Answer:
Car oil and vegetable oil will mix well with gasoline
Car oil and vegetable oil will not mix with water.
Explanation:
Car oil and vegetable oil will mix well with gasoline
Car oil and vegetable oil will not mix with water.
This is because of the rule of solubility. According to this rule, like substances will only dissolve like substances. In essence, a polar compound will only dissolve another polar compound. A non-polar compound will dissolve only in a non-polar solvent.
Water is polar and oil is non-polar. The cannot mix.
Gasoline is non-polar and will dissolve oil which is also non-polar .
Answer:
KOH
Explanation:
Chemical reaction:
2K + 2H₂O → 2KOH + H₂
Element ratio of K.
K = 1
Because only potassium is present.
Element ratio of H₂O.
2 : 1
in water ratio of element is 2 : 1 because two hydrogen and one oxygen atom present.
Element ratio of KOH
1 : 1 : 1
in KOH elemental ratio is 1 : 1 : 1 because one potassium one hydrogen and one oxygen atom are present.
Element ratio of H₂.
2
Just two atoms of hydrogen are present.
The atomic number tells the number of protons.
I think the answer is atoms.
