Baking Project
There are several chemical reactions taking place in the general baking of cakes.
Every ingredient has its own function and causes a different reaction
Synthesis:
* Egg yolks (modify molecule’s structure) helps the oil-based and water-based components of the cake mix together. When eggs are cooked, the protein molecules become uncurled when exposed to heat and create new molecular bonds with other nearby protein molecules. When the egg is completely cooked, it helps form a protein network that gives the cake structure. Denaturing of egg white when it cooks is also a chemical reaction (if this does not happen the bread will have not have shape)

Baking powder:
Baking powder has two chemical reactions which are the following:
1. When it is mixed with wet ingredients it reacts to add co2
2. But that is not all when it hits the oven it reacts to the heat as well.

Double Replacement:

Baking soda (NaHCO3) reacts with acidic substances (HA) in cake batter in a double replacement reaction: Reactant Product
NaHCO3 + HA --> Na A + H (HCO3)
H(HCO3) is more commonly known as H2CO3.
Decompose:
* Gas is Produced * Yeast breaks down glucose to release CO2 gas, decomposition * Baking soda Releases CO2 according to the equation 2NaHCO3 → Na2CO3 + CO2 + H2O However, as this also produces a strong base, Na2CO3, which has to be neutralized, baking powder is usually used instead.
Baking powder is baking soda with acid added. This neutralizes the base and produces more CO2 according to the following equation:

Reactant Product NaHCO3 + H+ → Na+ + H2O + CO2
In baking powder, the citric acid is the dry ingredient that reacts with the baking soda, the CO2 gas is used in making baked products raise.
Citric acid+ NaHCO3---> CO2 gas + water + sodium citrate
(if this does not happen the bread will have not raise)

Flour: absorbs the liquid ingredients and

    Chemistry (the etymology of the word has been much disputed)[1] is the science of matter and the changes it undergoes. The science of matter is also addressed by physics, but while physics takes a more general and fundamental approach, chemistry is more specialized, being concerned with the composition, behavior (or reaction), structure, and properties of matter, as well as the changes it undergoes during chemical reactions.[2] It is a physical science which studies various substances, atoms, molecules…
