58kg
Explanation:
Given parameters:
Mass of bicycle = 8kg
Total force exerted = 191.4N
Acceleration = 2.9m/s²
Unknown:
Naomi's mass = ?
Solution:
Force is a product of mass and acceleration as sated in the second law of newton.
Force = mass x acceleration
Total force on the bicycle = total mass x acceleration
191.4 = (8 + k) 2.9
8 + k = 
= 66
K = 66 - 8 = 58kg

They combine with oxygen atoms, I think.
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.
