Carrie is conducting an experiment on a solution. the solution's initial ph is 3.2. then, as carrie gradually adds compound x into the solution, the ph increases to 9.8. what is compound x ?

Strong base.

Explanation:

pH may be defined as the negative logarithm of hydrogen ion concentration pH scale is used to measure the acidity or basicity of a substance. The acidic has pH less than seven where as base has a pH above seven.

Acid has the ability to release hydrogen ions and base releases hydroxyl ions in the solution. The initial pH of solution is 3.2, this indicates the solution is highly acidic. Carrie adds the substance X in the solution that increase the pH solution to 9.8, this means carry has added a base in the solution. The base release hydroxyl ions and increase the pH of the solution. The substance x might be a strong base.

Thus, the answer is strong base.

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
