygen.
Explanation:
The chemical formula for sodium chloride (Salt) is NaCl indicating that one atom of sodium combines with one atom of chlorine in a one-to-one ratio.

Answer:
D
Explanation:
What an interesting amusing question.
The formula for KE = 1/2 m v^2.
v implies that there is motion.
The answer you are looking for is the body of water that has 0 for v.
A cloud moves, so it is not the answer.
A hailstone moves until it hits the ground. I'm assuming it's either on it's way down or it is caught in some sort of updraft in a cumulonimbus cloud. So it has motion.
Same comment for a raindrop. It has a v until it hits the ground so I'm assuming it is not the answer.
I've never seen a puddle of water move. It can only evaporate. So of all your choices, this one (D) is likely the right answer.
Answer:
Explanation:
Hello!
In this case, since the problem is providing mass, energy, and specific heat of water, we can write the following equation that relates them to each other:
In such a way, we get rid of both m and C, to solve for the change in temperature:
Now we plug in the data to obtain:
