Which of the following is not a correct acid-base neutralization reaction? hi + koh --> ki + h20 ca(oh)2 + hcl --> cacl + h2o ch3cooh _ nh4oh --> nh4ch3coo + h2o hbr _ csoh --> csbr + h2o

Ca(OH)2  + HCl →  CaCl  + H2O   is  not a correct acid- base  neutralization reaction

    Explanation

 Acid and base react to form   salt and water.

The  reaction of Ca(OH)2 + HCl →  CaCl2 +H2O  is not  correct  because  

Therefore the correct acid -base  neutralization  reaction  is as below

Ca(OH)2  + 2HCl→  CaCl2   + 2H2O

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
