<u><em>I believe the answer you are looking for is position 4 </em></u>, because the northern face of the hemisphere is facing away from the sun not getting
to much heat nor daylight therefore its cold making it winter fully in option 4.
Just a tip option 3 looks like its facing back but half of it is still shown to the sun.
Answer:
Ay high concentration of reactants
Explanation:
To slow down a reaction, you need to do the opposite. Factors that can affect rates of reactions include surface area, temperature, concentration, and the presence of catalysts and inhibitors. ... Concentration - another way to increase the rate of a chemical reaction is to increase the concentration of the reactants.

Answer:
5.88atm
Explanation:
First, we obtain the number of mole of CO2 present in the vessel. This is illustrated below:
Molar Mass of CO2 = 12 + (2x16) = 12 + 32 = 44g/mol
Mass of CO2 from the question = 345.1g
Number of mole of CO2 =?
Number of mole = Mass/Molar Mass
Number of mole of CO2 = 345.1/44
= 7.84moles
Now we can easily calculate the pressure by doing the following:
Data obtained from the question include:
V (volume) = 32.1 L
T (temperature) = 20°C = 20 + 273 = 293K
R (gas constant) = 0.0821atm*L/mole*K
n (number of mole) = 7.84moles
P (pressure) =?
We will be making use of the ideal gas equation PV = nRT to calculate the pressure
PV = nRT
P = nRT/V
P = 7.84 x 0.0821 x 293/32.1
P = 5.88atm
Therefore, the pressure is 5.88atm
