Question

pre - lab questions:

1. what is the independent variable in this lab activity? (2 pts)
2. what is the dependent variable in this lab activity? (2 pts)

data, results, and calculations
table 1. (18 pts)

Explanation:

The lab involves flame tests for metal chlorides. Independent variable is the type of metal (since it's manipulated), dependent variable is flame color (measured/observed). Chemical formulas are derived from ionic compound naming rules (metal + nonmetal, charge balance).

Answer:

1. Type of metal used
2. The flame color

	Name of Compound	Chemical Formula	Observation(s)
B	Calcium Chloride	CaCl₂	Kinda darker than orange
C	Lithium Chloride	LiCl	Red Fire
D	Copper Chloride	CuCl₂	green Fire
E	Potassium Chloride	KCl	Alum orange light
F	Strontium Chloride	SrCl₂	Orange red
