Question

1. 3.17 g of sodium combines with chlorine to form 8.00 g of sodium chloride. what is the mass of chlorine in this sample of sodium chloride? (3pts)

□ 3.17 g
□ 4.83 g
□ 8.00 g
□ 11.17 g
□ 9

1. which is not a physical property? (3pts)

□ boiling point
□ physical state
□ color

Explanation:

Step1: Apply law of conservation of mass

Let $m_{\text{Cl}}$ = mass of chlorine, $m_{\text{NaCl}}$ = mass of sodium chloride, $m_{\text{Na}}$ = mass of sodium. The formula is $m_{\text{Cl}} = m_{\text{NaCl}} - m_{\text{Na}}$.

Step2: Substitute given values

$$m_{\text{Cl}} = 8.00\ \text{g} - 3.17\ \text{g}$$

Step3: Calculate the result

$$m_{\text{Cl}} = 4.83\ \text{g}$$

Physical properties are characteristics observable without changing a substance's chemical identity. Boiling point, physical state, and color are all physical properties. Since no non-physical property option is fully visible, if this is a trick question with the provided options, all listed options are physical properties; however, assuming a standard question context, if a chemical property were present it would be the answer. Based on the visible options, if we infer a missing option is intended, but with given choices, note: all shown are physical properties.

Answer:

4.83 g
