Neutralization, the chemical reaction combining an acid with a base to produce a neutral solution produce produces a salt and

An acid and a base combined produce a salt and water.

The correct answer is water.

Explanation:

The neutralization reaction occurs when acid and base solutions react, producing water and a neutral ionic compound called salt. The word "salt" describes any ionic compound whose cation comes from a base (e.g. Na+ of NaOH) and whose anion comes from an acid (e.g. Cl- of HCl), while the rest of the elements react by forming water (H20).

Have a nice day!

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
