The estimated daily basal metabolic rate for a man who weighs 150 lb is _____ kcal.
Nezavi [6.7K]
The estimated daily basal metabolic rate for a man who weighs 150 lb is 1636 kcal.
Basal metabolic rate is the rate of energy expenditure per unit time by endothermic animals at rest. Metabolism comprises the processes that the body needs to function. It is the amount of energy per unit time that a person needs to keep the body functioning at rest. Any increase to the metabolic weight, such as exercise, will increase the basal metabolic rate.

Black coffee has a pH around 5; hand soap has a pH of 10. How many times more acidic is coffee relative
Anon25 [30]

Answer:

\boxed {\boxed {\sf 10^5 \ or \ 100,000 \ times \ more \ acidic}}

Explanation:

The pH scale stands for the power or potential of hydrogen. It measures how acidic or basic a solution based on the concentration of hydrogen ions and a scale from 1 to 14.

This scale is unique because it is logarithmic. So, every time the pH changes by 1 on the scale, the actual concentration of the solution increases or decreases by a tenfold.

So, a solution with a pH of 7 is ten times more acidic than a solution with a pH of 8. This can be translated to:

10^ {difference \ in \ pH}

The black coffee has a pH of 5 and the hand soap has a pH of 10. We want to find how many times more acidic coffee is, so we subtract 5 from 10 and get 5. The difference in pH is 5.

10^5=100,000

Coffee is <u>10⁵ or 100,000 times more acidic than hand soap.</u>
