Actually mass and weight are two different things but most people did not understand the difference between them. And they are used synonymously on the earth. Mass is the measure of the amount of matter and weight is the measure of how the force of gravity acts on the mass that is Weight = mass x force of gravity. And they are also directly proportional to each other that is also the reason both terms are used synonymously.
The balanced reaction is:<span>
Mg (s) + 2HCl (aq)
--> MgCl 2 (aq) + H 2 (g)
We
are given the amount hydrochloric acid to be used for the reaction. This will
be the starting point of the calculation.
40.0 g
HCl ( 1 mol HCl / 36.46 g HCl)
(1 mol H2 / 2 mol HCl) (2.02 g H2 / 1 mol H2) = 1.11 g H2</span>
Just LiOH, i also think Li2O + H2O = LiOH
<span>If you placed the letter g under a microscope, the image in the field would look completely inverted. So, instead of seeing a regular letter g, it would be inverted both from up to down and from left to right, so when you look at the letter under a microscope, it would no longer look like the letter g, but rather like the number 6. This would happen because of the convex lens which tends to invert, or flip images.</span>
