If the coefficient of volume expansion of mercury is βhgβhgbeta_hg = 1.80×10−4 /k/k , compute βglassβglassbeta_glass, the coefficient of volume expansion of the glass.

What is the percentage of hydrogen in c2h4

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.

Which factor is likely to impact the possible number of compounds? presence of unlimited number of elements in the periodic table the inability of atoms to align perfectly with other atoms the ability of all elements to react with every other element all elements being equally reactive
