Answer:
<h2>0.93 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 37.2 g
volume = 40 mL
We have

We have the final answer as
<h3>0.93 g/mL</h3>

Answer:
DECREASE BY A FACTOR OF FOUR
Explanation:
Using pressure equation:
P 1 / T1 = P2 /T2 (at constant volume)
P1 = P
T1 =T
P2 = ?
T2 = 4 T
So therefore;
P2 = P1T1/ T2
P2 = P T/ 4 T
P2 = 1/4 P
The pressure is decreased by a factor of four, the new pressure is a quarter of the formal pressure of the gas.
Answer:
2Cl+2e -->2Cl^-
Explanation:
reduction is the gain of electrons and this is the only option which fits the definition.
