Answer:
C₁₂H₂₂O₁₁ and CH₃OH
Explanation:
Sucrose and methyl alcohol are nonelectrolytes. They do not ionize or conduct a current in aqueous solution.
HC₂H₃O₂ is a weak electrolyte. It produces only a few ions and is a poor conductor of electricity in aqueous solution.
HC₂H₃O₂ + H₂O ⇌ H₃O⁺ + C₂H₃O₂⁻
H₂SO₄ is a strong electrolyte. Its first ionization is complete, so it is a good conductor of electricity in aqueous solution.
H₂SO₄ + H₂O ⟶ H₃O⁺ + HSO₄⁻
Answer:
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
slow
fast
To determine the net chemical equation, we will simply add the above two equations, we get:
Order with respect to is 1 and Order with respect to
is 2.
Thus the rate law will be:
Answer:
Mass percentage of gold : 33.35%
Mass percentage of silver: 62.80%
Mass percentage of copper : 3.85%
Explanation:
Where : N = Number of atoms
n = moles
= Avogadro number
Let the total atoms present in the alloy be 100.
Atom percentage of silver = 44.9%
Atoms of of silver = 44.9% of 100 atoms = 44.9
Atomic weight of silver = 107.87 g/mol
Mass of 44.9 silver atoms = 107.87 g/mol × 44.9 = 4,843.363 g/mol
Atom percentage of gold= 46.3%
Atoms of of gold = 46.3% of 100 atoms = 46.3
Atomic weight of gold = 196.97 g/mol
Mass of 44.9 gold atoms = 196.97 g/mol × 46.3 = 9,119.711 g/mol
Atom percentage of copper = 8.8 %
Atoms of of copper = 8.8% of 100 atoms = 8.8
Atomic weight of copper = 63.55 g/mol
Mass of 44.9 copper atoms = 63.55 g/mol × 8.8 = 559.24 g/mol
Total mass of an alloy :4,843.363 g/mol + 9,119.711 g/mol + 559.24 g/mol
Mass percentage of gold :
Mass percentage of silver:
Mass percentage of copper :
