In the investigation "Comparing the Effects of the Products of Cellular Respiration
Marianna [84]

The solution changed color because the substances are not neutral.

<h3>pH</h3>

Chemical substances have different concentrations of the hydrogen cation, called PH.

The higher the pH, the more basic the substance, and the lower the more acidic.

Bromothymol blue is a pH indicator that changes its color according to the pH of the substance, yellow for acid, blue for basic and green for neutral.

In the case of the reactions in question, we have the release of CO2 (acid) in combustion and in cellular respiration, changing the color of bromothymol blue to yellow.

The process of making glass involves a chemical change. While a physical change describes change in the superficial properties of a substance-- like melting ice into water, or tearing up a piece of paper-- a chemical change alters the chemical makeup of the substance itself. Glass can undergo physical changes, too!

A student sets up the following equation to convert a measurement. (The ? stands for a number the student is going to calculate.
kvasek [131]

Answer:

1 cm/s

Explanation:

From the question given above,

the student is trying to convert 0.010 m/s to a number in cm/s.

Thus, we can convert 0.010 m/s to cm/s as illustrated below:

Recall:

1 m/s = 100 cm/s

Therefore,

0.010 m/s = 0.010 m/s × 100 cm/s ÷ 1 m/s

0.010 m/s = 1 cm/s

Therefore, 0.010 m/s is equivalent to 1 cm/s
