Answer: The independent variable is the type of metal being used.
{Note: The "dependent variable" is the "measured density" that corresponds to each of the metals."}.

Explanation:
___________________________________________
The "independent variable", which is plotted on the "x-axis" (horizontal axis), is the variable that can be "controlled/manipulated". In this case, this would be the type of metal chosen.
The "dependent variable" , which is plotted on the "y-axis" (vertical axis) is the "obtained value/measurement/result" (that "cannot be controlled/manipulated").
In this case, the "density", which is the "measured value" that corresponds to the selected "meal", is the "dependent variable".

Calcium. this is because Mg and calcium is in the same group. hence, they have similar chemical properties
Cuz the match can burn and turn in to ash so when it burn and turn in to ash you can't do nothing with the ash hop that make since
