Question

A student writes a chemical equation of the reaction between carbon monoxide and hydrogen.

CO2 + 2H2 -> CH3OH

How can the reaction be classified?

(a) The reaction is an example of a combination reaction as a compound separates into two

compounds.

(b) The reaction is an example of a decomposition reaction as a compound dissociates into two

compounds.

(c) The reaction is an example of a combination reaction as two compounds react to form a single

compound.

(d) The reaction is an example of a decomposition reaction as two compounds react to form

a single compound.​

Answer 1

Answer:

option c

because in a chemical reaction two or more substances combine to form single substance

Answer 2

(c) The reaction is an example of a combination reaction as two compounds react to form a single compound in the production of CH3OH.

1. Combination reaction, as evident by the name, is characterized by formation of single product from multiple reactants.
2. In the given reaction, carbon monoxide combines with hydrogen to form methanol.
3. Methanol finds application in production of fuel, organic acids, as anti-freeze etc.
4. Decomposition reaction is the reaction chemical compound breaks into multiple products.
