Answer:
2H+ + SO4^2- +2Na+ + 2OH- ------------> 2Na+ + SO4^2- + 2H2O
Explanation:
In writing ionic reaction equations, we omit spectator ions, that is, ions that do not participate actively. Both the reactants and products are broken up into their constituent ions and a balanced equation involving ions only is written. Ionic equation balance usually require good knowledge of the reaction and nature of the reactants The dissolved compounds only are written as ions.
Silicon is a popular semi-conductor. The process of doping either creates an excess or lack of electrons. In the case of silicon, the dopant is arsenic which has greater valence electron than silicon. Arsenic then donates an electron resulting to an excess of electrons. A new type or better type of semi-conductor is created. Silicon conduct greater electricity.
The best answer is the last option.
The second one is more concentrated as they both times with the same thing but the second one (1.5) is bigger
