%yield = 54.6%
<h3>Further explanation</h3>
Percent yield is the compare of the amount of product obtained from a reaction with the amount you calculated
(theoretical)
General formula:
Percent yield = (Actual yield / theoretical yield )x 100%

Reaction
2ZnS+3O₂ ⇒ 2ZnO+2SO₂
MW ZnS = 97.474 g/mol

MW ZnO = 81.38 g/mol
- mol ZnO (from mol ZnS as limiting reactant, O₂ excess)


Theoretical production = 125.388

Answer:
0.5mol/L
Explanation:
First, let us calculate the number of mole NaOH = 23 + 16 + 1 = 40g/mol
Mass of NaOH from the question = 30g
Number of mole = Mass /Molar Mass
Number of mole = 30/40 = 0.75mol
Volume = 1.5L
Active mass = mole/Volume
Active mass = 0.75mol/1.5L
Active mass = 0.5mol/L
Gold alloys consist of most commonly Nickel!
Most commonly used in things like jewelry so it doesn't have such a heavy weight.
Answer : The reactant acid and conjugate base in this reaction is,
and
.
Explanation :
Conjugate acid : A species that is formed by receiving of a proton
by a base is known as conjugate acid.
Conjugate base : A species that is formed by donating of a proton by an acid is known as conjugate base.
The given chemical reaction is,

In this reaction,
(base) react with
(acid) to give
(conjugate acid) and
(conjugate base).
Therefore, the reactant acid and conjugate base in this reaction is,
and
.
