CaC2 (s) + 2 H2O (g) → Ca(OH)2 (s) + C2H2 (g)
The complete reaction of 57.4 g of CaC2 requires consumption of g of H2O.

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.

In general metals get as you move from left to right across the periodic table.
