A sample of nitrogen gas occupies a volume of 2.00 L at 756 mmHg and 0.00 C. The volume increases by 2.00 L and the temperature decreases to 137 K. What is the final pressure exerted on the gas?

The initial temperature of a 1.00 liter sample of argon is 20 C. The pressure is decreased from 720 mmHg to 360 mmHg and the volume increases to 2.14 liters. What was the change in temperature of the argon?

322 L of hydrogen occupies a volume of 197 L at STP. If the initial temperature of the hydrogen was 37 C, what was its initial pressure?

A sample of argon has a volume of 5.0 dm³ and the pressure is 0.92 atm. If the final temperature is 30C, the final volume is 5.7 L, and the final pressure is 800 mmHg, what was the initial temperature of the argon?

A sample of sulphur dioxide occupies a volume of 652mL at 40C and 720mmHg. What volume will the sulphur dioxide occupy at STP?

calculate the molarity and the molality of an NH3 solution made up of 30g of NH3 in 70g water. The density of solution is .982g/ml.

two containers of the same volume contain respectively a sample of oxygen at 1.52*10^(5)Nm^(-2) and a sample of nitrogen at 1.01*10^(5)Nm^(-2), what will be the pressure if both gases are held in the same container at the same temperature

Matter is made-up of very small particles. It is arranged and move according to its

state and it has a different type. The arrangement and the motion of the molecules or

particles is affected by (1) of attraction. The London Dispersion Forces; it is the

(2) among the types. It is acting between (3) and (4) where a (5) moments

induced in ordinary (6) molecules. Another type is (7) Forces,

there is an attractive force between polar molecules, wherein the partial (8) side of a

molecule is attracted to a partial (9) side of another molecule. Next, the (10) ,

the hydrogen atom interacts with (11) or nitrogen or (12) atom to form polar

bond. Lastly is the Ion-Dipole Forces that shows the interaction between the ion, whether

(13) or (14) , and the polar molecules. It is most common found in

(15) . Note that these forces of attraction have different strength.

A solution of hydrogen peroxide, H2O2, is 30.0% by mass and has a density of 11110g/L solution. Calculate the (a) molality, (b) molarity, and (c) mole fraction.
