<u>Answer:</u>
5
<u>Explanation:</u>
We know that,
number of count of cardinals = 75; and
measured area = 15 square kilometers.
To find the population density of the cardinals in an area of 15 square kilometers, we need to divide the number of cardinals by the given unit area:
Population density of cardinals = 75 / 15 = 5
Therefore, the population density of cardinals in an area measuring 15 square kilometers is 5.

Answer:
Carbon dioxide as well as water are needed for photosynthesis.
Explanation:
Answer:Overall equation:
a)CO(g) + NO2(g) → CO2(g) + NO(g)
b)Each step is bimolecular
c)Rate=k[NO2]^2
d)NO3 is an intermediate
Explanation:
To obtain the overall rate equation we cancel out reactants and products that are the same on both sides of the both steps. This leaves us with CO(g) + NO2(g) → CO2(g) + NO(g) as the overall stoichiometric reaction equation. Each step involves the reaction of two molecules hence each step in the mechanism is bimolecular. The slow step involves the reaction of NO2 hence the rate of reaction depends on the first step of the reaction hence the rate equation shown in the answer. Intermediates only take part in elementary steps but do not appear as products or reactants. They are produced and consumed transiently. NO3 is an intermediate in this reaction.
We are given with
moles Ne = 0.0700 mol
PNe = 0.409 atm
T = 33°C
The reaction is
<span>NH4NO2(s) --> N2(g) + 2H2O(g)
</span>
P total = 3.93 atm
a) The volume of the container is
V = nRT/P = 0.07(0.0821)(33 + 273) / (0.409)
Solve for V
b)
The partial pressure of H2O is
PH2O = 3.93 - 0.409
Solve for PH2O
