Answer:

5Fe⁺² + MnO₄⁻ + 8H⁺ => 5Fe⁺³ + Mn⁺² + 4H₂O

Explanation:

Fe⁺² + MnO₄⁻ +  H⁺ => Mn⁺² + Fe⁺³ +  H₂O

5(Fe⁺² => Fe⁺³ + 1e⁻)      =>                        5Fe⁺² => 5Fe⁺³ + 5e⁻

<u>MnO₄⁻ + 5e⁻ => Mn⁺²    =>   MnO₄⁻ + 8H⁺ + 5e⁻ => Mn⁺² + 4H₂O</u>

                                      =>  5Fe⁺² + MnO₄⁻ + 8H⁺ => 5Fe⁺³ + Mn⁺² + 4H₂O

A racehorse completes the Kentucky Derby, a distance of 1.25 miles, in
forsale [732]

Answer:

D. 60.3 kilometers per hour

Explanation:

Hello,

In this case, we first compute the miles in kilometres:

1.25miles*\frac{1.60934km}{1mile} =2.012km

Then the minutes in hours:

2.00min*\frac{1h}{60min}=0.033h

Finally, the velocity:

v=\frac{2.012km}{0.033h}\\ \\v=60.3km/h

Thus, answer is D. 60.3 kilometers per hour

Best regards.

When of alanine are dissolved in of a certain mystery liquid , the freezing point of the solution is lower than the freezing poi
Kipish [7]

Answer:

The figures and parameters to answer this question are not clearly stated, so I will answer it in the closest best way I can.

Explanation:

Molality of alanine = mole / weight of solvent( kg)

= (170×1000)/(89×600)

= 3.18 molal

We know ∆ T​​​​​​f​​​​​ = K​​​​f × m

K​​​​​​f​​​​​ = ∆ T​​​​f / molality

= 7.9/3.18 = 2.48 °c.kg.mol-1

Now using the value of cryoscopic constant we calculate can't Hoff factor for Ammonium chloride.

i = ∆ T​​​​​​f /( K​​​​f × molality of NH​​​​​4​​​​Cl)

= (24.7 × 53.5 × 600) /(2.48 × 170 × 1000)

= 1.8
