HCl and Mg are two chemicals. There is no variable involved - independent or otherwise!
F=mg where g is the gravitational constant, and the independent variable in force calculations
The independent variable.
the dependent variable changes with the independent variable. the independent variable only changes when changed by the experimenter. Time is usually an independent variable.
An independent variable is a factor that doesn't rely on anything, unlike the dependent variable (which relies on the independent variable). The most common independent variable is time.
The independent variable is the variable which you change. It is not changed by any outside factors and so is independent of them.The dependent variable is the variable which is changed by the independent variable changing and which you measure. It is dependent on another variable.

co2 and oxygen even a little methane
The independent variable.
Changes in the independent variable are independent of changes in any other variable,
The independent variable.
The reaction between hydrochloric acid (HCl) and magnesium (Mg) produces magnesium chloride (MgCl2) and hydrogen gas (H2). The balanced chemical equation is 2HCl + Mg -> MgCl2 + H2.
the dependent variable changes with the independent variable. the independent variable only changes when changed by the experimenter. Time is usually an independent variable.
The Independent variable is the one you control. The dependent variable is controlled by the Independent Variable.
The independent variable of an experiment is the variable that you change, and the dependent variable is the result of the independent variable.
Math: Independent variable is what you change. Dependent variable is what you measure.
The balanced chemical equation for the reaction between HCl and Mg is: Mg + 2HCl -> MgCl2 + H2. One mole of Mg reacts with 2 moles of HCl. Calculate the moles of Mg in 5.2 grams using the molar mass of Mg. Then use the mole ratio to find the moles of HCl needed, and finally calculate the mass of HCl using its molar mass.
An independent variable is a factor that doesn't rely on anything, unlike the dependent variable (which relies on the independent variable). The most common independent variable is time.
