Answer:
heat is the movement from areas of <u>high </u>temperature to areas of <u>low </u>temperature
Answer:
Explanation:
To solve the problem, we must know the kind of compounds we are dealing with.
For the first compound, P1 and second compound P2:
N O N O
Mass percent 64.17 35.73 47.23 52.79
Atomic mass 14 16 14 16
Number of
moles 64.17/14 35.73/16 47.23/14 52.79/16
4.58 2.23 3.37 3.30
Simplest
ratio 4.58/2.23 2.23/2.23 3.37/3.30 3.3/3.3
2 1 1 1
P1 compound is N₂O
P2 compound is NO
These are the compounds,
In N₂O = 28:16
NO = 14:16
This is the ratio of nitrogen to a fixed mass of oxygen for the two compounds.
D . Water evaporating in the water cycle is an open system
One mole of gas occupies 22.4 liters, 5*1/22.4=0.22 moles of carbon dioxide ration of oxygen to carbon dioxide is 1:2 so we divide 0.22 by 2 we get 0.11 moles of oxygen 1 mole occupies 22.4 litres, what if 0.11 moles of oxygen were used what volume would it occupy. so 0.11*22.4/1=2.5L
According to the gas law, the pressure of the gas is related to the temperature when the volume is constant as P1/T1=P2/T2. So the pressure will increase and the container may explode.
