this is base don Boyle law
PV= constant at constant temperature
P1V1=P2V2
here the V2= V1/2
P1 *V1 =P2* V1/2
P1 *2 = P2
it mean pressure of gas is doubled
<span>C2H4O + H2O = C2H6O2
moles water = 18 g/ 18.02 g/mol=.998
the ratio is 1 : 1 : 1
moles C2H4O needed = 0.998
mass C2H4O = 0.998 mol x 44.053 g/mol = 44.00 g
We require 44.00 g of ethylene oxide is needed to react with 18 g of water.</span>
Answer:
The average kinetic energy of the particles in a gas is proportional to the temperature of the gas.
Explanation:
Because the mass of these particles is constant, the particles must move faster as the gas becomes warmer.
Keeping your arm straight in front of you, you rotate 90° to your left, and see the left side of the circle lit while the right side is dark. Half the ball is still lit up, but you can see only part of the lit area. As you continue to rotate, you see a different amount of the ball.
Answer:
CONVECTION
Explanation:
CONVECTION: In liquids and gases, convection is usually the most efficient way to transfer heat. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas.
