3L of a gas is at a temperature of 78°C. Find the volume of the gas at 0°C

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.

Assume that 13.5 g solid aluminum (al) react with hcl to produce solid aluminum chloride (alcl3) salt and gaseous hydrogen (h2) at standard temperature and pressure.

Write the balanced chemical reaction for the formation of fe2(so4)3 from fe2o3 and so3 and determine how many moles of fe2(so4)3 are formed when 12.7 mol of so3 are reacted.
