If two gases, A and B, in separate 1 liter containers exert pressures of 2 atm and 3 atm respectively, what will be the
pressure exerted when both gases are put together in a single
1 liter container?

What does the symbol (–hfus) indicate in a phase change?

Match the formula for the following compound:   magnesium sulfate heptahydratemgs·7h2omg2so4·7h2omg(so4)2·7h2omgso4·7h2o

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.
