Answer:
Highest: Exosphere: 700 to 10,000 km (440 to 6,200 miles)
Thermosphere: 80 to 700 km (50 to 440 miles)
Mesosphere: 50 to 80 km (31 to 50 miles)
Stratosphere: 12 to 50 km (7 to 31 miles)
Lowest: Troposphere: 0 to 12 km (0 to 7 miles)
Explanation:
Answer:
1.Ecologists often estimate the size and density of. populations using quadrats and the mark-recapture method.
2. The two key components of ecosystem stability are resilience and resistance.
3.The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) affect population
4. When the climate is changing in the colder direction it effects the planet in the opposite way than it does when it is changing in the warmer direction. Ad nauseam the contemporary, it’ll keep getting hotter and at a greater rate so the ecosystem is going to die.
Answer : The unknown gas is, NO
Solution :
According to the Graham's law, the rate of effusion of gas is inversely proportional to the square root of the molar mass of gas.
or,
..........(1)
where,
= rate of effusion of unknown gas = 31.50 mL/min
= rate of effusion of gas = 30.50 mL/min
= molar mass of unknown gas = ?
= molar mass of gas = 32 g/mole
Now put all the given values in the above formula 1, we get:
From the this we conclude that the unknown gas is, NO that has 30.0 g/mol molar mass.
Hence, the unknown gas is, NO
It is important to remember that when you balance reactions that number of atoms for each substances is the same in the reactants and the products side. Therefore, the balanced chemical reaction is

The coefficiens are 1:2:1:1. Hope this answers the question. Have a nice day.</span>
