2(C4H10)+13(O2)->8(CO2)+[](H20)
Explanation:
sorry i couldn’t get the last one
Explanation:
a law stating that the freezing and boiling points of an ideal solution are respectively depressed and elevated relative to that of the pure solvent by an amount proportional to the mole fraction of solute.
please mark me brainliest
Moles of KClO₃ = 59.3 / (39 + 35.5 + 16 x 3)
Moles of KClO₃ = 0.48
Molar ratio of KClO₃ to O₂ = 2 : 3
Moles of O₂ produced = 1.5 x 0.48
= 0.72
Mass of O₂ = moles x Mr
= 0.72 x 32
= 23.04 grams
Answer:
0.25 moles of COCl₂ are been produced
The element that is oxidized is C, it changed the oxidation state from +2 in CO to +4 in phosgene.
Explanation:
Equilibrium reaction:
Cl₂(g) + CO(g) ⇄ COCl₂(g)
Let's convert the mass of CO to moles:
7g . 1mol /28g = 0.25 moles
As ratio is 1:1, we can say that 0.25 moles of COCl₂ are been produced.
1 mol of chlorine reacts to 1 mol of carbon monoxide in order to produce 1 mol of phosgene.
Chlorine is been reduced:
Cl₂ + 2e⁻ ⇄ 2Cl⁻
Change the oxidation state, from 0 (ground state) to -1. Oxidation state decreased.
Carbon is been oxidized.
In CO, carbon has +2 as oxidation state. In phosgene the oxidation state is +4. This oxidation state was increased, that's why it has oxidized.
