Answer:
It is polar.
Explanation:
Water is a polar solvent and it can only dissolve another solute or substance.
As a general rule of solubility "likes dissolves likes".
This implies that when a polar solvent is used, it will dissolve a polar solute.
Also, a non-polar solute will only dissolve in a non-polar solvent.
- Water is an example of polar solute.
- Other solutes such as salt can dissolve in water because they are polar in nature.
- A non-polar solvent is oil.
Answer:
Your question is missing some information.
But in most of the systems, potential energy and kinetic energy are inversely proportional
Molar mass O2 = 31.99 g/mol
Molar mass CO2 = 44.01 g/mol
Moles ratio:
<span>C3H8 + 5 O2 = 3 CO2 + 4 H2O
</span>
5 x 44.01 g O2 ---------------- 3 x 44.01 g CO2
( mass of O2) ------------------ 37.15 g CO2
mass of O2 = 37.15 x 5 x 44.01/ 3 x 44.01
mass of O2 = 8174.8575 / 132.03
mass of O2 = 61.916 g
Therefore:
1 mole O2 ----------------- 31.99 g
moles O2 -------------------- 61.916
moles O2 = 61.916 x 1 / 31.99
moles = 61.916 / 31.99 => 1.935 moles of O2
Because it contains hydrogen which isn't formed by a special process like oxygen
