Answer:
Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
Explanation:
The answer is A. large differences between their boiling points
Answer:
9842kJ of energy are released
Explanation:
Based on the reaction:
2 C₄H₁₀ (g) + 13 O₂ (g) → 8 CO₂(g) + 10 H₂O (g) + 5720 kJ
<em>When 2 moles of C₄H₁₀ react with 13 moles of O₂ there are released 5720 kJ of energy</em>
As molar mass of C₄H₁₀ is 58.12g/mol, moles in 200.0g of the hydrocarbon are:
200.0g C₄H₁₀ ₓ (1mol / 58.12g) =<em> 3.441 moles of C₄H₁₀</em>
<em> </em>
As 2 moles of C₄H₁₀ release 5720kJ of energy, 3.441 moles of C₄H₁₀ release:
3.441 moles C₄H₁₀ ₓ (5720kJ / 2 moles C₄H₁₀) = <em>9842kJ of energy are released</em>
