Answer:
The answer is
<h2>40.0 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 420 g
density = 10.5 g/cm³
The volume is
We have the final answer as
<h3>40.0 mL</h3>

Answer:
1. A
2. C
Explanation:
For the first question, we know that the water transformed into a gas. This fact eliminates choices C and D, primarily because they describe the change as "gas to liquid" instead of liquid to gas.
What separates B from A is that B is saying the liquid changed to a gas in response to sunlight, which is completely false and impertinent to the prompt.
A is the correct answer.
for the second question, we know that condensation causes clouds -- and that neither evaporation nor water vapor would clear clouds to make more of them, which eliminates choices B and D. Going back to condensation, the accumulation of water vapor plays a big role in the formation of clouds. While evaporation does play a part in [it] as well, condensation is what caused the sudden appearance of clouds in the troposphere.
C is the correct answer.
Answer:
Explanation:
Filtration can be used to separate an insoluble solid from a liquid, or a precipitate from the reaction mixture in which it formed. The solid which collects in the filter paper is called the residue. The clear liquid which passes through the filter paper is called the filtrate.
