Answer: pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

Answer:
you first get the unbalanced equation to show the various products and reactants. then, you write down the atoms in each element(quantity). add the coefficients so it's equal on both sides, and get state of matter
Explanation:
We can confirm that the velocity of an object is determined by the displacement of the object over a period of time.
<h3>How do we know that displacement and time determine velocity?</h3>
We know this by analyzing the scientific formulas created to measure the velocity of an object. The formula for this is
, meaning displacement over a period of time. Since option 3 described this equation perfectly, we can say that this is the correct option.
Therefore, we can confirm that the velocity of an object is determined by the displacement of the object over a period of time.
