What is the value of the equilibrium constant K ?

lorasvet [3.4K]

Answer:

K = 0.0209

Explanation:

K = $\frac{[H_{2}][I_{2}]}{[2HI]^{2}}$

K = $\frac{[4.35 x 10^{-2} ][2.79 x 10^{-2} ]}{[0.241]^{2} }$

K = 0.0208958

K = 0.0209

Answer:

$C_{54}H_{102}O_6$

Explanation:

Hello!

In this case, since the molar mass of the empirical formula is:

$MM_{empircal}=9*12.01+17*1.01+16.00=141.26g/mol$

Thus, the ratio of the molecular to the empirical formula is:

$\frac{847g/mol}{141.26g/mol} =6.0$

Thus, the molecular formula is six times the empirical formula:

$C_{54}H_{102}O_6$

Best regards!

Only 1 type of replacement occurred so it should be single replacement reaction
