Type the correct answer in the box.

given:

8co + 17h2 → c8h18 + 8h2o

in this chemical reaction, how many grams of h2 will react completely with 6.50 moles of co? express your answer to three significant figures.

of h2 will react completely.

27.6  grams of H2 will react completely

Explanation:

8CO + 17H₂ → C₈H₁₈ + 8H₂O

First of all, find out the moles of CO from the reaction.

If you want to know, how many moles of H₂ will react with 6.50 moles of CO you should make a rule of three, following the equation above.

8 moles of CO __ react ___ 17 H

6.5 moles of CO ___ react __ (6.5 . 17 ) / 8 = 13.8125 moles

Now, that we have the moles we can convert them to grams.

Molar mass . moles = gram

Molar mass H₂ = 2g/m

2 g/m . 13.8125 moles = 27.6 g

6.4 cm (max) - 25 cm (min)

consider the reaction below.

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?
