Calculate the change in energy when 75.0 grams of water drops from 31.0C to 21.6C.

Describing intermolecular forces use the drop down menus to match the type of intermolecular force to its name dipole dipole interactions dipole induced dipole interactions london dispersion forces hydrogen bond van der waals forces done

How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o c?

I'm learning about the periodic tables and what each subject's configuration is. for example, hydrogen is 1s^1, but i don't understand how you get that. can someone me understand how to figure out how to figure this out? sorry if the question makes no sense, but it would really a lot if you could me understand! you so much if you can!
