Answer:

A sprinter consumes more oxygen than a marathon runner.

Explanation:

A sprinter requires big amounts of air in a short time to not get tired as fast and run faster. A marathon runner has more controlled and paced breathing so he does not get tired but can run long distances. Marathon runners also run slower than sprinters.

Answer:

Some major differences

As you burn more calories in a longer distance event, the marathon runners will need higher levels of carbohydrate than sprinters. ... Marathon runners will also use stores of body fat more to fuel their longer distances, although this can't be used without carbohydrate.

QUESTION 21 The combustion of ammonia in the presence of excess oxygen yields NO 2 and H 2O: 4 NH 3 (g) 7 O 2 (g) 4 NO 2 (g) 6 H
Harrizon [31]

Answer:

The answer to your question is 47.44 g of Oxygen

Explanation:

Data

mass of Ammonia = 14.4 g

mass of Oxygen = ?

Balanced chemical reaction

                 4NH₃  +  7O₂  ⇒  4NO₂  +  6H₂O

Process

1.- Calculate the molar mass of Ammonia

NH₃ = 4[(1 x 14) + (3 x 1)] = 4[14 + 3] = 4[17] = 68 g

2.- Calculate the molar mass of Oxygen

O₂ = 7[16 x 2] = 7[32] = 224 g

3.- Use proportions to calculate the mass of Oxygen

                     68g of NH₃ --------------------- 224 g of O₂

                      14.4 g of NH₃ -----------------  x

                       x = (14.4 x 224) / 68

                       x = 3225.6/ 68

                       x = 47.44 g
