Answer is: seventy eight (78) atoms in this reaction.
In this balanced chemical reaction there are twelve carbon atoms (from two molecules of C₆H₁₄), twenty eight atoms of hydrogen (from two molecules of C₆H₁₄) and thirty eight atoms of oxygen (from nineteen molecules of oxygen):
12C + 28H + 38O = 78 atoms total.
Answer:
2
Explanation:
C⁴H¹⁰ + 2O² —> 4CH²O + H²
Times it bye for then ur answer will be 80
Question:
<span>A sample of nitrogen gas had a volume of 500mL, a pressure in its closed container of 740 torr and a temperature of 25°c. what was the volume of gas when the temperature was changed to 50°c and the new pressure was 760 torr?
Answer:
Data Given:
V</span>₁ = 500 mL
P₁ = 740 torr
T₁ = 25 °C + 273 = 298 K
V₂ = ?
P₂ = 760 torr
T₂ = 50 °C + 273 = 323 K
Solution:
Let suppose the gas is acting Ideally, then According to Ideal Gas Equation,
P₁ V₁ / T₁ = P₂ V₂ / T₂
Solving for V₂,
V₂ = (P₁ V₁ T₂) ÷ (T₁ P₂)
Putting Values,
V₂ = (740 torr × 500 mL × 323 K) ÷ (298 K × 760 torr)
V₂ = 527.68 mL
