1. some powders should have given off gas bubbles upon reaction with vinegar. what is the molecular formula of this gas? a. o₂ b. h₂ c. co₃ d. co₂

Answer

Brief Explanations:

Vinegar is acetic - acid based. When some powders (such as carbonates) react with vinegar, a common gas produced is carbon - dioxide. Oxygen ($O_2$) and hydrogen ($H_2$) are not typically produced in such reactions, and $CO_3$ is not a stable gas molecule. The correct gas is carbon - dioxide.

Answer:

D. $CO_2$
