Pressure caused by high temperatures are balanced by gravity
<h3>
Answer:</h3>
An electric current is used to decompose a substance.
<h3>
Explanation:</h3>
Concept tested: Electrolysis
We can answer the question by asking ourselves important questions
First; What is electrolysis?
- Electrolysis refers to the process through which molten or aqueous compound known as electrolytes are decomposed by passing electric current through them.
Second; What are electrolytes?
- Electrolytes are substances in either molten or aqueous form and are good conductors of electric current.
- Electrolytes are good conductors of electric current due to the presence of mobile ions.
Third: What happens during electrolysis?
- Electrolytes are therefore decomposed by passing electric current through them resulting to formation of new elements or molecules.
- For example, when molten sodium chloride is decomposed by passing electric current through it, sodium metal is released at the cathode while chlorine is released at the anode.
The muscular and skeletal system because we use our brain to move our body it sends a signal to move that muscle that we want to use
Answer:
Approximately
.
Explanation:
Make use of the molar mass data (
) to calculate the number of moles of molecules in that
of
:
.
Make sure that the equation for this reaction is balanced.
Coefficient of
in this equation:
.
Coefficient of
in this equation:
.
In other words, for every two moles of
that this reaction consumes, two moles of
would be produced.
Equivalently, for every mole of
that this reaction consumes, one mole of
would be produced.
Hence the ratio:
.
Apply this ratio to find the number of moles of
that this reaction would have produced:
.
