The mass of water produced is 4.70 g.
<em>M</em>_r: 58.12 32.00
2C₄H₁₀ + 13O₂ ⟶ 8CO₂ + 10H₂O
<em>m</em>/g: 3.03
<em>Moles of C₄H₁₀</em> = 3.03 g C₄H₁₀ × (1 mol C₄H₁₀/58.12 g C₄H₁₀) = 0.05 213 mol C₄H₁₀
<em>Moles of H₂O</em> = 0.052 13 mol C₄H₁₀ × (10 mol H₂O/2 mol C₄H₁₀) = 0.2607 mol H₂O
Mass of H₂O = 0.2607 mol H₂O × (18.02 g H₂O/1 mol H₂O) = 4.70 g H₂O
Each mole of C₂H₄ requires 3 moles of O₂ to react.
5.75 moles of C₂H₄ will require:
3 x 5.75 = 17.25 moles
Each mole of gas occupies 22.4 L at STP.
Liters of gas = 17.25 x 22.4
= 3.86 x 10² L
The answer is C.
Answer:
B
Explanation:
because G is recessive while g is dominant
Answer:
Weather forecasts are made by collecting as much data as possible about the current state of the atmosphere (particularly the temperature, humidity and wind) and using understanding of atmospheric processes (through meteorology) to determine how the atmosphere evolves in the future.
