Explanation:
Convection requires a fluid material that can move around. Typically, metals are solid, not fluid, and therefore do not participate in convection. ... This means that metal can be either a good heat shield, a mediocre heat shield, or a bad heat shield, depending on how we use it.
Answer:
b
Explanation:
even if the skunks are gone it doesn't affect the population of the coyote
Chemical reactions are in equilibrium when there is no net change in the reactants or products.
Chemical equilibrium refers to the situation in a chemical reaction where both the reactants and products are present in concentrations that have no further tendency to change over time, preventing any discernible change in the system's properties. When the forward reaction and the reverse reaction go forward at the same speed, this condition results. The forward and backward reactions typically have equal, if not zero, reaction rates. As a result, the concentrations of the reactants and products do not fluctuate much, indicating that the chemical reaction is in equilibrium.

She could divide a set distance by the time it takes the snail to move that distance.
Answer : The concentration of NO is, ![6.8\times 10^{-3}M](https://tex.z-dn.net/?f=6.8%5Ctimes%2010%5E%7B-3%7DM)
Solution : Given,
Concentration of
and
= 152 M
Equilibrium constant,
= ![2.0\times 10^{-9}](https://tex.z-dn.net/?f=2.0%5Ctimes%2010%5E%7B-9%7D)
The given equilibrium reaction is,
![N_2(g)+O_2(g)\rightleftharpoons 2NO(g)](https://tex.z-dn.net/?f=N_2%28g%29%2BO_2%28g%29%5Crightleftharpoons%202NO%28g%29)
The expression of
will be,
![K_c=\frac{[NO]^2}{[N_2][O_2]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BNO%5D%5E2%7D%7B%5BN_2%5D%5BO_2%5D%7D)
Now put all the given values in this expression, we get:
![2.0\times 10^{-9}=\frac{[NO]^2}{152\times 152}](https://tex.z-dn.net/?f=2.0%5Ctimes%2010%5E%7B-9%7D%3D%5Cfrac%7B%5BNO%5D%5E2%7D%7B152%5Ctimes%20152%7D)
![[NO]=6.8\times 10^{-3}M](https://tex.z-dn.net/?f=%5BNO%5D%3D6.8%5Ctimes%2010%5E%7B-3%7DM)
Therefore, the concentration of NO is, ![6.8\times 10^{-3}M](https://tex.z-dn.net/?f=6.8%5Ctimes%2010%5E%7B-3%7DM)
