An experiment shows that a 247 mL gas sample has a mass of 0.432 g at a pressure of 747 mmHg and a temperature of 28 degrees celcius.What is the molar mass of the gas?
That would mean it wouldn't have any electrons to give. Can anyone answer this for me as to why there are 28 electrons being transferred if hydrogen has a oxidation state of +1 meaning it doesn't have any electrons to give?
For the unbalanced equation _Al+_O2=_Al2O3. How many moles are needed to form 2.3 moles of aluminum oxide.
H2s and H20 have similar structures and their central atoms belong to the same group. Yet H2S is a gas at room temperature and H20 is a liquid. Use bonding principals to expalin why this is.
