What is the overall charge of an atom. ​
Sveta_85 [38]

Overall, an atom is neutral charged. The Bohr model was for years accepted as the final authority because it agrees so well with experiment and observation. In this model an atom consists of a nucleus containing protons and neutrons. The neutrons are zero charge so we can forget them in looking for charges. For each proton (1 positive charge) there is always 1 electron (1 negative charge) in orbit around the nucleus. thus an atom has a equal number of electrons and protons and their net charge is zero.

We can do things to temporarily up set this natural balance (we call this electricity) but the atoms will eventually return to their naturally balanced state

First, let's count mole of 10 g Calcium Carbonate

mole = Mass / Molecular Mass

Calcium Carbonate = CaCO₃

Molecular Mass = Ar Ca + Ar C + (3 x Ar O)

Molecular Mass = 40 + 12 + (3 x 16)

Molecular Mass = 100

next

Mole of CaCO₃ = 10 gram / 100

Mole of CaCO₃ = 0,1 mol

then equal the reaction equation first

 CaCO₃ + 2 HCl  ==>  CaCl₂ +  CO₂  +  H₂O     (Equal)

To count the mass of carbon dioxide that produced we must know the mole of CO₂ first

we can count by coefficient comparison

mole CO₂ = \frac{coefficient \ of \ CO_2}{coefficient \ of \ CaCO_3}  x mole CaCO₃

mole  CO₂ =  (1/1)  x 0,1 mole

mole  CO₂ = 0,1 mole

so

Mass of  CO₂ = mole  CO₂ x  Molecular Mass of  CO₂

Mass of  CO₂ = 0,1 mole x (12 + (2 x 16))

Mass of  CO₂ = 0,1 mole x 44

Mass of  CO₂ = 4,4 g

so, mass of carbon dioxide that's produced by 10 g of calcium carbonate on reaction with chloride acid is 4,4 g.
