What will happen if a solution of sodium hydrocarbonate is heated give the equation of the reaction involved.

1 answer:

7 0

If heated, a decomposition reaction takes place. Sodium hydrocarbonate decompose to sodium carbonate, carbon(IV) oxide and water.

Balanced chemical equation of heating sodium bicarbonate:

2NaHCO₃ → Na₂CO₃ + CO₂ + H₂O

NaHCO₃ is sodium hydrocarbonate

Na₂CO₃ is sodium carbonate

CO₂ is carbon(IV) oxide

H₂O is water

This is chemical change (chemical reaction), because new substances are formed (sodium carbonate, carbon(IV) oxide and water), the atoms are rearranged, so there is no sodium bicarbonate (NaHCO₃) in the test tube.

Decomposition is reaction where one substance is broken down into two or more simpler substances.

Look up the active ingredient in baking soda. Write a molecular and net ionic equation when that active ingredient is mixed with

Volgvan

Answer:

The active ingredients in baking soda (NaHCO3) are

$Na^+$ and $HCO3^-$

when Baking soda reacts with Acetic acid

Molecular equation

NaHCO3(aq) + CH3COOH(aq) → Na(CH3COO)(aq) + CO2(g) +H2O(l)

Ionic equation

$Na^+ + HCO3^- + CH3COOH$ → $Na^+ + CH3COO^- +CO2 + H2O$

as $Na^+$ is present on both sides so it will cancel out and the net ionic equation will be

$HCO3^-(aq) + CH3COOH(aq)$ → $CH3COO^-(aq) + CO2(g) + H2O(l)$

Which three groups of the periodic table contain the most elements classified as metalloids (semimetals)?

attashe74 [19]

The metalloids are mostly concentrated in groups 14, 15, and 16. (Some simpler charts will show them as 4A, 5A, and 6A - take a look at the top of the periodic table your class uses to double-check).

What are the starting materials in a chemical reaction called?

Irina18 [472]

A chemical reaction is the process in which atoms present in the starting substances rearrange to give new chemical combinations present in the substances formed by the reaction. These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.
