The stronger the intermolecular forces, the _______the energy needed to separate the molecules, the ____________the boiling poin
slamgirl [31]

Answer:

higher, higher

Explanation:

It takes more energy to rip apart stronger bonds (that's mostly just common sense there). The boiling point increases because it would take more energy to get the molecules to go from a stuck together liquid, to separating in a gaseous form.

Complete combustion of 8.10 g of a hydrocarbon produced 25.9 g of CO2 and 9.27 g of H2O. What is the empirical formula for the h
balu736 [363]

CxHy     +  O2    -->    x CO2     +    y/2  H2O

 

Find the moles of CO2 :     18.9g  /  44 g/mol   =    .430 mol CO2   = .430 mol of C in compound

Find the moles of H2O:      5.79g / 18 g/mol     =     .322 mol H2O   = .166 mol of H in compound

 

Find the mass of C and H in the compound:

                             .430mol  x 12  =  5.16 g C

                              .166mol  x 1g   = .166g H   

 

When you add these up they indicate a mass of 5.33 g for the compound, not 5.80g as you stated in the problem.

Therefore it is likely that either the mass of the CO2 or the mass of H20 produced is incorrect (most likely a typo).

In any event, to find the formula, you would take the moles of C and H and convert to a whole number ratio (this is usually done by dividing both of them by the smaller value).

Predict the direction in which the equilibrium will lie for the reactionC6H5COO- + HF C6H5COOH + F-.Ka(C6H5COOH) = 6.5 x 10-5; K
Llana [10]

Answer:

Equilibrium will lie to the right.

Explanation:

K_{a}(HF)> K_{a}(C_{6}H_{5}COOH)

That means HF is stronger acid than C_{6}H_{5}COOH.

Alternatively, it can be said that C_{6}H_{5}COO^{-} is a stronger base than F^{-}.

Therefore HF readily gives proton to C_{6}H_{5}COO^{-} to form C_{6}H_{5}COOH and F^{-} than the reverse reaction.

So, the equilibrium will lie more towards the right i.e. towards formation of C_{6}H_{5}COOH and F^{-}.
