Answer:

2H2O + MnO2 + 3Ag^+-------------> MnO4^- + 4H^+ + 3Ag

Explanation:

Oxidation half equation:

2H2O + MnO2 -------------> MnO4^- + 3e + 4H^+

Reduction half equation:

3Ag^+ + 3e -------------> 3Ag

Overall redox reaction equation:

2H2O + MnO2 + 3Ag^+-------------> MnO4^- + 4H^+ + 3Ag

The hydrogen ions comes from water.

You didn't put a + charge on one of the Ag. It has to be on the left side 

2H2O + MnO2 ==> MnO4^- + 3e + 4H^+ 

Ag^+ + e ==> Ag^+ 
Those are the two BALANCED half reactions. Multiply equation 1 by 1 and equation 2 by 3 and add them.

A 28-kg child can consume a maximum of 23 children's acetaminophen tablets in an 8-h period without exceeding the safety-limit m
Nesterboy [21]

Answer:

(b)90mg/lb

Explanation:

The child can consume a maximum of 23 tablets with 80mg of acetaminophen, the total acetaminophen ingest is:

23*80=1840mg

This value is for 8 hours, 8 hours is 1/3 of one day. This means that the dose that can be consumed in 24 hours is 3 times 1840mg.

1840*3=5520mg

To obtain the maximum allowable dose in mg per pound of body weight, divide this last value by the weight of the child in pounds.

Conversion of units: 28Kg(\frac{2.20lb}{1Kg} )=61.6lb

\frac{5520}{61.6} =89.61\approx90mg/lb

What happens to a glass of sugar solution when sugar is added to it?
galina1969 [7]

Answer:

The molarity of the solution increases.

Explanation:

Molarity is the measure of the concentration of the solute in the solution. In this case, the solvent is the sugar solution and the solute is the sugar.

If sugar is ADDED to the already sugary solution, then there would be more sugar. Therefore, the sugar (solute) would increase in number.

This means that the answer is the third choice: The molarity of the solution increases.

The answer would not be the first or second choice because there isn't anything in the question that implies water. It just says sugar solution.

The answer is not the last choice because the sugar concentration does not decrease after you have added more sugar to it. It increases.
