Show that these observations are in agreement with the law of conservation of mass, sodium carbonate + ethanoic acid —> sodium ethanoate + carbon dioxide + water.
yes they are in the law of conservation of mass by taking 2 molecules of ethanoic acid and 2 molecules of sodium ethanoate
Explanation:
the chemical formula of
sodium carbonate =Na2CO3
ethanoic acid is also known as acetic acid =CH3COOH
sodium ethanoate=CH3COONa
carbon dioxide =CO2
water =H2O
now taking the balanced equation
1 molecules of sodium carbonate + 2molecules of ethanoic acid gives 2 molecules of sodium ethanoate + one molecule of carbon dioxide +one molecule of water
by this balanced equation all the carbon atoms ,hydrogen atoms, sodium atoms, oxygen atoms are balanced
so the law of conservation of mass is verified
the law of conservation of mass is " mass is neither created nor destroyed in chemical reactions."
this law states that the total number of atoms in reaction is equal to the total number of atom in the products
here in the given chemical formula
the law of conservation of mass is satisfied by taking the required number of molecules in the reaction and product
