What volume of hydrogen iodide is produced when 118 liters of hydrogen gas react according to the following reaction? (All gases
Nadya [2.5K]

Answer:

V_{HI}=236LHI

Explanation:

Hello,

In this case, for the given balanced chemical reaction:

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

Thus, since hydrogen and hydrogen iodide are in a 1:2 mole ratio, we can easily compute the yielded volume as shown below:

V_{HI}=118LH_2*\frac{2molHI}{1molH_2} \\\\V_{HI}=236LHI

Thus, is possible, due to the Avogadro's law which allows to relate moles and volume by a directly proportional relationship.

Regards.

What mass of NaOH is in 3.0e+02 mL of a 5.0 M NaOH solution?
Snezhnost [94]
Answer is: mass of sodium hydroxide is 60 grams.
V(NaOH) = 300 mL · 1 L/1000mL = 0,3 L.
c(NaOH) = 5 M = 5 mol/L.
n(NaOH) = c(NaOH) · V(NaOH).
n(NaOH) = 5 mol/L · 0,3 L.
n(NaOH) = 1,5 mol.
m(NaOH) = n(NaOH) · M(NaOH).
m(NaOH) = 1,5 mol · 40 g/mol.
m(NaOH) = 60 g.
