Carbon monoxide gas reacts with hydrogen gas to form methanol via the following reaction:
CO(g) + 2H2(g) →CH, OH(g)

A 2.00 L reaction vessel, initially at 305 K, contains
carbon monoxide gas at a partial pressure of 232
mmHg and hydrogen gas at a partial pressure of 396
mmHg.

Identify the limiting reactant and determine the theoretical yield of methanol in grams.

Express your answer with the appropriate units.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
