Answer:
3520 g of CO₂
Explanation:
2C₂H₆ + 70₂ → 4CO₂ + 6H₂O
molar ratio of the above reaction is;
2 : 7 → 4 : 6
2 moles of C₂H₆ will form 6 moles of H₂O
Thus, 1 mole of C₂H₆ will form 3 moles of H₂O
mass of H₂O = 360 g
molecular weight of H₂O = 18 g/mol
molar mass = mass ÷ molecular weight = 360÷18 = 20 moles
Total number of moles of H₂O formed = 6 * 20 moles = 120 moles
Number of moles of C₂H₆ reacted = 120 moles ÷ 3 = 40 moles
molar ratio of C₂H₆ to CO₂ = 1 : 2
Thus, number of moles of CO₂ formed = 2 * 40 moles = 80 moles
molecular weight of CO₂ = 44 g/mol
mass of CO₂ formed = number of moles x molecular weight = 80 * 44 = 3520 g
The method that can be used to separate the mixture is chromatography.
<h3>
What is chromatography?</h3>
"Chromatography" is obtained form a Greek word which literarily means, color writing. It is a method of separation which is common in separating a mixture of pigments.
To obtain the colors used, two solvents are mixed and the sample ink is dissolved in the solvents then spotted on a thin layer and put into a TLC chamber then the chromatogram is allowed to develop.
The various components of the pigment will appear on the chromatogram and can be identified using spectrophotometry. The Rf values of each component can also be used to identify it.'

Answer:
1 and 2
Explanation:
Releasing some of the gas would reduce the amount of atoms inside the container therefore reducing pressure.
Cold temperature would slow down the particles in the container leading to fewer collisions per second which translates to less pressure
