Question

1. what makes something inorganic? *

it usually contains carbon and hydrogen
it contains hydrogen
it has more than one element
it does not usually contain carbon and hydrogen

Explanation:

To determine what makes something inorganic, we recall the definition of inorganic compounds. Inorganic substances typically do not contain both carbon and hydrogen (unlike organic compounds which are based on carbon - hydrogen bonds).

• The first option is incorrect because containing carbon and hydrogen is a characteristic of organic compounds.
• The second option is incorrect as the presence of hydrogen alone does not define a substance as inorganic (e.g., hydrocarbons are organic and contain hydrogen).
• The third option is incorrect because having more than one element is not the defining feature of inorganic substances (many organic compounds also have more than one element).
• The fourth option correctly states that inorganic substances do not usually contain carbon and hydrogen.

Answer:

D. It does not usually contain Carbon and Hydrogen
