Answer:
9.1L
Explanation:
Firstly, to solve the problem, we need a balanced chemical equation.
2H2 + O2 ———> 2H2O
2 moles of hydrogen reacted one mole of oxygen. Now, we know that at STP, one mole of a gas occupies a volume of 22.4L, now let us get the number of moles in 4.55L of oxygen.
This means 4.55/22.4 = 0.203125 mole
Since in theory we have 2 moles of hydrogen reacting one mole of oxygen. Hence the number of moles of hydrogen we have is 0.203125 * 2 = 0.40625 mole
We now proceed to get the volume of hydrogen gas. Since 1 mole is 22.4L, then
0.40625 Is 0.40625 * 22.4 = 9.1L
It could be treated like a regular first aid?
B.gas would has the most kinetic enegry because its particles move freely
<span>They are the combined effects of the gravitational forces exerted by the sun and moon on the rotation of the Earth </span>
Can you get a closer picture?
