Everything should be held constant except for one independent variable, the one thing you change. If you don't keep everything else constant, you can't determine the cause of changes in the dependent variable.
Constants are factors in an experiment that stay the same. This should not be confused with controls -- which is a standard used for comparison
The chemical composition and physical state of substances can change during an experiment.For example two reactants in solid or liquid form can react in an experiment to give a product in a gaseous form.
An experiment should be designed to answer a specific question.

You don't want a lot of the factors && different things in an experiment to be changed because if they are all changed every now and then, it will completely change the experiment.

It depends on what the chemicals are and the experiment itself. Also, it's not clear if you're asking about what the reagents are held in for storage prior to the experiment, what they are held in temporarily during the course of the experiment but before they are actually combined, or what they are held in when they are in the process of being combined.

yes,they constent extend their nest.
no one know it just is. all the time

A experiment should only have one variable.

It depends on what your experiment was. You should ask a teacher or someone that you know who has done this before.
The data should be organized and the experiment's materials cleaned?
