Answer:
The correct option is: (C) It included negatively charged particles.
Explanation:
Sir Joseph John Thomson proposed an atomic model, known as the plum pudding model in 1904.
In this model, he<u> compared an atom to a plum pudding</u> and suggested that the <u>negatively charged electrons are the plums that are embedded in a uniform positively charged spherical pudding.</u>
Therefore, according to the plum pudding model, <u>an atom has no net electric charge</u> and <u>contains negatively charged electrons.</u>
Answer: true
Explanation: An atom does of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. Protons and neutrons have nearly equal masses, but in a way they DO differ in charge.
The equation of the proton transfer is:
- NaC₆H₅CO₂ + H₂O ⇄ C₆H₅CO₂H + NaOH
<h3>What are acids?</h3>
Acids according to the Bronsted-Lowry definition, are substances that donates one or more hydrogen ions to another substance in a chemical reaction.
The substances that receive the proton are called bases.
Hydrogen ions are considered as protons. The hydrogen ions produced by acids results in a pH of less than 7 for acid solutions.
Considering the given substances, the equation of the proton transfer is given below:
NaC₆H₅CO₂ + H₂O ⇄ C₆H₅CO₂H + NaOH
The compound NaC₆H₅CO₂, sodium benzoate, is a base and accepts protons from H₂O which serves as the acid.
H₂O serve as the acid by transferring protons to NaC₆H₅CO₂ and then, NaOH is formed.

There are no numbers provided so I will try to explain the equation. If you want to find the percent error you would do theoretical (the number it’s supposed to be) minus experimental (the number you got in the experiment) over the theoretical value (same as the first one.) You must multiply this by 100 in order to show the actual percentage rather than very low decimals. You want the percent error to be as low as possible because the lower it is the less mistakes happened. Mistakes can include too much/less of solvent, solution, or the glassware wasn’t clean enough, and much much more.
I hope this helps!
