Why the southern hemisphere experiences summer when the northern hemisphere experiences winter.

Chemistry

siniylev [52]3 years ago
3 0

Answer:

Northern hemisphere and southern hemisphere are two poles of the earth that are responsible for a different environment.

Explanation:

Theses both hemispheres have different climate at its poles. This happened because of pf the tilt of the earth. on the axis. When the northern pole gets tilt towards the sun it gets to summer.

The northern poles get sarcastically hotter season. So that when the northern pole is hotter the southern pole gets cooler at that time. All has happened because the earth gets tilted towards its poles or axis.

The equilibrium constant, Kp, for the following reaction is 10.5 at 350 K: 2CH2Cl2(g) CH4(g) CCl4(g) Calculate the equilibrium p
Ostrovityanka [42]

The complete question is as follows: The equilibrium constant, Kp, for the following reaction is 10.5 at 350 K: 2CH2Cl2(g) CH4(g) + CCl4(g) Calculate the equilibrium partial pressures of all species when CH2Cl2(g) is introduced into an evacuated flask at a pressure of 0.968 atm at 350 K. PCH2Cl2 = atm PCH4 = atm PCCl4 = atm

Answer: The equilibrium partial pressures of all species, that is, CH_{4}, CCl_{4} and CH_{2}Cl_{2} is 0.420 atm, 0.420 atm and 0.128 atm.

Explanation:

For the given reaction equation, the initial and equilibrium concentration of involved species is as follows.

                       2CH_{2}Cl_{2}(g) \rightarrow CH_{4}(g) + CCl_{4}(g)\\

Initial:                0.968 atm         0               0

Equilibrium:  (0.968 - 2x)           x                x

Now, K_{p} for this reaction is as follows.

K_{p} = \frac{P_{CH_{4}}P_{CCl_{4}}}{P^{2}_{CH_{2}Cl_{2}}}\\10.5 = \frac{x \times x}{(0.968 - 2x)^{2}}\\x = 0.420

P_{CH_{4}} = x = 0.420 atm\\P_{CCl_{4}} = x = 0.420 atm\\P_{CH_{2}Cl_{2}} = (0.968 atm - 2x) = (0.968 atm - 2(0.420)) = 0.128 atm

Thus, we can conclude that the equilibrium partial pressures of all species, that is, CH_{4}, CCl_{4} and CH_{2}Cl_{2} is 0.420 atm, 0.420 atm and 0.128 atm.

How to activate biochar​
andrezito [222]

To activate biochar  take your finished compost and mix it with some water. Then add the biochar and the liquid compost soak in. For optimal results, add  a bit of sugar to the compost tea, and oxygenate it for 12 to 24 hours before adding the biochar.

Why does metal need to be extracted from an ore before it can be used?
Hunter-Best [27]
Metal ore has other elements in it as well. Also sediment and stone might cover the ore. We don't want to have a phone with sediment on it do we? thus these few reasons are why.
