Hi,
The answer is +2, since there are 10 positive charges (protons) and 8 negative charges (electrons), so 10(+1) + 8(-1)= +10 -8= +2.
If my answer was not clear enough or you’d like further explanation please let me know.
Hope this helps!
It’s organized by the atomic number which is the protons so the answer is A although they can be organized through groups and periods if valance electrons are included
Answer:
The electron is subatomic particle that revolve around outside the nucleus and has negligible mass. It has a negative charge.
relative charge = -1
Relative mass = 1.1836
It was discovered by j. j. Thomson in 1897 during the study of cathode ray properties.
He constructed the glass tube and create vacuum in it. He applied electric current between electrodes. He noticed that a ray of particles coming from cathode to wards positively charged anode. This ray was cathode ray.
Properties of cathode ray:
The ray is travel in straight line.
The cathode ray is independent of composition of cathode.
When electric field is applied cathode ray is deflected towards the positively charged plate.
Hence it was consist of negatively charged particles.
While neutron and proton are present inside the nucleus. Proton has positive charge while neutron is electrically neutral. Proton is discovered by Rutherford while neutron is discovered by James Chadwick in 1932.
Relative mass of proton= 1
Relative mass of neutron = 1
Relative mass of proton = +1
Relative charge of neutron = 0
The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons. The umber of protons and electrons are always equal to make the atom electrically neutral.
Explanation:
The equation of the neutralization reaction is:
HOC(CO₂H)(CH₂CO₂H)₂ + Na₂CO₃ ----> HOC(CO₂Na)(CH₂CO₂Na)₂ + H₂O
<h3>What is the acid in lemon juice?</h3>
The main acid in lemon juice is citric acid.
Citric acid is a tricarboxylic acid and will react with baking soda to form a salt and water.
The equation of the neutralization reaction is shown below:
HOC(CO₂H)(CH₂CO₂H)₂ + Na₂CO₃ ----> HOC(CO₂Na)(CH₂CO₂Na)₂ + H₂O
In conclusion, the neutralization of citric acid in lemon juice produces a salt and water.
