The reaction of zinc with hydrochloric acid. Zn + 2HCl → H2 + ZnCl2. In here, zinc, an element, will replace the halogen chlorine in the compound hydrochloric acid to form a hydrogen gas and zinc chloride molecule.
Ответ:
The independent variable is something that is purposely changed in order to see the effects of change on the dependent variable. So since Carl wants to measure the temperature of water at different depths we will purposely change the depth of the water in order to observe how this would affect the temperature.
Dependent variable - Temperature of the water
The dependent variable is something that is dependent on the independent variable and is assumed to change as the independent variable changes. So we can determine that the temperature of the water is the independent variable as Carl expects it to change with the depth of the water. Another reason we can determine this is the dependent variable is because Carl can change the depth of the water measured but not the temperature of the water depths.
