These are the formulas of each compound mentioned:
1) Hydrogen chloride: HCl
2) Sodium hydrogen carbonate: NaHCO3 , this is also known as sodium bicarbonate. The number 3 to the right of O is a subscript.
3) Sodium chloride: NaCl
4) Carbon dioxide: CO2. This is also known as carbon anhydride. The number 2 to the right of O is a subscript.
5) Water: H2O. The number 2 to the right of H is a subscript.
The the chemical equation is:
HCl + NaHCO3 → NaCl + CO2 + H2O
Check the balance
element left side right side
H 1+1 = 2 2
Cl 1 1
Na 1 1
C 1 1
O 3 2+1 = 3
Then, given that the number of each element on the left side is equal to the number of elements in the right side, the equation is balanced.
Nb, the transition metal(d) subshell will always be n-1, meaning the 3d subshell will be in row(period) 4. So if it’s 4d then it is row(period) 5, and if it has 3 valence electrons then the element is located in column V, or the third column in the transition metal section.
