Answer:

C. Theories have been confirmed through tests; hypotheses haven't.

Explanation:

In simple terms,<u> a theory is something that has been studied, tested, and validated with results</u> whereas <u>a hypothesis is when one "guesses" or "assumes" about something with no prior tests</u>. In short, a hypothesis can be best understood as just a proposal while theory can be taken as a validated result.

Through various trials and tests, a theory arrives whereas a hypothesis can be the initial stage of the testing. For example, in saying that "My hypothesis is that this metal cannot bend" is just assuming or expressing one's opinion. But when the metal is tested and a definite result is found, then that becomes a theory.

So, we can say that a theory is a confirmed result after tests while a hypothesis is not tested or confirmed with a definite result.  

Thus, the <u>correct answer is option C. </u>

Ethylenediamine (en) forms an octahedral complex with Ni2+(aq) with the formula [Ni(en)3]2+. Ni2+(aq) + 3 en ⇌ [Ni(en)3]2+(aq) K
yawa3891 [41]

Answer:

3.125\times 10^{-19} mol/L is the concentration of Ni^{2+}(aq) in the solution.

Explanation:

Ni^{2+}(aq) + 3 en\rightleftharpoons [Ni(en)_3]^{2+}(aq)

Concentration of nickel ion = [Ni^{2+}]=x

Concentration of nickel complex= [[Ni(en)_3]^{2+}]=\frac{0.16 mol}{2 L}=0.08 mol/L

Concentration of ethylenediamine = [en]=\frac{0.80 mol}{2 L}=0.40 mol/L

The formation constant of the complex = K_f=4.0\times 10^{18}

The expression of formation constant is given as:

K_f=\frac{[[Ni(en)_3]^{2+}]}{[Ni^{2+}][en]^3}

4.0\times 10^{18}=\frac{0.08 mol/L}{x\times (0.40 mol/L)^3}

x=\frac{0.08 mol/L}{4.0\times 10^{18}\times (0.40 mol/L)^3}

x=3.125\times 10^{-19} mol/L

3.125\times 10^{-19} mol/L is the concentration of Ni^{2+}(aq) in the solution.
