nikitadnepr [17]

Answer:

See the answer below

Explanation:

Organic molecules in the form of carbohydrates are created during photosynthesis or chemosynthesis and these processes cause carbon to be removed from the atmosphere or other environment into the biosphere - the living organisms of the ecosystem.

During photosynthesis, atmospheric carbon dioxide is fixed as carbohydrates into green plants in a two-stage process that requires sunlight energy and water. The entire process can be summarized as an equation below:

6CO_2 + 6H_2O + sunlight --> C_6H_1_2O_6 + 6O_2

Instead of using water as a reactant, chemosynthetic organisms make use of high energy chemicals such as hydrogen sulfide to fix carbon dioxide in order to generate carbohydrates.

CO_2 + 4H_2S + O_2 -> CH_20 + 4S + 3H_2O

Both processes ensure that carbon dioxide moves from the environment into living organisms.

1) if I have a 30 mole sample of gas at a temperature of 120˚C, and a volume of 300 L. What is the pressure of the gas on the co
vivado [14]

Answer:

P = 3.23 atm

Explanation:

Given data:

Number of moles of gas = 30 mol

Temperature = 120°C

Volume of gas = 300 L

Pressure of gas = ?

Solution:

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

120+273.15 = 393.15 K

P × 300 L = 30 mol × 0.0821 atm.L/mol.K × 393.15 K

P = 968.33 atm. L /300 L

P = 3.23 atm
