If 2.0 mol of Zn is mixed with 3.0 mol of HCl, which reactant will be limiting?

Chemistry
1 answer:
Soloha48 [4]2 years ago

The following Balanced Reaction will take place:

Zn + 2HCl → ZnCl₂ + H₂

In the question, we have 2 moles of Zinc and 3 moles of HCl for this reaction

<u>Amount of HCl required to completely react with 2 moles of Zn:</u>

Since we need 2 moles of HCl for every mole of Zn, we will need 2(2) = 4 moles of HCl for every 2 moles of Zn

<u>Identifying the Limiting Reagent:</u>

But we are only given 3 moles of HCl where we need 4 moles to completely react.

So, since HCl is in less amount, it is the Limiting Reagent

The vapor pressure of pure acetone (C3H6O) is 216 torr
svetoff [14.1K]

The mole fraction of acetone (C₃H₆O) is 0.333

<h3>Data obtained from the question </h3>
  • Mole of C₃H₆O = 0.1 mole
  • Mole of CHCl₃ = 0.2 mole
  • Mole fraction of C₃H₆O =?

<h3>How to determine the mole fraction </h3>

Mole fraction of a substance can be obtained by using the following formula:

Mole fraction = mole / total mole

With the above formula, we can obtain the mole fraction of C₃H₆O as follow:

  • Mole of C₃H₆O = 0.1 mole
  • Mole of CHCl₃ = 0.2 mole
  • Total mole = 0.1 + 0.2 = 0.3 mole
  • Mole fraction of C₃H₆O =?

Mole fraction = mole / total mole

Mole fraction of C₃H₆O = 0.1 / 0.3

Mole fraction of C₃H₆O = 0.333

Find the formula for the compound that contains 72.40% iron and 27.60% oxygen.
Vikki [24]
Oxygen = 16
Iron = 55.8
16 x 27.6% = 4.4 /4 = 1.1
55.8 x 72.4% = 40.4 /4 = 10.1
1 oxygen and 10 iron, so Fe10 O
