What are the units of molar concentration, M?  

Which of the following compounds is a non-electrolyte?

What are the coefficients for the chemical equation below, once  balanced?      ___ CH3CH2CH2OH(l) + ___O2(g)

Determine the enthalpy for the following reaction, given Δ (NH3(g)) = −46.1 kJ/mol Δ (NO(g)) = 90.3 kJ/mol Δ (H2O(g)) = −241.8 kJ/mol. 4NH3(g) 5O2(g) 4NO(g) 6H2O(g)              ΔHrxn = ? kJ

Rank the following solutions and compounds from the most conductive to the least conductive.

Use the dropdown boxes to balance the reactions below.  If a coefficient is one, normally we would leave it blank.  However, for the sake of testing it will be okay to choose “1” for balancing an equation.  [A]Hg(OH)2+ [B]H3 PO4–> [C]Hg3(PO4)2 + [D]H2O
