What is a variable in chemistry?
A variable is something that is being changed purposely, to observe what effects changing it has on the substance, reaction, etc. For example, if one were to test the effects of less or more water on plants, the amount of water could be called a variable.
How do you determine which variable is your independent variable and which is you dependent variable in chemistry?
The dependent variable is located on the Y axis. The independent variable is located on the X. The dependent variable changes in response to the independent variable changing, while the independent variable is the variable that is purposefully changed in an experiment. It's easy to remember -I-ndependent, -I- change.
A variable is an unknown, so algebra equations contain them. there are lots of different ways you can see a variable though whether it be in chemistry physics , business or just a math course. They can be huge equations or just simple ones. But there will be an unknown. Usually denoted as a "x" or "y" etc For example 4x+3y^2+10x-2y+8x
