The addition of hydrogen carbonate to bromothymol blue turns the solution blue. Thus, option B is correct.
The balanced equation for the dissociation of bromothymol blue is:
The color of dissociated form is yellow and undissociated form is blue.
<h3>What is the final color of solution?</h3>
The addition of hydrogen carbonate results in the dissociated ions as:
The dissociation results in the increased hydrogen ion concentration. The undissociated form in the reaction mixture increases.
Thus, the color of the solution will turn blue. Hence, option B is correct.

The average speed of the horse for the entire motion is 66.67 m/s.
The given parameters;
- <em>distance traveled by the horse, d = 1 km = 1,000 m</em>
- <em>time of motion of the horse, t = 15 s</em>
The average speed of the horse is calculated by dividing the total distance traveled by the horse by the time of motion.
The average speed of the horse is calculated as follows;
Thus, the average speed of the horse for the entire motion is 66.67 m/s.

Answer:
If 5.9 moles of CO₂ react, 5.9 moles of CuO will also react.
Explanation:
The balanced reaction is:
CuO + CO₂ → CuCO₃
By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:
- CuO: 1 mole
- CO₂: 1 mole
- CuCO₃: 1 mole
You can see that the stoichiometric relationship between CuO and CO₂ is 1: 1. In other words, for each mole of CuO that reacts, one mole of CO₂ will also react.
So <u><em>if 5.9 moles of CO₂ react, 5.9 moles of CuO will also react.</em></u>
