C2H6 + O2 ⟶ CO2 + H2O Given the unbalanced equation for the combustion of ethane(C2H6), if 135 g of ethane burned, how many moles of ethane were burned?

Calculate the molarity of the solution. 6.02 x 1022 molecules of hci (molecular weight = 36.5 g/mole) in 2.0 liters of water m

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

What are the two major rules associated with polarity
