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.
The two correct statements are:
1. The concentration of one or more of the products is small
2. The reaction will proceed to the right and favor the formation of products.
LeChatelier's Principle states that when a stress is imposed on a system at equilibrium, the equilibrium will shift to counteract the change. A reduction in the number of products cause the system to respond by making more product, which leads to K>1 and products being more favorable.

Here you go I hope it helped you! :) good luck!
english:
In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time.
spanish:
En física y química, la ley de conservación de la energía establece que la energía total de un sistema aislado permanece constante; se dice que se conserva con el tiempo.
