To convert from liters/second to cubic gallons/minute, multiply the number of liters/second by 15.850 0 0.0353 00.2642 0 60

ivanzaharov [21]

Answer: 15.850

Explanation:

The conversion used from liters to gallons is:

1 L = 0.264172 gallon

The conversion used from sec to min is:

60 sec = 1 min

1 sec = $\frac{1}{60}\times 1=0.017min$

We are asked: liters/sec = gallons/min

$liters/sec=\frac{0.264172}{0.017}=15.850gallons/min$

Therefore, to convert from liters/second to gallons/minute, multiply the number of liters/second by 15.850.

2C6H10 + 17O2 = 12CO2 + 10H2O

Ad libitum [116K]

Answer:

n O2 = 2.125 mol

Explanation:

balanced reaction:

2C6H10 + 17O2 → 12CO2 + 10H2O

∴ n CO2 = 1.5 mol

⇒ n O2 = (1.5 mol CO2)*(17 mol O2/12 mol CO2)

⇒ n O2 = 2.125 mol
