The question is incomplete, the complete question is;  

Wetlands can play a significant role in removing fertilizer residues from rain runoff and groundwater; one way they do this is through denitrification, which converts nitrate ions to nitrogen gas:

2NO_3^-(aq) + 5 CO(g) + 2 H+(aq)  N2(g) + H2O(l) + 5 CO2(g)

Supposed 200.0 g of NO_3^- flows into a swamp each day. What volume of N2 would be produced at 17 deg C. and 1.00 atm if the denitrification process were complete? What volume of CO2 would be produced? Suppose the gas mixture produced by the decomposition reaction is trapped in a container at 17 deg C; what is the density of the mixture if we assume that the total P = 1.00 atm?  

Answer:

See detailed solution below

Explanation:

First we must obtain the number of moles of NO3^- from

number of moles = mass/molar mass

mass of = 200g

molar mass of NO3^- = 62 g/mol

number of moles = 200g/62g/mol = 3.23 moles

From the reaction equation;

2 moles of NO3^- yields 1 mole of N2

3.23 moles yields 3.23 * 1/2 = 1.6 moles

From

PV = nRT

V = nRT/P

V = 1.6 * 0.082 * 290/1

V= 38 L

Then;

From the equation also;

2 moles of  NO3^-  yields 5 moles of CO2

3.23 moles of NO3^-  yields 3.23 * 5/2 = 8.1 moles

So,

PV=nRT

V = nRT/P

V= 8.1 * 0.082 * 290/1

V= 192.6 L

Lastly

The temperature of the mixture is 17 degrees Celsius and the pressure of the mixture is 1 atm

the total number of moles of both gases = 1.6 + 8.1 = 9.7 moles

Volume of the mixture = nRT/P = 9.7 *0.082*290/1 = 230.67 L

Mass of N2 = 1.6 moles * 28 g/mol = 44.8 g

Mass of CO2 = 8.1 moles * 44 g/mol = 356.4 g

Total mass of gases = 44.8 + 356.4 = 401.2 g

Density of mixture = mass/volume = 401.2g/230.67 L

Density of mixture = 1.74 g/L

How does the study of populations affect me?
densk [106]
One way in which the study of populations ( human populations - I assume) affects us is that they can help predict the population size in the future and prepare us for it. For example, if we see that the population is decreasing, a country might want to consider supporting child-bearing or immigration to avoid the problem of too many people receiving pensions but not paying taxes.

Notice that at the divergent boundary, the crust is experiencing tensional stress, which is causing a normal fault that results
Paladinen [302]

Answer:

In a divergent plate boundary, two plates move away from one another. Due to this divergent movement of plates, seafloor spreading takes place in the ocean basin along the mid-oceanic ridge and rifting take place in the continental areas. Due to the stretching of the crust, the lithosphere becomes thin, and with more progressive spreading, it results in the eruption of magma at the seafloor. This magma is basaltic in nature, that reaches the surface due to the force exerted by the uprising magma forming convection cells in the mantle. This type of plate motion results in the expansion of the ocean basin and the rift valley in the continental areas forms seas and oceans with increasing time.

The rocks that are formed at the mid-oceanic ridge are the youngest as the magma cools and solidifies very rapidly here. With further moving away from this spreading center the age of the rocks increases.

The divergent plate boundaries are also responsible for the occurrence of deep-focus earthquakes, and it also leads to the formation of volcanoes in its adjacent sides.
