Answer:
0.25L
Explanation:
Using the dilution formula
C1V1=C2V2
C1=6M
V1?
C2=0.75M
V2=2.0L
V1= C2V2/C1
V1=0.75*2.0/6
V1=0.25L
Answer:
Gas to Solid
Explanation:
A condensation reaction goes from gas to solid
Condensation is a physical change which alters the physical properties of matter particularly the form and state. In a condensation reaction, a gas goes from solid to liquid.
It is the inverse of the sublimation reaction.
- It involves the loss in energy by a gas.
- When gases lose energy, they become pulled together by attractive forces.
- This changes their state to solid with enough loss in energy.

Oceans, Fossil fuels, atmosphere
