Question

question 16 (multiple choice worth 3 points) (d1 c3r mc) if a forensic scientist is trying to identify a specific type of white powder, what is one chemical test they might do? add powder to water to check solubility conduct a flame test that requires igniting a small amount of the powder. examine the structure of the powder under a microscope calculate the density of the powder by adding it to acetone

Explanation:

A flame test is a chemical test. When a substance is ignited, the electrons in its atoms get excited. As they return to their ground state, they emit light of specific wavelengths (colors) which can help identify the substance. Checking solubility (physical property), examining structure under a microscope (physical/structural property), and calculating density (physical property) are not chemical tests.

Answer:

B. Conduct a flame test that requires igniting a small amount of the powder.
