Answer:

64

Explanation:

Nitrogen combines directly with oxygen at very high temperatures to form nitrogen(ii) oxide. This is the reaction that occurs during lightning flashes. Atmospheric nitrogen and oxygen combines during the high temperatures obtained in lightning flashes to form nitrogen (ii) oxide.

Equation of the reaction is given below:

N(g) + O(g) ---> 2NO(g)

From the equation of the reaction, 1 mole of nitrogen gas combines with one mole of oxygen gas to produce 2 moles of nitrogen (ii) oxide.

Therefore, 2 moles of oxygen gas will react with 2 moles of nitrogen gas

Mass of oxygen gas that is 2 moles of the gas is obtained from the formula; mass = number of moles * molar mass

Molar mass of oxygen gas = 32.0 g/mol

Mass of 2 moles of oxygen gas = 2 * 32.0 = 56 g

Therefore, the mass of oxygen required in grams is 64

Would you expect endangered species to be more frequently generalists or specialists? explain your answer.
Vikki [24]
You should expect an endangered species to be more SPECIALIST. Animal species that can live in different types of environment and which can survive on different types of food are called generalist. This type of animal specie can not be easily endangered because they have high level of survival. The specialist animal species on the other hand are adapted to a narrow range of food and environment. Specialist species can be easily wipe out if there food resources is exhausted or if their habitat is destroyed.

Which pair of terms concerning the osmotic effect of a solution on red blood cells is mismatched?
QveST [7]
Even though there are no choices given in this particular question, the principle of osmosis is very easy to understand. 

When we talk about osmosis, we are referring to the movement of water from a low concentration to a higher concentration. This is different from diffusion, which talks specifically about the movement of <em>solutes</em> in the solution (from a higher concentration to a lower concentration.)

When an RBC is placed inside a <em>hypertonic </em>solution, the water inside the RBC will go out thereby shrinking the RBC.

Inside an <em>isotonic</em> solution, the RBC will remain the same because the concentrations are equal.

Inside a <em>hypotonic</em> solution, the RBC will lyse or explode because water will move from the solution going inside the RBC.
