How many hydrogen atoms are in 5.70 mol of ammonium sulfide?

Chemistry
1 answer:
QveST [7]3 years ago
3 0
<span>There are 2.74603 * 10^25 hydrogen atoms. Ammonium sulfide is represented by (NH4)2S. This means that there are 8 hydrogen atoms total. There are also 8 mol of H in ammonium sulfide. We also need to use avogadro’s number of 6.022 * 10^23. Hydrogen Atoms = 5.7mol * (8mol / 1mol) * 6.022 * 10^23 per mol Hydrogen atoms = 2.74603 * 10^25 hydrogen atoms.</span>

1st Define Covalent bond and it's type
irakobra [83]

Answer:

  1. COVELENT BOND:-The chemical bond formed by the sharing of an electron pair between two atoms so that both the atoms get their octet complete is called covalent bond
  • SINGLE COVELENT BOND:-it is formed by sharing of one pair of electron between two atoms
  • DOUBLE COVELENT BOND:-it is formed by sharing of two pair of electron between two atoms
  • TRIPLE COVELENT BOND:- it us formed by sharing of three pair of electron beyween two atoms

2)Electron dot structures of carbon dioxide:-Oxygen atom contains 6 valence electrons which form 2 lone pairs. Since it is bonded to only one carbon atom, it must form a double bond. Carbon atom contains four valence electrons, resulting in zero lone pairs. Therefore, it is doubly bonded to each oxygen atom.

3))Sulfur has an atomic number is 16 with the

symbol as 'S'

  • The electronic configuration of sulfur is said to be 2,8,6
  • The valence electrons present in sulfur is 6.
  • Sulfur forms an octet structure by connecting 8 sulfur atoms with each other by the formation of single covalent bonds.
  • The sulfur molecule's chemical formula is S8.
  • Sulfur is usually used in the manufacture of sulphuric acid.

For the reaction N2(g) + 3H2(g) ↔ 2NH3(g), the equilibrium constant, K, = 9.83 x 10-2 at a certain temperature and pressure.
pshichka [43]

The reaction is not at equilibrium and it is in the forward direction.

a.

Given,

[N₂] = 0.910 mol / L

[H₂] = 0.3 mol / L

[NH₃] = 0.0081 mol / L

K = 9.83 x 10⁻²

The balanced chemical equation for the given reaction is,

N₂(g) + 3H₂(g) ⇄ 2NH₃(g)

The formula of equilibrium constant is given by,

K = [NH₃]² / [N₂] [H₂]²

9.83 x 10⁻² = [(0.0081)² ]/ [0.910 × (0.3)²]

⇒9.83 x 10⁻² = (0.00006561) / (0.0819)

⇒9.83 x 10⁻² = 0.0008010989

⇒0.00983 = 0.0008010989

LHS ≠ RHS

Hence, the reaction is not at equilibrium.

b.

The reaction is in forward direction.

What is the molarity of 20.0 grams of NaOH dissolved in 1.50 L of solution?
Mariulka [41]
Molarity = moles/litre
mol/L=g/(g/mol) (which is g times mols per g)

will give you mols then divide that by L to get mol/L

so
M=g x mol/g x L
M=(20 x 1 x 1.50)/39.997

A photon has an energy of 2.78 x 1032 J. What is its wavelength?
8090 [49]

Answer:

7.14 × 10^(-58) m

Explanation:

We are given;

Energy; E = 2.78 x 10^(32) J

Formula to find this energy is;

E = hc/λ

Where;

E is energy

h is Planck's constant with a constant value of 6.62 × 10^(-34) J/s

c is speed of light with a constant value of 3 × 10^(8) m/s

λ is wavelength

Making λ the subject, we have;

λ = hc/E

λ = (6.62 × 10^(-34) × 3 × 10^(8))/(2.78 x 10^(32))

λ = 7.14 × 10^(-58) m
