Answer:

Difference between Homogeneous mixture and Heterogeneous Mixture are as follows:

A mixture or sample that is consist of uniform composition and properties is called a homogeneous mixture while a mixture or sample that is consist of different composition and properties is called a heterogeneous mixture.
Homogenous mixture has only single phase while heterogeneous mixture has two or more phases.
Homogenous mixture can not be separated by physical methods while heterogeneous mixture can be separated out physically.
Example of homogenous mixture is Water and sugar and heterogeneous mixture is oil and water.

How might scientific knowledge about monoculture farming affect societal decisions? Please be sure to answer in complete sentenc

alisha [4.7K]

Answer:

in monoculture farming , we produce a single species of a livestock or plant in large quantity.

Even though it is very effective, producing a mass number of a single organism in an Area will risk of endangering the existence of a specific nutrient ( because that large number of organism is basically eating the same thing)

which lead to societal decision such as the founding of The Livestock conservancy, or other environmental protection organization

Pure carbon dioxide (PCO2 = 1 atm) decomposes at high temperature. For the reaction system 2 〖CO〗_2 (g) ⇌2 CO(g)+ O_2 (g) Is thi

julia-pushkina [17]

Answer:

The reaction decomposes more as T increases, therefore it is ENDOTHERMIC, meaning it requires energy to form CO and O₂.

Kp for each specie...

Kp = CO^2 O2 / (CO2)^2

for

T = 1500

Assume 1 atm for CO2, after % dissociation

P-CO2 left = 1*(1-0.048/100)= 0.99952

P-CO formed = 1-0.99952 = 0.00048

P-O2 = (1-0.99952)/2 = 0.00024

so..

Kp = CO^2 O2 / (CO2)^2

Kp = (0.00048^2)(0.00024) / (0.99952^2) = 5.53*10^-11

T = 2500

Assume 1 atm for CO2, after % dissociation

P-CO2 left = 1*(1-17.6/100)= 0.824

P-CO formed = 1-0.824= 0.176

P-O2 = (1-0.176)/2 = 0.088

so..

Kp = CO^2 O2 / (CO2)^2

Kp = (0.176^2)(0.088) / (0.824^2) =0.0040

T = 3000

Assume 1 atm for CO2, after % dissociation

P-CO2 left = 1*(1-54.8/100)= 0.452

P-CO formed = 1-0.452= 0.548

P-O2 = (1-0.452)/2 = 0.274

so..

Kp = CO^2 O2 / (CO2)^2

Kp = (0.548^2)(0.274) / (0.452^2) =0.4027
