Answer:
The circulatory system.
Explanation:
All of them are in charge of pumping blood and oxygen throughout the body, which is the job of the circulatory system.
According to the balanced reaction equation:
2KClO3→ 2KCl + 3O2
from this equation, we can see that the molar ratio between KCl & O2 is 2 : 3
so, 2 moles of KCl will need 3 moles of O2
∴ 7.16 moles of KCl will need X moles of O2
∴number of moles of O produced = 7.16 * 3 / 2
= 10.74 moles

<h3>What is Scientific Notation ?</h3>
Scientific notation is a way of writing very large or very small numbers.
A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.
<h3>Steps to Calculate Scientific Notation ;</h3>
- Determine the exponent, n , on the factor 10 .
- Move the decimal n places, adding zeros if needed.
- If the exponent is positive, move the decimal point n places to the right.
- If the exponent is negative, move the decimal point |n places to the left.
- Check.
