What is the empirical formula of C3H6N2
Evgen [1.6K]

Answer:

The empirical formula of the compound C₃H₆N₂ is C₃H₆N₂

Explanation:

The empirical formula of a compound is the formula of the compound given in the (smallest) whole number ratio of the elements of the compound

The empirical formula of S₂O₂ is SO

The empirical formula of C₃H₆O₃ is CH₂O

The given compound's molecular formula is C₃H₆N₂

The smallest whole number ratio of of the elements of the compound is 3:6:2, therefore, the empirical formula of the compound C₃H₆N₂ is C₃H₆N₂.

How many total moles of ions are released when the following sample dissolves completely in water? 6.188 x 10 21 formula units o
elixir [45]

Answer:

e. 3.08 x 10⁻² mol of ions.

Explanation:

  • Every 1.0 mole of any compound contains Avogadro's number of molecules (6.022 x 10²³).

  • We can get the no. of moles of NiCl₂ using cross multiplication:

1.0 mol NiCl₂ contains → 6.022 x 10²³ molecules.

??? mol NiCl₂ contains → 6.188 x 10²¹ molecules.

∴ The no. of moles of NiCl₂ = (1.0 mol)(6.188 x 10²¹ molecules)/(6.022 x 10²³ molecules) = 1.028 x 10⁻² mol.

  • NiCl₂ is ionized according to the equation:

NiCl₂ → Ni²⁺ + 2Cl⁻.

Which means that every 1.0 mol of NiCl₂ is ionized to produce 3.0 moles (1.0 mol of Ni²⁺ and 2 moles of Cl⁻).

<em>∴ The total moles of ions are released</em> = 3 x 1.028 x 10⁻² mol = <em>3.083 x 10⁻² mol of ions.</em>

sweet-ann [11.9K]

Answer:

  • All matter is composed of atoms.
  • Atoms are not destructible.
  • Compounds formation occur by the combination of one or different types of atoms
  • In the chemical reactions, atoms are rearranged.
  • The atom of the same elements are similar in size and properties and the Atoms of the different elements are different in size and properties.

Explanation:

  • <u>John Dalton has developed the Dalton atomic theory.</u>
  • Dalton atomic theory was the first to explain that all matters composed of atoms and its properties, the atom as the smallest particle which cannot be destroyed and damaged.
  • This theory was based on the <u>law of conservation of mass and law of constant composition.</u>
  • His theory was accepted by many scientists.
