Use the unbalanced chemical equation to answer the question.
2NaHCO3 → Na2CO3 + CO2
Which of the following can be added to the products to balance the equation?
The unbalanced equation is:
2NaHCO3 → Na2CO3 + CO2
To balance the equation, we need to have an equal number of atoms on both sides of the equation. In this case, we have 2 sodium (Na) atoms on the left side but only 1 sodium atom on the right side.
To balance the equation, we need to add another sodium atom to the right side. Therefore, the compound that can be added to the products to balance the equation is NaHCO3.
To balance the chemical equation 2NaHCO3 → Na2CO3 + CO2, we need to add the correct coefficients to each compound or molecule in the equation.
In this case, we see that there are 2 sodium atoms on the left side (2Na) and only 1 sodium atom on the right side (Na2CO3). Therefore, we need to add a coefficient of 2 in front of Na2CO3 to balance the sodium atoms.
The balanced equation becomes:
2NaHCO3 → 2Na2CO3 + CO2
To balance a chemical equation, you need to have the same number of each type of atom on both sides of the equation. In this case, we have 2 sodium (Na) atoms on the left side of the equation, but only 1 sodium atom on the right side.
To balance the equation, we need to add a coefficient in front of Na2CO3 to get 2 sodium atoms on the right side. Since there is already one sodium atom in Na2CO3, we need to multiply Na2CO3 by 2 to obtain 2 sodium atoms. The balanced equation would then be:
2NaHCO3 → 2Na2CO3 + CO2
Therefore, the correct answer would be "2Na2CO3". By adding 2Na2CO3 to the products, we ensure that both the left and right sides of the equation have an equal number of sodium atoms.
