Answer:
<u>It increases by a factor of four</u>
Explanation:
Boyle's Law : At constant temperature , the volume of fixed mass of a gas is inversely proportional to its pressure.
pV = K.......(1)
pV = constant
Charles law : The volume of the gas is directly proportional to temperature at constant pressure.
V = KT
or V/T = K = constant ....(2)
Applying equation (1) and (2)


According to question ,
T2 = 4 (T1)
V2 = V1
Put the value of T2 and V2 , The P2 can be calculated,

V1 and V1 cancel each other
T1 and T1 cancel each other
We get,

or
P2 = 4 P1
So pressure increased by the factor of four
Moles = Molarity x Volume
Moles = 2.0 x 0.50
= 1.0 mole
hope this helps!

Explanation:Please see attachment for explanation
.....i don't understand the question sorry
Answer:
Mass of copper oxide: 10g
Mass of copper: 8.882g
Mass of oxygen: 1.118g
<u> Cu</u> <u>O</u>
8.882 1.118
Divide by
8.882÷63.5 1.118÷16
0.14 0.07
Divide by the lowest number 0.14/0.07 0.07/0.07
2 1
Check the ratio now, Cu has 2 atoms and O has 1 atom .
The formula is
