In an attempt to maximize the yield of methanol (amount of methanol produced), a chemist would try to shift the equilibrium as f
MakcuM [25]

Answer:

removing the methanol as it is formed

Explanation:

One of the ways to drive the equilibrium position towards the right is to remove one of the products formed.

According to Me Chatelier's principle, the imposition of a constraint on a system in a equilibrium causes the equilibrium position to shift towards a new position that annuls the constraint. Hence, removing the methanol causes the equilibrium position to shift to the far right in order to reestablish equilibrium according to Le Chatelier's principle.

The lung capacity of the blue whale is 4900 L . Convert this volume into gallons
adell [148]
1 liter = 2.11 pints
8 pints = 1 gallon

4900 L * (2.11 pints/1 L) * (1 gallon/8 pints) = 1292.375 gallons

4900 has 2 significant figures, so our final answer should have two. Your final answer is 1300 gallons.
