To determine whether the amount of H2 in the lab is dangerous, we first need to know how much hydrogen gas is present in the room in units of percent by volume. For this particular problem, we cannot exactly determine since we do not know the total volume of the room. Hope this answers the question.
Answer: 30.72 moles of 
will be produced from 5.12 moles of glucose.
Explanation:
The balanced chemical equation for combustion of glucose is:
According to stoichiometry :
1 moles of glucose produce = 6 moles of
Thus 5.12 moles of glucose produce =
of
Thus 30.72 moles of will be produced from 5.12 moles of glucose.
Answer:
Chemical that can be mixed with another chemical to reduce the dangerous of a specific chemichal
Answer:
55
Explanation:
if you sub and I am writing it simple
Mass of solute = 35 grams
Mass of solution = mass of nacl + mass of water = 35.8 + 184 = 219.8 grams
Concentration = mass of Nacl x 100/mass of solution.
= 35x100/219.8 = 15.92%.
Hope this helps you.
