Answer: The excess amount changes from a gas into a liquid or solid (ice). The process of water changing from a gas to a liquid is called "condensation," and when gas changes directly into a solid, it is called "deposition." These two processes are how clouds form.
Answer:
B
Explanation:
The warmer the water, the more space it takes up, and the lower its density.
Answer:
<u>Why is it important to keep the two sides of an equation balanced when solving?</u>
If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true.
<u>What other properties do we use to rewrite expressions and equations?</u>

Answer:
Force of attraction = 35.96
N
Explanation:
Given: charge on anion = -2
Charge on cation = +2
Distance = 1 nm =
m
To calculate: Force of attraction.
Solution: The force of attraction is calculated by using equation,
---(1)
where, q represents the charge and the subscripts 1 and 2 represents cation and anion.
k = ![8.99 \times 10^9 \ Nm^{2}C^{-2}](https://tex.z-dn.net/?f=8.99%20%5Ctimes%2010%5E9%20%5C%20Nm%5E%7B2%7DC%5E%7B-2%7D)
F = force of attraction
r = distance between ions.
Substituting all the values in the equation (1) the equation becomes
![F = \dfrac{8.99 \times 10^9 \times 2 \times 2}{ \left ( 10^-9 \right )^2 }](https://tex.z-dn.net/?f=F%20%3D%20%5Cdfrac%7B8.99%20%5Ctimes%2010%5E9%20%5Ctimes%202%20%5Ctimes%202%7D%7B%20%5Cleft%20%28%2010%5E-9%20%5Cright%20%29%5E2%20%7D)
Force of attraction = 35.96
