How many grams of NO can be produced from the following reaction if 68.2 grams of NO2 is consumed?
3NO2(g) + H2O(l) → 2HNO3(aq) + NO(g) 1. 133 g
2. 314 g 3. 0.148 g 4. 14.8 g

Option 4. 14.8 g

Explanation:

3NO2 + H2O → 2HNO3 + NO

First let us calculate the molar mass of NO2 and NO. This is illustrated below;

Molar Mass of NO2 = 14 + (2x16) = 14 + 32 = 46g/mol

Mass of NO2 from the question = 3 x 46 = 138g.

Molar Mass of NO = 14 +16 = 30g/mol

From the equation,

138g of NO2 reacted to produce 30g of NO

Therefore, 68.2g of NO2 will react to produce = (68.2 x 30)/138 = 14.8g of NO.

Introducing a non-native animal into an area that has never been exposed to that animal can cause:

An imbalance in ecosystem dynamics.

Explanation:

In order for you to understand the ecosystem imbalance that could be caused with an introduced alien species, I will give you two examples:

If you introduce a predator into an ecosystem, said predator will consume all possible animals in its path since it has no competition for said food, which can lead to the extinction of said animal that serves as its prey, as well as the displacement of others. animals that can serve as food or that have benefited from the extinct species. If an herbivore is introduced, it will surely compete for the plants against the endemic species, which can cause the decrease of said food and the displacement or death of the native species.
