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.
potassium chloride from potassium hydroxide and hydrochloric acid
Answer: C Snow
Explanation:
Because the temperature is low and it is below freezing temperature. Sorry if I am wrong.
Answer:
4.321 x 10^-8
Explanation:
2.17 x 10^-3 = 0.00217 g
5.022 x 10^4 = 50220 mL
0.00217/ 50220 = 0.0000004320987
4.321 x 10^-8
Answer:
This question is incomplete
Explanation:
This question is incomplete, however it can be concluded that this question is testing concepts about equilibrium within a chemical reaction.
It is a rule that:
If a reactant is added, the forward reaction will be favored.
If a product is added, the reverse reaction will be favored.
The same principle can be applied if a reactant/product is taken away. The reaction will try and produce more of what is not there, and this will shift the equilibrium.
