List three things that you can control and or measure in this experiment in chemistry lab?

There are more than three possible controls for any experiment, as a control is just a variable that something is being tested against and compared to. Three would include temperature, color, or weight - all things that may be easily controlled among a group of test subjects.

An experiment involves three types of variable:
The independent variable is the one you are investigating or that is changed. It is the one which you deliberately vary in the experiment. You should only have one independent variable.
The dependent variable is the variable which you measure to get your results. Often there is only a single dependent variable but there can be more.
All other variables must be controlled ie kept constant so they do not change the result. There are usually many control variables in an experiment.

What is the scientific term for the things you make sure don't change during a experiment?
I assume the term for something that is not changed during an experiment is called, the control. Any changes observed in the experiment, can be compare to the control, which is still be in the original form before the experiment began.
Can you use alchemy?
Anyone can use alchemy as it is not that different from chemistry. But like chemistry it has hazards so you should use caution, acquire knowledge, have emergency numbers for things such as poison control, and safety equipment. It can be performed with many instruments used in chemistry.
What comes in your mind when you hear the word chemistry?
I have a minor in chemistry as part of my bachelor's degree. While in undergraduate I tutored fellow students in inorganic, organic and biochemistry for three years, and my mother has taught high school chemistry for 35 years. Based on all of this, I would say I know a fair deal of chemistry, particularly inorganic chemistry. The real question is, what do you want to know about chemistry?
What is the difference between a control and a constant?
A control is a duplicate setup of the experiment you are performing with everything identical except for the variable that you are testing. Or, it is how the experiment would happen naturally, without you doing anything. For example, if you are testing the effects of a certain medication on humans, you give half of the subjects the medication and the other half a placebo, which is a sugar pill that has no effect. The latter group is the "control group". Their purpose is to remove the psychological effect of taking the medication from the results of the experiment, so that the only variable remaining is the actual effects of the medication. Constants are things that are kept the same for all trials, like making sure that every subject is taking a pill (and that they believe it is the medication in question, ever if it is only a placebo)
Why does carbon play such a central role in the chemistry of living things?
Carbon plays a central role in the chemistry of living things. This is because organisms either take carbon in or release it.
What is the control variable in the experiment is the?
The purpose of a control variable in an experiment is to allow the experiment to come out with accurate results. It makes it a lot easier to measure the results when different things aren't affecting it.
What system is used to to measure things in chemistry?
metric
What could go wrong in an experiment?
Many things, for example in a chemistry experiment stuff can blow up or emit toxic gasses
What is an control?
"things that the person doing the experiment changes"
A thing that represents something involved in an experiment?
A variable represents things that are involved in an experiment. The control is the variable that doesn't change regardless of the experiment.
What is a control in an experiment?
The control is what you keep the same through the whole experiment. I'm doing an experiment for a science fair this yer and its: What things can remove permanent marker from fabric. my control would be, the amount of "stuff" i use and the type or marker. hope it helps ♥
What is the scientific term for the things you make sure don't change during a experiment?
I assume the term for something that is not changed during an experiment is called, the control. Any changes observed in the experiment, can be compare to the control, which is still be in the original form before the experiment began.
How do you Compare and contrast a control and a constant?
A constant is an ingredient or part of the experiment that does not change. A control is also a required ingredient, however it can change. (this change could be MANY things depending on the experiment type.
In a scientific experiment what is the definition of a variable?
Pretty much as it is in math, something that is undefined, but in Science it needs to be defined or the experiment cant continue. Your variables are basically what you measure, what you change and your control, both positive and negative (one with a 100% percent positive result and another with a 100% negative result)
What is apprartus?
Apparatus means things or items that are needed to conduct an experiment in physical science, chemistry, biology and physics. Examples of apparatus used in chemistry are: pipettes, burettes, conical flasks, glass beakers and thermometers.
What are the uses of medicine drooper?
um. measure things like medicine, or in labs in chemistry to measure chemicals or amounts of water. For babies amounts of cough syrup, etc.
What happens to an experiment if there is no control?
many things, it can cause a serious problem leading to death or just major injuries
