Answer: 1 molecule of 
reacts with 1 molecule of 
to give 2 molecules of HCl.
1 mole of reacts with 1 mole of to give 2 moles of HCl.
Explanation:
The given balanced reaction is:
On the particulate level :
1 molecule of reacts with 1 molecule of to give 2 molecules of HCl.
On molar level:
1 mole of reacts with 1 mole of to give 2 moles of HCl.
Aluminum's outer electron in 3p-orbital is slightly further from the nucleus and protected by 3s-orbital. This causes it to need less energy. Magnesium's outer electron is closer and not protected by an outer orbital.
Hope This Helps and Ged Bless!
There are a number of ways to express concentration
of a solution. This includes molarity. Molarity is expressed as the number of
moles of solute per volume of the solution. The concentration of the solution
is calculated as follows:
Molarity = 2.0 mole / L solution
<span>2.0 mole / L solution ( 0.50 Liters ) = 1 mole solute</span>
<span>The correct answer is the third option. One mole of solute needed to make 0.50 liters of 2M solution.</span>
Avagadro's number is just a measurement. One mole is 6.022 X 10^23 of anything - atoms, molecules, marbles... anything.
<span>1) If one mole = 6.022 X 10^23, then 8.00mol of H2S is: </span>
<span>(3.00mol H2S) (6.022 X 10^23 molecules H2S / 1 mol H2S) = 1.8060 X 10^24 molecules H2S. </span>
<span>Rounded to 3 sig figs =1.81 X 10^24 molecules H2S
</span>part2.
<span> This one uses moles in the stoichiometric sense as well as the measurement. One formula unit of MgCl2 contains 1 mole Mg and 2 moles Cl. </span>
<span>First, figure out how many moles of formula units there are. </span>
(1.81 X 10^24 FU's) (1mol MgCl2 / 6.022 X 10^23 FU's) = 3.0056mol MgCl2.
<span>Now, we know that there are 2 moles of Cl in every mole of MgCl2 (2 Cl atoms in every unit of MgCl2). From this we can determine how many moles of Cl atoms there are: </span>
<span>(3.0056mol MgCl2) (2mol Cl atoms / 1mol MgCl2) = 6.0112mol Cl atoms. </span>
<span>Now round to 3 sig figs = 10.0mol Cl atoms</span>
