<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.
Answer:
Yes is incorrect
Explanation:
not all veins carry blood rich in CO2 , the pulmonary vein carries blood with O2 which means that not all veins carry blood rich in CO2

2. Calculate the concentration
Answer:
A computer's ability to perform so many calculations in a very short time affects how people communicate by stopping them from talking actually. We no longer talk verbally. We don't go out and socialize, we always talk from the phone or text. We have lost our inner touch with talking.

Answer:
Theoretical value is the value a scientist expects from an equation, assuming perfect or near-perfect conditions. Experimental value, on the other hand, is what is actually measured from an experiment. Rarely (in fact never) are these numbers the same.
Take the area of a sheet of paper. I know that the area of a rectangle can be found by multiplying the lengths of both sides together. I can assume an 8.5x11 sheet, so I calculate exactly 93.5 square inches. This is my theoretical value. When I actually do the measurements on my paper, it turns out my paper has been slightly cut on one end, or I’m measuring with a shoddy ruler. Therefore, I might measure only 92.8 square inches. This is my experimental value. See thats it’s close, but not exact.
Expanding on this concept, quantum mechanics is so widely accepted in the scientific community because many theoretical values calculated by mathmaticians concurred with experimental values to many, many decimal places. These would be constants such as Plank’s Constant, energy levels of harmonic potentials, and energy levels of the hydrogen atom.
