D. The total number of gas molecules will decrease.
Explanation:
According to Le Chatelier's principle, an increase in pressure in a system involving gases will cause the total number of gas molecules to decrease.
Le Chatelier's principle states that "if any conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".
In a reaction involving gases, a change in pressure affects only reactions in a gaseous phase.
An increase in pressure on an equilibrium system will shift the position of the equilibrium to the side having smaller volume and vice versa.

Answer:
Mass of iron = 59.375 gm
Explanation:
Calories ( or joules) are added to the water by the hot steel so at the endpoint they are BOTH at 40 C
The water gains:
4.18 j/g-C * 50 * (40-30 C) = 2090 j
The steel gave up 2090 j going from 120 to 40 C
2090 = .44 j/g-C * m * (120-40) solve fro m = 59.375 gm

6 divided by 6 is 0
4 divided by 2 is 2
hope i helped any :))
Answer:
it has a fixed volume it can also be compressed
Explanation:
a gases molecules don't move slow because they are not solid and are not compacted.
a gas does not have a fixed shape because there is nothing to hold its shape
