6.75 moles of H₂
Explanation:
We have the following balanced chemical reaction:
Mg + 2 HCl → MgCl₂ + H₂
From the chemical reaction we deduce that if 1 mole of Mg is reating with 2 moles of HCl then 8.30 moles of Mg is reaction with 16.60 moles of HCl, quantity which is over our available 13.5 moles of HCl. The limiting reactant is HCl.
Knowing this we devise the following reasoning:
if 2 moles of HCl produces 1 mole of H₂
then 13.5 moles of HCl produces X moles of H₂
X = (13.5 × 1) / 2 = 6.75 moles of H₂

The way how <span>data is not actually obtained from the experiment represented in a line graph is defnitely that </span><span>a colored line with a broken line. It is a well known fact that to obtain the actual data from the experiment you there should be plotted points on the line. Hope it will help you! Regards.</span>
there's no picture here but I guess the answer would be:
considering the constant temperature, if you double the volume, the pressure would be halved.
like: volume is 2, pressure is 4
if 2×2, then:4÷2
water <span>t because washing with sulfuric acid wouldn't actually get any
of the acid off of you, same with oil, just soothe it momentarily and
stop burning of the skin by creating a barrier to the acid. If you wash
with soap
it will burn even more by activating some enzymes in the acid (depending
on kind of acid) so washing with water is most practical because it
gets all of the acid off immediately to stop more burns from occurring. I
would recommend washing with water and then pouring oil onto the burn,
to create a barrier. </span>
