9.98 g of NH₃ reacts with 23.4 g of O₂ (up to 3 significant figure).

<h3>What is Significant figures ?</h3>

The digits of a number that are used to express it to the required degree of accuracy, starting from the first non-zero digit.

The given chemical equation ;

4NH₃ + 5O₂ ---> 4NO + 6H₂O

Therefore,

4 moles of NH₃ reacts with 5 moles of O₂.

i.e,

68 g of NH₃ reacts with 160g of O₂.

Therefore,

9.98 g of NH₃ reacts with :

      = 160/68 x 9.98

      = 23.4 g of O₂ (up to 3 significant figure)

Ede4ka [16]

Answer:

The correct option is;

C. Old Age River

Explanation:

Among the three stages of  the development of a river, which are the youthful, mature, and old age stages, the old age river is least dynamic

The water is very slow moving  with a low gradient and lesser erosive power to alter the landscape which results in the appearance of flood planes

Examples of old age rivers include, lower Ganges, lower Nile, Indus, and Yellow rivers

Old age rivers are characterized by a broad shape, with a wide flood plane, a very gentle gradient and the water current is low.
