Choose the electron dot formula that most accurately describes the bonding in CS2. (Hint: Consider formal charges.)

Consider the molecule and the following hybridization choices:What is the hybridization of the nitrogen atom?

You have a certain mass of helium gas (He) in a rigid steel container. You add the same mass of neon gas (Ne) to this container. Which of the following best describes what happens? Assume the temperature is constant.

It is found that 250. mL of a gas at STP has a mass of 0.700 g. What is the molar mass?

The Lewis structure for H3BO3 is

Draw the Lewis structures of the molecules below and use them to answer the following questions: I.BH3II.NO2III.SF6IV.O3V.PCl5Which of these molecules show resonance?

Zinc metal is added to hydrochloric acid to generate hydrogen gas, which is collected over a liquid whose vapor pressure is the same as pure water at 20.0°C (18 torr). The volume of the gas mixture is 1.7 L and its total pressure is 0.810 atm.Determine the number of moles of hydrogen gas present in the sample.

A sample of gas is in a 50.0-mL container at a pressure of 645 torr and a temperature of 25°C. The entire sample is heated to a temperature of 35°C and transferred to a new container whose volume is 98.7 mL. The pressure of the gas in the second container is about:

A gas sample is heated from -20.0°C to 57.0°C and the volume is increased from 2.00 L to 4.50 L. If the initial pressure is 0.140 atm, what is the final pressure?

The force between two bodies having identical electric charges
