F2 is linear - so non polar NaCl is linear so non polar CO2 is linear so non polar H20 is very polar If you know how to draw Lewis Dot structures you could see how these are polar or non polar. Since Oxygen in H2O has a "lone pair" it is not linear becaus...

Since no info is given for number of moles of NH3 or the grams, you would just use the simple formula V1/T1 = V2/T2. Just remember that all ideal gas equations need to be in Liters & Kelvins so do your conversion before equating. In this case, 23/283 = 50...

oops celcius not celcium

Just to add the the correct answer - NaCl solid - the ions are not free to move around so cannot conduct electricity that is the difference.

Hydrogen bonding can only occur between Hydrogen and N, O, or F nothing else

Cu + H2SO4 -> CuSO4 + H20 + SO2 then balance using reactant/product set up

to get Kelvins you add 273 to C NOT 297
