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
The potential energy:
E p = m · g · h
m = 25 kg, g = 9.81 m/s², h = 3 m
E p = 25 kg · 9.81 m/s² · 3 m = 735.75 J
miscible cause the clear blue liquid is a homogeneous mixture
Answer:
<h2>The advantage is that, you can add additional power devices usually using batteries.</h2>
<h2>The disadvantage is ... if one component in a series circuit fails, then all the components in the circuit fail because the circuit has been broken. </h2>
