Answer: A. the rotational period of the earth is the same as that of the moon
Charles law gives the relationship between temperature of gas and volume of gas.
It states that for a fixed amount of gas, temperature is directly proportional to volume of gas.
V / T = k
where V- volume , T - temperature and k - constant

parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation.
T1 = 250 °C + 273 = 523 K
T2 = 150 °C + 273 = 423 K
Substituting the values in the equation,

V = 251 mL
the new volume is 251 mL
It’s C. 4.68 N

Answer:
The answer to your question is 1544 g of CO₂
Explanation:
Data
mass of octane = 500 g
mass of CO₂ = ?
Balanced chemical reaction
2C₈H₁₈ + 25O₂ ⇒ 16CO₂ + 18H₂O
Process
1.- Calculate the molar mass of octane and of carbon dioxide
C₈H₁₈ = 2[(12 x 8) + (1 x 18)] = 2[(96 + 18] = 2[114] = 228 g
CO₂ = 16[(12 x 1) + (16 x 2)] = 16[12 + 32] = 16[44] = 704 g
2.- Calculate the mass of carbon dioxide produced
228 g of C₈H₁₈ ---------------- 704 g of CO₂
500 g of C₈H₁₈ --------------- x CO₂
x = (500 x 704) / 228
x = 352000/228
x = 1544 g of CO₂
