You have an atom represented by X (not real by the way). X has 2 valence electrons. You have another atom Y that has 5 valence e

BabaBlast [244]

The chemical formula : X₃Y₂

<h3>Further explanation </h3>

The noble gas element is a stable class of elements. The noble gas element is monatomic. Stability of noble gases is caused by an electron configuration that has a stable configuration of 8 (has 8 valence electrons) except He with a duplet configuration (has 2 valence electrons)

Other elements that do not yet have electron configurations such as noble gases will try to achieve their stability by forming bonds between elements.

This is generally called the octet rule

X has 2 valence electrons.to achieve stability, element X will release 2 electrons to form X²⁺

Y has 5 valence electrons, to achieve stability, the element Y will attract/ add electrons to form Y³⁻

The two compounds will form a compound with the charges crossed : X₃Y₂

Reading a Periodic Table
Using Stoichiometry

<h3>Explanation:</h3>

<u>Step 1: Define</u>

[RxN] 4HCl (g) + 6NO (g) → 5N₂ (g) + 6H₂O (g)

[Given] 404.87 g HCl

<u>Step 2: Identify Conversions</u>

[RxN] 4 mol HCl = 5 mol N₂

Molar Mass of H - 1.01 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of HCl - 1.01 + 35.45 = 36.46 g/mol

Molar Mass of N - 14.01 g/mol

Molar Mass of N₂ - 2(14.01) = 28.02 g/mol

<u>Step 3: Stoichiometry</u>

<u /> $404.87 \ g \ HCl(\frac{1 \ mol \ HCl}{36.46 \ g \ HCl} )(\frac{5 \ mol \ N_2}{4 \ mol \ HCl} )(\frac{28.02 \ g \ N_2}{1 \ mol \ N_2} )$ = 388.935 g N₂

<u>Step 4: Check</u>

<em>We are given 5 sig figs. Follow sig fig rules and round.</em>

388.935 g N₂ ≈ 388.94 g N₂

Question:

1. (NH)2CrO

a) Number of moles of H:

b) Number of moles of N:

Answer:

a) Number of moles of H: 2

b) Number of moles of N: 2

Explanation:

The $(NH)_2CrO$ is ammonium Chromate which is monoclinic and yellow Crystal that is formed due to the reaction of ammonium Hydroxide and ammonium di-chromate. It is used as catalyst, corrosion inhibitor as well as analytical inhibitors.
