Based on Arrhenius theory, explain why CaCI2(aq) can be considered a neutral solution rather than an acidic solution or a basic solution?

Another question is in an experiment ammonia has, NH3(aq) reacted with the water to form the aqueous ammonia ions, NH4+(aq). When red litmus paper was placed in contact with the aqueous solution the paper turned blue. This indicated a basic solution.

a. Identify the acid and the base in the reaction between dissolved ammonia gas, Nh3(aq) and water. Explain your answer

B. Identify the conjugate acid and the conjugate base of the reaction. Explain your answer

C. Write the complete chemical equation for the reaction between NH3(aq) and H2O(I)

Another question is: The oxides is carbon, sultry and nitrogen can be harmful when released into the atmosphere. Why are these oxides so harmful. Give one reason that applies to all these oxides?

a. a clone will be physically identical to the original, but won’t be genetically identical

have a good day!

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
