Answer : The correct option is, Electron.

Explanation :

There are three subatomic particles of an atom which are electrons, protons and neutrons. The protons are positively charged, the electrons are negatively charged and neutrons are neutral (no charge).

A neutral atom is an atom that has same number of electrons and protons.  When a neutral atom gain an electron, it becomes a negatively charged ion.  When a neutral atom lose an electron, it becomes a positively charged ion. That means the atom change when the electron is lost or gained.

Hence, if the atom undergoes a change and becomes a positive ion, in this process the lost subatomic particle is electron.

Electrons are lost because they have a negative charge. neutrons are neutral meaning no charge and protons have a positive charge

lilavasa [31]
According to Dalton's Atomic Theory, the <em>Law of Definite Proportion is applied when a compound is always made up by a fixed fraction of its individual elements.</em> This is manifested by the balancing of the reaction.

The reaction for this problem is:

H₂ + Cl₂ → 2 HCl

1 mol of H₂ is needed for every 1 mole of Cl₂. Assuming these are ideal gases, the moles is equal to the volume. So, if equal volumes of the reactants are available, they will produce twice the given volumes of HCl.

How many grams of MgCl2 (molar mass = 95.20 g/mol) will be formed from 25.6 mL of a 0.100 M HCL solution reacting with excess ma
lorasvet [3.4K]
The balanced equation for the above reaction is as follows;
Mg + 2HCl ---> MgCl₂ + H₂
stoichiometry of HCl to MgCl₂ is 2:1
we have been told that Mg is in excess therefore HCl is the limiting reactant 
number of HCl moles reacted - 0.100 mol/L x 0.0256 L = 0.00256 mol
according to molar ratio, number of MgCl₂ moles formed - 0.00256/2 
Therefore number of MgCl₂ moles formed - 0.00128 mol
mass of MgCl formed - 0.00128 mol x 95.20 g/mol = 0.122 g
