In this experiment, you will change the temperature and particle size of the antacid tablet and observe how these changes affect the reaction. write a scientific question that you will answer by doing this experiment.

The scientific questions that could be answered by this experiment are:

How does the particle size affect the rate of dissolution of the antacid?

What is the effect of changing the temperature on the rate of dissolution of the antacid?

Further Explanation:

A scientific question must be about the relationship of the dependent and independent variables in the investigation.

The independent variable is the variable that the experimenter manipulates and changes voluntarily. The dependent variable is the responding variable. It changes only in response to the manipulation that was done to the independent variable. The dependent variable is usually what is observed or measured in the experiment.

In the given investigation, the independent variables were temperature and/or particle size. For the experiment to be fair, all variables must be kept constant except the independent variable. To avoid confusion, only one independent variable is manipulated at a time. Therefore, in this experiment, either the temperature will be changed first, or the particle size. It would be confusing to change both at the same time.

The effect of the independent variables on the reaction will be observed, hence, it is the dependent variable. To narrow down which aspect of the reaction will be observed, the focus could be on the rate of dissolution or how fast the antacid dissolves.

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
