As we know that
A<span>t STP
1 mole of any gas occupies 22.4L
so
15.7L / 22.4L/mole = 0.7moles Cl2
0.7moles x 6.022x10^23molecules/mole = 4.22x10^23molecules
hope it helps</span>
<span>Okay then I would go with choice B since fusion takes place in the sun which is a giant star.</span>
Answer:
Mixture.
Pizza is a mixture of a lot of things like dough, sauce, meat, veggies, cheese, etc.
Each of those things is a mixture of other things like proteins, starches, sugars, water, fiber, vitamins, minerals, etc.
The balanced chemical reaction is:
HC2H3O2<span> (aq) +Ba(OH)2 (aq) --> H2O (l) +Ba(C2H3O2)2
</span>
We are given the amount of HC2H3O2 to be used in the reaction. We use this amount as the starting point of our calculations.
0.432 mol HC2H3O2 ( 1 mol Ba(OH)2 / 1 mol HC2H3O2 ) = 0.432 mol Ba(OH)2 needed
Hope this answers the question.
