In this chemical reaction how many grams of al 203 will be produced if 175 g of al react completely

330.56g

Explanation:

175________x

4Al+3O₂=2Al₂O₃

4×27____2×102

m(Al₂O₃)=x=

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.  

your answer is c) plasma
