C: 0.012 mol.
<h3>Explanation</h3>Start with 0.0020 moles of iodate ions .
How many moles of iodine will be produced?
converts to
in the first reaction. The coefficient in front of
is three times the coefficient in front of
. In other words, each mole of
will produce three moles of
. 0.0020 moles of
will convert to 0.0060 moles of
.
How many moles of thiosulfate ions are required?
reacts with
in the second reaction. The coefficient in front of
is twice the coefficient in front of
. How many moles of
does each mole of
consume? Two. 0.0060 moles of
will be produced. As a result,
moles of
will be needed.
Answer:
36.92 mg of oxygen required for bio-degradation.
Explanation:
Mass of benzene = 30 mg = 0.03 g (1000 mg = 1 g )
Moles benzene =
According to reaction 5 moles of benzene reacts with 15 moles of oxygen gas.
Then 0.0003846 mol of benzene will react with:
of oxygen gas
Mass of 0.0011538 moles of oxygen gas:
0.0011538 mol × 32 g/mol = 0.03692 g = 36.92 mg
36.92 mg of oxygen required for bio-degradation.
Answer:
<h2>14.85 moles </h2>Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>14.85 moles</h3>Hope this helps you
