What is the simplest formula of a compound if a sample of the compound contains 0.221 mol X, 0.442 mol Y, and 0.884 mol Z? chemP
Gnoma [55]

Answer:

XY₂Z₄

2.35 mol Z

Explanation:

A sample of the compound contains 0.221 mol X, 0.442 mol Y, and 0.884 mol Z. We can find the simplest formula (empirical formula) by <em>dividing all the numbers of moles by the smallest one</em>.

X: 0.221/0.221 = 1

Y: 0.442/0.221 = 2

Z: 0.884/0.221 = 4

The simplest formula is XY₂Z₄.

The molar ratio of X to Z is 1:4. The moles of Z in a sample that contained 0.588 moles of X is:

0.588 mol X × (4 mol Z/1 mol X) = 2.35 mol Z

<h2>The compound formed is NaCl and CaCl_{2}</h2>

Explanation:

     PART 1:

  • Atomic number of sodium is 11.
  • Sodium(Na, Z = 11, Group 1A) will lose 1 electron to become Na^{1+} which is isoelectronic to Neon (Ne ,Z = 10).
  • The symbol for the sodium ion is Na^{+}.
  • Chlorine atom (Cl, Z = 17, Group 7A or 17) gains 1 elecron to be  isoelectronic to neon.
  • The symbol for the compound formed is NaCl.
  • PART 2:
  • Atomic number of calcium is 20
  • Calcium(Ca, Z = 20 ,Group 2A) will lose two electrons to become Ca^{2+}which is isoelectronic to argon.
  • The symbol for the ion is Ca^{2+}.
  • Two chlorine atoms (Cl, Z = 17, Group 7A or 17) each gains one electron to be isoelectronic to argon(Z = 18)
  • The symbol for the compound formed is CaCl_{2}.
