C5H12 8 O2 → 5 CO2 + 6H20

Chemistry
1 answer:
bulgar [2K]3 years ago
3 0

Answer:

976.8 g

Explanation:

C₅H₁₂ + 8O₂ → 5CO₂ + 6H₂0 ------------(1)

number of moles of reaction 1 can be shown as;

1 : 8 → 5 : 6

thus, 5 moles of CO₂ will form from the combustion of 1 mole of C₅H₁₂

molecular weight of CO₂ = 44 g/mol

molecular weight of C₅H₁₂ = 72 g/mol

mass of C₅H₁₂ = 320 g

number of moles of C₅H₁₂ = mass ÷ molecular weight = 320 / 72 = 4.44 moles

thus, number of moles of CO₂ formed = 5 * 4.44 = 22.2 moles

mass of CO₂ formed = 22.2* 44 = 976.8 g

Hydrogen gas, H2, reacts explosively with gaseous chlorine, Cl2, to form hydrogen chloride, HCl(g). What is the enthalpy change
Degger [83]

Answer:

-184.6 KJ/mole

Explanation:

H2(g) + Cl2(g) ------------> 2HCl(aq)    

Δ H0 rxn = Δ H0f products - Δ H0f reactants

= 2×-92.3 - (0 + 0)

= -184.6KJ/mole

H2(g) + Cl2(g) ------------> 2HCl(aq)       Δ H0rxn   = -184.6KJ/mole

As the amplitude decreases in a wave, the energy increases.
Fittoniya [83]

Answer:

False

Explanation:

The relationship between energy and amplitude can be written as eαa^2

This means that the energy of a wave is directly proportional to the square of the amplitude.
