Answer:
32 mols of water
Explanation:
2H2 + O2 ==> 2H2O
What your givens are telling you and what the equation is saying is that
for every mol of O2, you get 2 mols of H2O
So you could do it with the proportion about.
1/16 = 2/x Cross multiply
x = 16 * 2
x = 32
Answer: molar mass
Explanation:
The molar mass of any substance is it's relative molecular mass expressed in grams. Hence, the relationship between molar mass of any substance and mass, in grams, of one mole of any substance is mathematically expressed as:
Number of moles =
(Mass in grams ➗ Molar mass)
Hence, the unit of molar mass is gram per mole (g/mol)
Thus, molar mass is the answer.
Answer:
b-acting as a standard unit of measure
Explanation:
No, hydrogen can only hold one bond and that's it. It only needs to be paired with one bond.
Answer:
5.55 L
Explanation:
This excersise can be solved by the Boyle's law.
This law for gases states that the pressure of a gas in a vessel is inversely proportional to the volume of the vessel.
P₁ . V₁ = P₂ . V₂
The law comes from the Ideal Gases Law, in the first term.
P . V = n . R . T In this case, n . R . T are all constant.
6.35 L . 88.6 kPa = 101.3 kPa . V₂
V₂ = (6.35 L . 88.6 kPa) / 101.3 kPa
V₂ = 5.55 L
It is inversely proportional because, as it happened in this case, pressure was increased, therefore volume decreased.
