constract the neutralisation rxn of calos antacid and stomach acid,and balance it?
To construct the neutralization reaction between Tums antacid (calcium carbonate) and stomach acid (hydrochloric acid), we need to first understand the chemical formulas of the two compounds.
Tums antacid contains calcium carbonate (CaCO3), and stomach acid consists mainly of hydrochloric acid (HCl).
The neutralization reaction can be represented as follows:
CaCO3 + 2HCl -> CaCl2 + CO2 + H2O
To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's balance it step by step:
1. Start with the calcium (Ca) atoms:
There is one Ca on the left side and one Ca on the right side, so it is already balanced.
2. Move on to the hydrogen (H) atoms:
There are two Hs on the left side from HCl and two Hs on the right side from water (H2O). Hence, at this point, Hs are balanced.
3. Balance the chlorine (Cl) atoms:
There are two Cls on the right side from CaCl2. To balance, we need to add a coefficient of 2 in front of HCl on the left side:
CaCO3 + 2HCl -> CaCl2 + CO2 + H2O
4. Finally, balance the carbon (C) and oxygen (O) atoms:
There is one C on the left side from CaCO3, and one C on the right side from CO2.
Also, there are three O atoms on the left side (from CO3 in CaCO3) and three O atoms on the right side (two from CO2 and one from H2O).
The final balanced equation is:
CaCO3 + 2HCl -> CaCl2 + CO2 + H2O
This equation represents the neutralization reaction between Tums antacid (calcium carbonate) and stomach acid (hydrochloric acid).
