What is the correct formula that would result from the combination
of the two ionic species?
Cs1+ and Ci1-

CsCl

Explanation:

The ionic species are:

            Cs⁺   and Cl⁻

The two ions will combine to form an ionic compound which results from the electrostatic attraction between oppositely charged ions.

Elements or ions exchange directly their combining powers or their simplest whole number ratio during the formation of chemical formulae of compounds

                                Cs⁺   and Cl⁻

Combining power      1             1  

Exchange of

valencies                     1             1

      Compound CsCl

lol for the pointsss

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
