Answer:
<h3>The answer is 1.71 %</h3>
Explanation:
The percentage error of a certain measurement can be found by using the formula
![P(\%) = \frac{error}{actual \: \: number} \times 100\% \\](https://tex.z-dn.net/?f=P%28%5C%25%29%20%3D%20%20%5Cfrac%7Berror%7D%7Bactual%20%5C%3A%20%20%5C%3A%20number%7D%20%20%5Ctimes%20100%5C%25%20%5C%5C%20)
From the question
actual mass = 200 g
error = 200 - 196.59 = 3.41
We have
![p(\%) = \frac{3.41}{200} \times 100 \\ = 1.705](https://tex.z-dn.net/?f=p%28%5C%25%29%20%3D%20%20%5Cfrac%7B3.41%7D%7B200%7D%20%20%5Ctimes%20100%20%5C%5C%20%20%3D%201.705)
We have the final answer as
<h3>1.71 %</h3>

BCAA supplements are commonly taken to boost muscle growth and enhance exercise performance.
They may also help with weight loss and reducing fatigue after exercise. This article contains all the most important information about branched-chain amino acids and their benefits.
<h3><u>What are purposes of Branched-chain amino acids (bcaas) ?</u></h3>
- Leucine, isoleucine, and valine are the three essential amino acids that make up the branched-chain amino acids (BCAAs).
- Since they are vital, your body cannot create them on its own and you must get them through food.
- BCAA supplements have been demonstrated to increase muscular mass, lessen muscle pain, and reduce muscle fatigue.
- They have also been used successfully in hospitals to lessen liver disease symptoms and stop or slow down muscle loss.
- However, since the majority of people consume enough BCAAs from their diets, taking supplements is unlikely to provide any further advantages.

Answer:
7.5 mol of hydrogen would be needed to consume the available nitrogen.
Explanation:
- The balanced equation of the reaction of hydrogen with nitrogen is:
<em>3H₂ + N₂ → 2NH₃</em>
it is clear that 3mol of hydrogen react with 1 mol of Nitrogen to give 2 mol of ammonia.
- firstly, we need to calculate the number of moles of both
for H₂:
number of moles = mass / molar mass = (7.00 g) / (2.00 g/mol) = 3.5 mol.
for N₂:
number of moles = mass / molar mass = (70.00 g) / (28.00 g/mol) = 2.5 mol.
<u>using cross multiplication</u>
1 mol of N₂ needs → 3 mol of H₂
2.5 mol of N₂ needs → ??? mol of H₂
∴ the number of mol of H₂ needed = (3*2.5) / 1 = 7.5 mol
So, the right choice is:
7.5 mol of hydrogen would be needed to consume the available nitrogen.
