The absence of standards of absolute and universal application.
Answer:
Number 1 is false
Explanation:
1.- Charged molecules are insoluble in water. The statement is false, charged molecules are soluble in water and this is the main characteristic of charged molecules.
2.- Hydrophobic molecules tend to be nonpolar and hydrophilic molecules tend to be polar. This is true, hydrophobic molecules are non polar and hydrophilic molecules are polar.
3.- Gasoline has partial positive and negative charges which allows it to dissolve in water. This is true, gasoline is soluble in water.
4.- NH3 dissolves in water because its molecules form hydrogen bonds with water. This is true, NH3 interact with water because they can form hydrogen bonds.
5.- Hydrophobic molecules prefer to interact with each other in an aqueous solution. Absolutely true, hydrophobic molecules interact among them and they isolate from the environment.
Moles ratio:
<span>S + 2 H2SO4 = 3 SO2 + 2 H2O
</span>
2 moles H2SO4 ------------ 3 moles SO2
moles H2SO4 --------------- 12.5 moles SO2
moles H2SO4 = 12.5 x 2 / 3
moles H2SO4 = 25 / 3
=> 8.33 moles of H2SO4
Explanation:
As the earth rotates from west to east. So the eastern hemisphere receives the sunlight faster than the western hemisphere and when as the earth rotates on its axis time also keeps on changing from Eastern to western hemisphere. As when there will be day in eastern hemisphere the western hemisphere will have night there. and as the earth rotates it affects the day . so in this way they are related.
