KHCO3(s)+ HBr(aq)→
Express your answer as a chemical equation. Identify all of the phases in your answer.
Sure, here's a chemical equation for the reaction:
KHCO3(s) + HBr(aq) → KBr(aq) + H2O(l) + CO2(g)
In this equation, the phases are indicated in parentheses. So, (s) indicates a solid, (aq) indicates an aqueous solution, (l) indicates a liquid, and (g) indicates a gas. In this case, KHCO3 is a solid, HBr is an aqueous solution, KBr is also an aqueous solution, H2O is liquid, and CO2 is a gas.
The balanced chemical equation for the reaction between KHCO3(s) and HBr(aq) is:
2 KHCO3(s) + 2 HBr(aq) → K2CO3(aq) + 2 H2O(l) + 2 CO2(g) + Br2(aq)
In this equation, KHCO3(s) and HBr(aq) represent the solid potassium bicarbonate and the aqueous hydrobromic acid, respectively. K2CO3(aq) represents the aqueous potassium carbonate, H2O(l) stands for liquid water, CO2(g) represents gaseous carbon dioxide, and Br2(aq) represents aqueous bromine.
To express a chemical equation, we need to identify the reactants and products and indicate their corresponding states or phases (solid, liquid, gas, or aqueous).
In the given reaction:
Reactants: KHCO3(s) and HBr(aq)
The reactant KHCO3 is a solid, so we write it as (s) to represent the solid state. The reactant HBr is an aqueous solution, so we write (aq) to represent the aqueous state.
To write the chemical equation, we simply separate the reactants and products using an arrow (→), indicating the direction of the reaction:
KHCO3(s) + HBr(aq) →
