Answer:
The average speed must be 30mph so this means the car traveled for 2hrs 60/30
Answer:
Acids have a high concentration of [H⁺] ions
Explanation:
In order to know about the acids, a solution is acidic when pH < 7
As pH is lower than 7, the pOH > 7
When pH = 7, solution is neutral
When pH is greater than 7, solution is basic
pH = - log [H⁺]
pOH = - log [OH⁻]
Imagine a solution of pure HCl 0.2 M
HCl → H⁺ + OH⁻
[H⁺] = 0.2 M → pH = - log 0.2 → 0.69
pH + pOH = 14
pOH = 14 - 0.69 = 13.31
10^-pOH = [OH⁻] → 10⁻¹³°³¹ = 4.89ₓ10⁻¹⁴
In conclussion [H⁺] > [OH⁻]
Answer:
It would be higher than expected.
Explanation:
Respiration quotient (RQ) may be defined as the quantity used for the representation of the basal metabolic rate. This mainly depends on the amount of the carbon dioxide.
The respiratory quotient represents the ratio of carbon dioxide eliminated with the amount of the oxygen consumed. During stress condition, the oxygen consumption of our body increase and more carbon dioxide is exhale out from the body. This will increase the RQ.
Thus, the answer is RQ will be higher than expected.
