Name the part of the type of Quantitative Data data shown here: 50 grams of copper chloride was mixed with 100 ml of water

Qualitative Data from The aluminum foil changed shiny to lack luster

Flask 1 contained 20 grams of copper chloride and 100 ml of H 2 O Flask 2 contained 10 grams of copper chloride and 100 ml of H 2 O Flask 3 contained 30 grams of copper chloride and 100 ml of H 2 O What is the independent variable?

There were 2 grams of residue left over in flask 1. There was 1 gram of residue left over in flask 2. There was. 5 grams of residue left over in flask 3. What is the amount of Dependent Variable residue remaining called?
