Answer:
atoms of hydrogen
Explanation:
The molecular formula for a water molecule is 
.
From the above formula, we can conclude that 1 molecule of water contains 2 atoms of hydrogen and 1 atom of oxygen.
There are 
molecules of water.
1 molecule of water = 2 atoms of hydrogen.
∴ molecules of water = 
atoms of hydrogen.
Therefore, there are atoms of hydrogen in molecules of water.
Answer:
a strong electrolyte
Explanation:
Let's look at the meaning of the following terms so we can obtain the right answer by means of elimination.
- Strong Electrolyte : A strong electrolyte is a solution/solute that completely, or almost completely, ionizes or dissociates in a solution. These ions are good conductors of electric current in the solution.
- Weak Electrolyte : A weak electrolyte is an electrolyte that does not completely dissociate in aqueous solution. The solution will contain both ions and molecules of the electrolyte. Weak electrolytes only partially ionize in water (usually 1% to 10%)
- Strong ion : Strong ions are cations and anions that exist as charged particles dissociated from their partner ions at physiologic pH. Thus, these ions are “strong” because their ionization state is independent of pH.
Strong Electrolye fits the condition and hence is the correct option.
Answer : The correct option is, (D) 
Explanation : Given,
Concentration of 
= 3 M
Concentration of 
= 1 M
Concentration of 
= 2 M
The given balanced equilibrium reaction is,
The expression for equilibrium constant for this reaction will be,
![K_{eq}=\frac{[NH_3]^2}{[N_2][H_2]^3}](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5BNH_3%5D%5E2%7D%7B%5BN_2%5D%5BH_2%5D%5E3%7D)
Now put all the given values in this expression, we get the value of 
Therefore, the value of for the given reaction is, 1.125
