How many moles of copper Il sulfide can be produced from 2.8 moles of sulfur? Cu + S --> CuS​

Chemistry
1 answer:
Kamila [148]3 years ago
5 0

Answer: 2.8 moles of copper (Il) sulfide (CuS) will be produced from 2.8 moles of sulphur.

Explanation:

The balanced chemical reaction is:

Cu+S\rightarrow CuS  

According to stoichiometry :

1 mole of S produce =  1 mole of copper (Il) sulfide (CuS)

Thus 2.8 moles of S will produce=\frac{1}{1}\times 2.8=2.8moles of copper (Il) sulfide (CuS)

Thus 2.8 moles of copper (Il) sulfide (CuS) will be produced from 2.8 moles of sulphur.

Given the following equation: 2 K + Cl2 ---> 2 KCl
Ksivusya [100]

Answer:

2 moles of KCl will be produced

Explanation:

Given parameters:

Number of moles of K = 2 moles

Unknown:

Number of moles of KCl produced  = ?

Solution:

To solve this problem;

Obtain a balanced chemical equation:

           2K +  Cl₂   →   2KCl ;

Since K is the limiting reactant, its amount will determine the extent of this reaction.

   From the balanced equation;

           2 moles of K will produce 2 moles of KCl

        Given that 2 moles of K reacted, 2 moles of KCl will be produced

which statement is true about the part of the electromagnetic spectrum that is visible to the human eye?
IgorLugansk [536]
Hello @Lucysrv18,

How are you doing? In this case, we know that Electromagnetic waves that are visible to the human eye is neither made up of two electromagnetic waves nor three. Therefore B and C is incorrect.

These electromagnetic waves are divided and they are our final two options. For sure, i can say that the wavelengths in a visible electromagnetic wave are not divided into nine, but instead it is divided into 7. 

The answer to your question is A. 

Thank you,
Darian D.
