Answer:
Q = 1252.82kJ
Explanation:
Mass = 179g
Initial temperature (T1) = 25°C = (25+273.15)K = 298.15K
Final temperature (T2) = 82.70°C = (82.70 + 273.15)K = 335.85K
Specific heat capacity (c) = 121.3J/g.K
Heat energy (Q) = mc∇T
M = mass of the substance
Q = heat energy
c = specific heat capacity of the substance
∇T = change in temperature of the substance = T2 - T1
Q = mc∇T
Q = 179 × 121.3 × (355.85 - 298.15)
Q = 21712.7 × 57.7
Q = 1,252,822.79
Q = 1252.82kJ
The heat energy required to heat 179g of acetic acid from 25°C to 82.70°C is 1252.82kJ
Answer:
Biphenyl
Explanation:
The reaction of bromo benzene with magnesium-ether solution yields a Grignard reagent.
The byproduct of this reaction is biphenyl. It is formed when two unreacted bromobenzene molecules are coupled together.
Hence, It is advised that the bromobenzene solution be added slowly to the magnesium-ether solution so that it isn't present in a high concentration, thus reducing the amount of biphenyl by-product formed.
Answer:
0.5 moles of O₂
Explanation:
See the stoichiometry of the reaction:
2CO + O₂ → 2CO₂
2 moles of carbon monoxide need 1 mol of oxygen to react in order to produce 2 moles of carbon dioxide.
If I want to produce 1 mol of CO₂, I just need the half of O₂.
You will see in this rule of three. Ratio is 2:1
2 moles of CO₂ are produced by 1 mol of O₂ (Stoichiometry - reaction)
1 mol of CO₂ will be produced by ( 1 . 1) / 2 = 0.5 moles
