If a reaction releases 675,000 Joules, how many kcal does it release?
Mamont248 [21]

Answer: If a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.

Explanation:

According to the standard conversion,

1 Joule = 0.000239006 kcal

Therefore, 675,000 Joules will be converted into kcal as follows.

1 Joule = 0.000239006 kcal\\675,000 J = 675000 J \times \frac{0.000239006 kcal}{1 J}\\= 161.328872 kcal

Thus, we can conclude that if a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.

Good morning,

I would say your answer is B).Toxic cellular waste builds up

The urinary system, also known as the renal system, produces, stores and eliminates urine, the fluid waste excreted by the kidneys. The kidneys make urine by filtering wastes and extra water from blood. Urine travels from the kidneys through two thin tubes called ureters and fills the bladder.
