It is a simple stoichiometry problem. We have been given with balanced equation and 5.00 moles of HCl and have to calculate the moles of H2.
<span>From the balanced equation it is being clear that 2 moles of HCl are produced by 1 mole of H2. so, 1 mole of HCl will be produced by 1/2 moles of H2. So, the mole ratio of H2 and HCl is 1:2 </span>
<span>to calculate the moles of H2 for the given moles of HCl, multiply the moles of HCl by the mole ratio of H2 and HCl. </span>
<span>5.00 mole HCl x (1 mole H2/ 2 mole HCl) </span>
<span>= 2.50 mole H2 </span>
<span>so, to produce 5.00 moles of HCl, 2.50 moles of H2 are required.</span>
Answer:
The increase in electrons and the increase in the rings or clouds that the electrons are found in
Explanation:
Answer:
C.
Water has a greater density than alcohol.
Explanation:
From the experiment, it can be shown that water has a greater density than the alcohol.
The ice cube is able to float in the water because, the density of the ice is less than the density of the water.
Density of ice < Density of water
So, the ice cube sinks in alcohol because the density of the ice cube is greater than the density of the alcohol.
Density of ice > Density of alcohol
Therefore, we can assume that since the density of ice is greater than density of alcohol, then the density of water is greater than that of the alcohol.
Answer:
F' = 3 N
Explanation:
Given that,
Two objects of equal mass have a force of gravity of 6 N between them.
If the mass of one is cut in half and the other stays the same such that,
m₁' = m₁ and m₂' = (m₂/2)
We need to find the new force. The gravitational force between two objects is given by :
We have, F = 6 N
New force,
So, the new force becomes 3 N.
