The heat absorbed by the metal is 729.9 kJ.
We can calculate the heat absorbed by the copper using the formula below
⇒ Formula:
Q = cm(t₂-t₁)............... Equation 1
⇒ where:
- Q = Heat absorbed by the copper
- c = Specific heat capacity of the copper
- m = Mass of the copper
- t₁ = Initial temperature
- t₂ = Final Temperature
From the question,
⇒Given:
- m = 6.22 kg
- c of copper = 385 J/kg.°C
- t₁ = 20.5°C
- t₂ = 325.3°C
⇒Substitute these values into equation 1
- Q = 6.22×385(325.3-20.5)
- Q = 6.22×385×304.8
- Q = 729904.56 J
- Q = 729.9 kJ
Hence the heat absorbed by the metal is 729.9 kJ

Answer:
54.4 mol
Explanation:
the equation for complete combustion of butane is
2C₄H₁₀ + 13O₂ ---> 8CO₂ + 10H₂O
molar ratio of butane to CO₂ is 2:8
this means that for every 2 mol of butane that reacts with excess oxygen, 8 mol of CO₂ is produced
when 2 mol of C₄H₁₀ reacts - 8 mol of CO₂ is produced
therefore when 13.6 mol of C₄H₁₀ reacts - 8/2 x 13.6 mol = 54.4 mol of CO₂ is produced
therefore 54.4 mol of CO₂ is produced
Answer:
Explanation:
To find molecules, we will need to multiply the number of moles of carbon monoxide by Avogadro's number. Avogadro's number is .
So the equation would look like this:
