Thio breaks disul- fide bonds by adding extra hydrogen atoms to the two sulfur atoms joined in the disulfide bond. Neutralization, with an oxidizing agent, rebuilds the disulfide bonds by adding oxygen to the extra hydrogen atoms to form water.

If you mix a 25.0mL sample of a 1.20m potassium sulfide solution with 15.0 mL of a 0.900m basium nitrate solution and the reacti
ddd [48]

Answer:

Limiting reagent: barium nitrate

Theoretical yield: 2.29 g BaS

Percent yield: 87%

Explanation:

The corrected balanced reaction equation is:

K₂S + Ba(NO₃)₂ ⇒ 2KNO₃ + BaS

The amount of potassium sulfide added is:

(25.0 mL)(1.20mol/L) = 30 mmol

The amount of barium nitrate added is:

(15.0mL)(0.900mol/L = 13.5 mmol

Since the reactant react in a 1:1 molar ratio, barium nitrate is the limiting reagent. If all of the limiting reagent reacts, the amount of barium sulfide produced is:

(13.5 mmol Ba(NO₃)₂)(BaS/Ba(NO₃)₂ ) = 13.5 mmol BaS

Converting this amount to grams gives the theoretical yield of BaS (molar mass 169.39 g/mol).

(13.5 mmol)(169.39 g/mol)(1g/1000mg) = 2.29 g BaS

The percent yield is calculated as follows:

(actual yield) / (theoretical yield) x 100%

(2.0 g) / (2.29 g) x 100% = 87%

Two shopping carts are pushed with the same force. One cart has a larger mass than the other. How does the mass of the shopping
Harman [31]
This would problem will be answered using the concept of momentum. Momentum is the mass times the velocity, where mass is inversely proportional to the velocity. This would mean that an object with greater mass will travel at a much lesser velocity, or vice versa.

Hence, the cart with the smaller mass will accelerate faster.
