how do I write a balanced equation showing aqueous hydrogen carbonate, to give liquid water and carbon dioxide gas
H2O(l) + CO2(g) ==>H2CO3(aq) to show the formation of dihydrogen carbonate (carbonic acid).
To show the decomposition of H2CO3.
H2CO3(aq) ==> H2O(l) + CO2(g)
Aq- g +l
To write a balanced equation showing the formation of liquid water and carbon dioxide gas from aqueous hydrogen carbonate, you can follow these steps:
Step 1: Write the reactants and products:
Aqueous hydrogen carbonate + Liquid water → Carbon dioxide gas
Step 2: Write the chemical formula for each compound:
Aqueous hydrogen carbonate is HCO3^- (hydrogen carbonate ion) in water solution.
Liquid water is H2O.
Carbon dioxide gas is CO2.
Step 3: Write the unbalanced equation:
HCO3^- + H2O → CO2
Step 4: Balance the equation by adjusting the coefficients:
2HCO3^- + H2O → CO2 + H2O
The balanced equation for the formation of liquid water and carbon dioxide gas from aqueous hydrogen carbonate is:
2HCO3^- + H2O → CO2 + H2O
To balance the equation showing the formation of aqueous hydrogen carbonate to give liquid water and carbon dioxide gas, follow these steps:
Step 1: Identify the reactants and products. In this case, the reactants are aqueous hydrogen carbonate (HCO3-), and the products are liquid water (H2O) and carbon dioxide gas (CO2).
Step 2: Write the unbalanced equation. Based on the reactants and products, you can start by writing the following equation:
HCO3-(aq) → H2O(l) + CO2(g)
Step 3: Balance the equation. Begin by examining each element and counting the number of atoms on both sides of the equation.
For hydrogen (H):
On the left side, we have one hydrogen atom in HCO3-
On the right side, we have two hydrogen atoms in H2O.
To balance the hydrogen atoms, we can add a coefficient of 2 in front of H2O on the product side:
HCO3-(aq) → 2H2O(l) + CO2(g)
Now let's balance carbon (C):
On the left side, we have one carbon atom in HCO3-
On the right side, we also have one carbon atom in CO2.
The carbon atoms are already balanced.
Lastly, let's balance oxygen (O):
On the left side, we have three oxygen atoms in HCO3-
On the right side, we have two oxygen atoms in H2O and one oxygen atom in CO2.
To balance the oxygen atoms, we can add a coefficient of 3 in front of HCO3- on the reactant side:
3HCO3-(aq) → 2H2O(l) + CO2(g)
Now the equation is balanced, showing that three moles of aqueous hydrogen carbonate react to form two moles of liquid water and one mole of carbon dioxide gas:
3HCO3-(aq) → 2H2O(l) + CO2(g)
