%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
Air is a mixture of several gasses
Answer/Explanation:
Wave W is being diffracted, Wave X is being reflected, and waves Y and Z are being refracted.
Answer the correct option will be option B.
Explanation: this is how he showed the electron could orbit the nucleus without falling into it. This is so because he explained that the electron revolves around the nucleus in a fixed circular orbit with fixed energy and cannot occupy just any energy level which is defined as quantisation of energy.
option A is one of postulates given by Dalton in his Dalton's atomic theory which later proved to be wrong.
option C it is one of the postulates given by the in J.J Thomson in his model of an atom which was the first atomic model.
option D Schrodinger has used the wave nature to explain the position of electrons around the nucleus.
Answer:
The answer is
<h2>22 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of liquid = 44 g
volume = 2 mL
The density of the liquid is
We have the final answer as
<h3>22 g/mL</h3>
Hope this helps you
