I don’t understand the question
The answer is false
For an ex: an ice is a solid once it's melts cuz of the heat it's a liquid but if u boil the liquid then it's at it's boiling point
Idk I'm not that really good in science sorry......
Well if anything was mixed in it would make his result different. if not, it could have changed the temperature when he mixed it. which would give him either a lower or higher answer
Answer: Fractional distillation is used to separate liquids with differing boiling points
Explanation:
Sublimation is used to separate volatile substance from a non volatile substance where volatile substance gets converted from solid to gas.
Fractional distillation is separation of a liquid mixture into fractions which differ in boiling points by means of distillation by use of a fractionating column.
Chromatography is a separation method where different rates of adsortion of different components is used to separate substances.
The volume of carbon dioxide that will be produced is 191.4 g.
Calculation:
The following is the balanced equation for the given reaction:
Fe₂O₃(s) + 3CO(g) → 2Fe(s) + 3CO₂(g),
It is obvious that when 1.0 mole of Fe2O3 reacts with 3.0 mole of CO, 2.0 mole of Fe and 3.0 mole of CO2 are produced.
Hence by using cross multiplication:
If 2.0 mol of Fe was produced with → 3.0 mol of CO₂, from stoichiometry.
Then how many moles of CO₂ are produced by 2.9 mol of Fe?
To find the answer we have a formula:
∴ The no. of moles of CO₂ produced = (3.0 mol)(2.9 mol)/(2.0 mol) = 4.35 mol.
∴ The mass of CO₂ produced = no. of moles x molar mass = (4.35 mol)(44.0 g/mol) = 191.4 g.
