if a displacement reaction is performed by adding 9.5g of zinc and 9.5g of HCl how much zinc will be produced?

Explanation:

Zinc metal reacts with hydrochloric acid to produce zinc chloride and hydrogen gas. a. ... A 3.50-g sample of zinc metal is allowed to react with 2.50 g of hydrochloric acid. ... If 4.20 g of ZnCl, and 500-9°Ñ, are produced what is the percent yield of each product? ... How many grams of Fe3(PO4)2 precipitate can be form. 4

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.
