ASAP!! Which one of the following substances can be produced during an acid-base neutralization reaction? A. Al(OH)3
B. HCl
C. H2O2
D. MgBr2

43.452

step-by-step explanation:

284 times .153 = 43.452

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.  

i think its 5049.

i hope this !

a corroding iron, if that's one of your choices
