The law of constant proportion states that a chemical compound always contains its constituent elements in fixed ratio by mass. In the experiment to determine the empirical formula of magnesium oxide, magnesium is burned in oxygen, resulting in magnesium oxide. By measuring the mass of magnesium and the mass of oxygen reacted, the ratio of these two elements can be calculated. This ratio reflects the law of constant proportion, allowing the empirical formula of magnesium oxide to be determined, typically represented as MgO.
pressure did not remain constant or if the amount of gas did not remain constant.
In a scientific experiment, a control is the part of the experiment that remains constant and is used as a baseline to compare against the experimental group. It helps researchers determine the effect of the variable being tested in the experiment.
In any experiment there will be many things which we need to keep the same. For example, if we are finding out how long a chemical reaction is lasting for, we need to make sure that the ingredients and the same amounts of them are used throughout the experiment. Things we need to keep the same are called constants.
The proposed method of making magnesium carbonate can not be accomplished from solutions in water, because the solubility of calcium carbonate in water is so low that it can not furnish a sufficient concentration of carbonate ions to exceed the solubility product constant for magnesium carbonate.
In a scientific experiment that be the the constant

The law of constant proportion states that a pure chemical compound always contains exactly the same proportion of elements by mass.This information, together with the atomic masses of the elements in the compound enable scientists to determine the formula of a compound.
the difference between a constant in a graph and a constant in a experiment is that when on a graph, the constant is the thing that changes, and in a experiment it is the part that stays the same.
proportion
That depends on the experiment.
A constant variable is one that does not change during an experiment. If your experiment includes a dozen cupcakes and that number does not change throughout your experiment, the dozen cupcakes is a constant variable.
Two variables, X and Y, are said to be in direct proportion if X/Y is a constant. Equivalently, Y = cX for some constant c.
A variable in an experiment that stays the same is a constant.
It is the constant of proportionality.
The state of being in proportion.
To use constant in a science question, first know that constant in science means a variable that does not change in an experiment. Variables are the different factors that can change in an experiment. For example, a sentence that includes the science word of constant could be: For this experiment, the constant would be... and then you write the constant.
The factor that doesnt change in your experiment
