The reaction is a reduction reaction.
Answer:
This is False
Explanation:
A chemical change is when the matter is completely changed.
When you have water and boil it to be a gas, it is still the same matter, just in a different form.

Answer:
1.38 atm
Explanation:
Using Boyle's law which states that the volume of a given mass of gas is inversely proportional to the pressure, provided temperature remains constant
P1V1= P2V2
P1 = 2.2 atm, V1 = 2.5L ,
P2 = ? , V2 = 4L
2.2 × 2.5 = P2 × 4
Divide both sides by 4
P2 = 5.5 ÷ 4
P2 = 1.38 atm
