Answer:
D. So electrons can flow from one electrode to another
Explanation:
An electrochemical cell is any cell in which electricity is produced by reason of a chemical change.
An electrochemical cell consists of two electrodes, these two electrodes are connected using a wire.
Usually, electrons flow from one electrode to another via this wire thereby enabling the electrochemical processes of oxidation and reduction in the cell to proceed effectively.
Answer: second answer
Explanation:
The thing is that every new nuclear cycle a new element forms and reduces an electron. I may be wrong but this is the most logical and scientifically correct answer
The tool or instrument which is used to measure an object’s mass is electronic balance
Mass is a fundamental quantity
<h3>What is fundamental quantities?</h3>
Fundamental quantities can be defined as those physical quantities which forms the basic unit of measurement. They are the quantities upon which other quantities and units are derived from.
Mass is measured in kilograms (kg)
Other examples of fundamental quantities apart from mass are as follows:
- Length
- Time
- Amount of substances
- Luminous intensity
- Temperature
- Magnetic flux
So therefore, the tool or instrument which is used to measure an object’s mass is electronic balance
