The units for measuring ions, molecules or atoms are called moles. Water decomposes to form hydrogen and oxygen as follows:
![\rm 2 \;H_{2}O \rightarrow 2 \;H_{2} + O_{2}](https://tex.z-dn.net/?f=%5Crm%202%20%5C%3BH_%7B2%7DO%20%5Crightarrow%20%202%20%5C%3BH_%7B2%7D%20%2B%20O_%7B2%7D)
Moles of hydrogen produced will be:
Option C. 12.6 mol
The moles can be estimated as:
- The molar ratios can be written as:
2 mol
: 2 mol
: 1 mol ![\rm O_{2}](https://tex.z-dn.net/?f=%5Crm%20O_%7B2%7D)
- The proportions and theoretical values are written as:
Let the moles of
= X
Then,
![[\dfrac {2 \text{mol H}_{2} }{1 \text{mol O}_{2}} ] = \dfrac {\text{X mol H}_{2}}{ 6.28\; \rm mol \;\rm O_{2}}]](https://tex.z-dn.net/?f=%5B%5Cdfrac%20%7B2%20%5Ctext%7Bmol%20H%7D_%7B2%7D%20%7D%7B1%20%5Ctext%7Bmol%20O%7D_%7B2%7D%7D%20%5D%20%3D%20%5Cdfrac%20%7B%5Ctext%7BX%20mol%20H%7D_%7B2%7D%7D%7B%206.28%5C%3B%20%5Crm%20mol%20%5C%3B%5Crm%20O_%7B2%7D%7D%5D)
From this it can be depicted that hydrogen produced is double compared to oxygen produced.
Solving further for X:
![\begin{aligned}\rm X &= \dfrac {6.28 \text{mol O}_{2} \times \text{2 mol H}_{2} }{ 1 \text{mol O}_{2}} \\\\&= 12.56 \;\text{mol O}_{2}\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%5Crm%20X%20%26%3D%20%5Cdfrac%20%7B6.28%20%5Ctext%7Bmol%20O%7D_%7B2%7D%20%5Ctimes%20%20%5Ctext%7B2%20mol%20H%7D_%7B2%7D%20%7D%7B%201%20%5Ctext%7Bmol%20O%7D_%7B2%7D%7D%20%5C%5C%5C%5C%26%3D%2012.56%20%5C%3B%5Ctext%7Bmol%20O%7D_%7B2%7D%5Cend%7Baligned%7D)
Therefore, 12.56 moles are produced of hydrogen.

Answer:
Though soil pH generally ranges from 1 to 14, the optimum range for most agricultural crops is between 5.5 and 7.5. However, some crops have adapted to thrive at soil pH values outside this optimum range.
Answer: all atoms of the same element have the same atomic number.
Explanation:
atomic mass differentiates them, which is the same as the mass number.
Answer:
A.
Explanation:
It would be A. because the question is asking how the harmful chemicals have an effect on the environment. This answer also proves that even though we don't mean to harm the environment it still happens because we are using these chemicals for things in our daily life.
A stationary front doesn't move at all, where warm and cold fronts do.
