Answer:
Is water that is completely free (for the most part) of dissolved minerals.
Explanation:
It doesn't have most of the minerals, they can take it away by using a process called "Distillation." They boil the water to separate it from other chemical or mixtures in it. It is a process to clean the water.
Answer:
Empirical formula: CH₂
Explanation:
We need to find the empirical formula of a compound that has carbon and hydrogen.
To find the empirical formula of any compound, if we have the mass or mass percent, we should follow 3 steps:
<u>1. Calculate the moles, dividing by the atomic weight.</u>
The atomic weight for carbon and hydrogen are 12 g/mol and 1 g/mol, so, doing the division we have:
C = 85.5 / 12 = 7.125
H = 14.3 / 1 = 14.3
<u>2. Determine the number of atoms of each element in the formula</u>
To do this, we just divide the previous moles by the lowest quantity we obtain. In this case, the carbon:
C = 7,125 / 7,125 = 1
H = 14,3 / 7,125 = 2
This means we have 1 atom of carbon and 2 atoms of hydrogen.
<u>3. Write the empirical formula with the previously obtained atoms</u>
Now that we obtained the atoms of each element, we just write the empirical formula with these numbers:
C₁H₂ but we can neglect the number one so:
<h2>
Empirical formula: CH₂</h2>

To answer this item, we assume that oxygen behaves ideally such that it is able to fulfill the following equation,
PV = nRT
If we are to retain constant the variable n and V.
The percent yield can therefore be solved through the following calculation,
n = (10.5 L)/(22.4 L) x 100%
Simplifying,
n = 46.875%
Answer: 48.87%
