Answer:
Option 1. 0.55 mol of C₄H₁₀
Explanation:
The reaction is:
2C₄H₁₀ + 13O₂ → 8 CO₂ + 10H₂O
This is a combustion reaction where carbon dioxide and water are produced.
We convert mass of produced water to moles → 50 g / 18 g/mol = 2.78 moles of water.
The stoichometry states that:
10 moles of water are made by 2 moles of C₄H₁₀
Therefore 2.78 moles of water will be made by (2.78 . 2) / 10 = 0.55 mol of C₄H₁₀
The answer is Molecule. After a pair of shared electrons orbit around the nuclei of both atoms
Answer:
249.01 g/mol

Explanation:
<u>Step 1: Define</u>
Au(CN)₂
<u>Step 2: Identify</u>
Molar Mass of Au - 196.97 g/mol
Molar Mass of C - 12.01 g/mol
Molar Mass of N - 14.01 g/mol
<u>Step 3: Find MM</u>
Molar Mass of Au(CN)₂ - 196.97 + 2(12.01) + 2(14.01) = 249.01 g/mol
Answer:
1.006 * 103
Explanation:
Add the number between 1 and 9 and add a decimal accordingly . so the answer is 1.006 multiplied by 10 raised to power 3
