Answer:

3.4 mol C3H8

Explanation:

Balance: C3H8 + 5O2 → 3CO2 + 4H2O

Use a molar ratio to determine the amount needed.

13.6 mol H2O * 1 mol C3H8/4 mol H2O = 3.4 mol C3H8

E85 fuel is a mixture of 85% ethanol and 15% gasoline by volume. What mass in kilograms of E85 (d = 0.758 g/mL) can be contained

NISA [10]

Convert gal to liters:

14.0 gal x 3.785 L / gal = 53.0 L

Multiply volume by density (the density would have the units of .758 g/mL or .758 kg / L)

53.0 L x .758 kg/L = <span> 40.2 kg</span>

Balance the following equations: (c) H2(g)+I2(s)⟶HI(s)H2(g)+I2(s)⟶HI(s)

kenny6666 [7]

Answer: $H_2(g)+I_2(g)\rightarrow 2HI(s)$

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

Thus in the reactants, there are 2 atoms of hydrogen and 2 atoms of iodine .Thus there has to be 2 atoms of hydrogen and 2 atoms of iodine in the product as well. Thus a coefficient of 2 is placed in front of HI.

The balanced chemical reaction is:

$H_2(g)+I_2(g)\rightarrow 2HI(s)$
