What is the independent variable when burning magnesium?

The independent variable will be the mass of magnesium ribbon as different measurements will be taken and used for each trial. The dependant variable will be the mass of Magnesium Oxide, this is a measured variable as the mass of oxygen can be calculated and will enable us to determine the formula for Magnesium Oxide.

What are the independent and dependent variables in a chemical reaction?

Independent variable is the quantity that the Chemist causes to change. Dependent variable is the quantity that responds to the change the Chemist has caused.

How do you know which is the dependent and independent variable?

An easy way to think of independent and dependent variables is, when you’re conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.

Is magnesium a independent variable?

We want to find out the effect of acid concentration on rate of reaction, so both acid concentration and rate of reaction are variables in our investigation. In any investigation there is one variable you change deliberately so you can observe the effect of doing so. This is called the independent variable.

What is the independent variable in a reaction?

The independent variable is the factor that you purposely change or control in order to see what effect it has. The variable that responds to the change in the independent variable is called the dependent variable. It depends on the independent variable.

What are examples of dependent variables?

It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.

What was the independent variable in this reaction?

An example would be investigating whether increasing the temperature of the reactants might alter the rate of the reaction. As it is the temperature which is changing, that would be the independent variable. The changing temperature alters the rate of reaction, therefore the reaction rate is the dependent variable.

Is the mass dependent variable?

Independent Variable is the volume of the object. Dependent Variable is the mass of the object.
