NaHCO3 dissolves in water and makes it slightly alkaline due to the reaction
NaHCO3 + H2O= NaOH + H2CO3
in ionic terms
HCO3- + H2O = OH- + H2CO3
is this a physical change or a chemical change
Citric acid is tri-basic, so C6H8O7 is best written as H3(C6H5O7)
6 K+HCO3- + 2 H3(C6H5O7) --> 3 H2O + 6 CO2(g) + 2 (K+)3(C6H5O7)-
The formation of sodium citrate, water and carbon dioxide.
The soluble in water sodium citrate is formed; carbon dioxide is evolved.
Chemical change.
You have half answered this question for yoiurself ( produced) ; the answer is 'PRODUCTS'.
The chemical or chemicals formed in a chemical reaction are called the product of the chemical reaction.
The new and different substances formed as a result of a chemical change (reaction) are the products of the reaction.
what would most likely result in the greatest decrease in the rate of a chemical reaction
yes. there is a chemical reaction between sodium bicarbonate and lime. lime contains ascorbic acid (vitamin c) and sodium bicarbonate is an alkali therefore when they are combined neutralization takes place. isn't neutralization a chemical reaction? OOPS - you are confusing lime the fruit with lime (CaO). You are also confusing ascorbic acid (very weak) with citric acid, the dominant acid in the fruit. As for the reaction between oxide ion and bicarbonate, likely the result is hydroxide ion and carbonate ion. Bicarbonate is weakly amphiprotic.
It does not react with water, but simply dissolves in it - a physical, not chemical, reaction.
is a substance that forms as a result of a biological- or chemical reaction
Chemical change.
Products are the new substances that form as a result of a chemical reaction.
A reaction product.

The chemical or chemicals formed in a chemical reaction are called the product of the chemical reaction.
A chemical change, also known as a chemical reaction, will result in one or more products with new chemical properties.
Fire is the result of an oxidation reaction.
A reaction has two components with the reactant as an "ingredient," and the product is the end result. A combustion reaction as the reactants of O2 (oxygen) and CH4 (methane). Their product through the reaction CH4 + 2O2 is 2H2 (water) and C02 (carbon dioxide).
The new and different substances formed as a result of a chemical change (reaction) are the products of the reaction.
