As,
5471 kJ heat is given by = 1 mole of Octane
Then,
5310 kJ heat will be given by = X moles of Octane
Solving for X,
X = (5310 kJ × 1 mol) ÷ 5471 kJ
X = 0.970 moles of Ocatne
So, 0.970 moles of Octane will liberate 5310 kJ energy. Now changing moles to mass,
As,
Moles = mass / M.mass
Or,
Mass = Moles × M.mass
Putting values,
Mass = 0.970 mol × 114.23 g/mol
Mass = 110.83 g of Octane
The subscripts indicate the number of atoms of the element immediately before it.
Answer:
The answer to your question is: CH₄ + 3/2 O₂ ⇒ CO₂ + 2 H₂O
Explanation:
Methane = CH₄
Oxygen = O
Carbon dioxide = CO₂
Water = H₂O
CH₄ + 3/2 O₂ ⇒ CO₂ + 2 H₂O
This is the balanced equation
Answer:
59.42 ×10²³ formula units
Explanation:
Given data:
Number of moles of NH4NO3 = 9.87 mol
Number of formula units = ?
Formula:
Number of formula units = moles × Avogadro number
Solution:
Avogadro number = 6.02×10²³
Number of formula units = 9.87 × 6.02 ×10²³
Number of formula units = 59.42 ×10²³ formula units
