Answer:

ΔH = 8.87 x 10₅

Explanation:

q = mcΔT = 20g x 1.00 cal/g°C x 10.6°C = 212 cals x 4.184 j/cals = 8.87 x 10⁵ joules

If 5g of H2 are reacted with excess CO, how many grams of CH3OH are produced, based on a yield of 86%?
Cerrena [4.2K]

Answer: 34.4 g

Explanation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

\text{Number of moles of hydrogen}=\frac{5g}{2g/mol}=2.5moles

As CO is in excess, H_2 is the limiting reagent and thus it will limit the formation of products.

CO+2H_2\rightarrow CH_3OH

According to stoichiometry:

2 moles of hydrogen produce = 1 mole of CH_3OH

2.5 moles of hydrogen produce = \frac{1}{2}\times 2.5=1.25 moles of CH_3OH

Mass of CH_3OH=moles\times {\text {Molar mass}}=1.25\times 32=40g

But as % yield is 86%, mass of CH_3OH produded is \frac{86}{100}\times 40=34.4g

Thus 34.4 g of CH_3OH is produced.
