J. J. Thomson discovered electron by performing an experiment using cathode ray tubes. High voltage across is applied across two electrodes at that causes a beam of particles to flow from the the negatively-charged electrode that is cathode to the positively-charged electrode that is anode. Properties of the particles, are tested using two oppositely-charged electric plates around the cathode ray. The cathode ray was deflected away from the negatively-charged electric plate and towards the positively-charged plate. This indicated that the cathode ray was composed of negatively-charged particles. And these negatively charged particles are called electrons.

Let us study about this reaction </h2>
Explanation:
This given reaction is a chemical reaction that is : Double decomposition reaction .
In this reaction , there is a reaction between two compounds in which they mutually interchange their ions .
That is :
AB +CD ---> AC +BD
Similarly in this we have :
Na3PO4+KOH—->NaOH + K3PO4
The double decomposition reaction is either :
Precipitation reaction : resulst in the formation of ppt .
Neutralization reaction : results in the formation of neutral substance
Carbon monoxide is a carbon atom bonded with an oxygen atom. Carbon dioxide is a carbon atom bonded with <em>two</em> oxygen atoms. That's it really, they have different properties but that is significantly more detailed and all a result of their molecular formula.
The answer to this question is 850 kilometers
<u>Answer:</u> The indicators written will identify a new substance is formed in a chemical equation.
<u>Explanation:</u>
A chemical equation is defined as the equation in which reactants and products are present and are separated by a right arrow.
Indicators of a chemical reaction are:
- Formation of a precipitate
- Evolution of gas
- Formation of bubbles
- Color change
- Specific odor
- Change in temperature
Hence, the indicators written will identify a new substance is formed in a chemical equation.
