examples of chemical equations that occur in everyday life?

Answer 1

Taking baking soda for heartburn:
NaHCO3 + HCl----->NaCl + H2O + CO2 (burp!)

Someone left the cap off the hydrogen peroxide bottle:
2H2O2--->2 H2O + O2

Rotting eggs near fine silverware:
H2S + Ag --------> AgS (tarnish) + H2 (sounds dangerous!)

Photosynthesis (Overall reaction)
6CO2 + 6H2O--------->C6H12O6 +6O2

The same person left the cap off the bottle of ammonia:
NH4OH-------------->NH3 + H2O

Grill them burgers( Propane):
C3H8 + 5O2-----3CO2 + 4H2O

Action of yeast on sugar:
Making bread or making wine:
C6H12O6------->C2H5OH + CO2 (equation not balanced)

Rusting of iron:
4Fe +3 O2--------->2Fe2O3

Hey, that aluminum siding looks old:
4Al + 3O2------------2Al2O3

Answer 2

If chemistry were compared to a sport, then the study of atomic and molecular properties, along with learning about the elements and how they relate on the periodic table, would be like going to practice. Learning about chemical reactions, which includes observing them and sometimes producing them in a laboratory situation, is like stepping out onto the field for the game itself. Just as every sport has its "vocabulary"—the concepts of offense and defense, as well as various rules and strategies—the study of chemical reactions involves a large set of terms. Some aspects of reactions may seem rather abstract, but the effects are not. Every day, we witness evidence of chemical reactions—for instance, when a fire burns, or metal rusts. To an even greater extent, we are surrounded by the products of chemical reactions: the colors in the clothes we wear, or artificial materials such as polymers, used in everything from nylon running jackets to plastic milk containers.

Answer 3

AEROBIC RESPIRATION
C6H12O6 + 6O2 → 6CO2+ 6H2O + Energy (36 ATPs)

Photosynthesis
Photosynthesis is the process by which green plants manufacture their own food. This occurs in presence of sunlight and other raw materials, namely carbon dioxide and water. The chlorophyll pigment harvests the light energy from sunlight, which is then converted into glucose by the phenomenon of photosynthesis. In short, it is the opposite of aerobic respiration. The equation for photosynthesis is:

6 CO2+ 6 H2O + Light energy → C6H12O6 + 6 O2

Rusting of Iron
Very often, you notice a coating of rust over unpainted iron surfaces, which gradually leads to disintegration of iron. This is nothing, but a chemical phenomenon called rusting. In this case, iron (a very reactive metal) combines with oxygen in presence of water (more precisely, atmospheric moisture), resulting in formation of iron oxides. The chemical reaction behind rusting can be simply represented as:

Fe + O2 + H2O → Fe2O3. XH2O

Propane Grill
Have you ever prepared meat in a propane grill? The meat placed over the burner is cooked with the help of heat energy released after burning of propane gas. Thus, propane is the reactant which when burnt with the help of oxygen gives heat energy and other byproducts. Check out the balanced equation for the combustion reaction that take place in a propane grill:

C3H8 + 5O2 → 4H2O + 3CO2 + energy

Answer 4

Photosynthesis
Respiration
Rusting
Burning of candle wax
Curdling of milk

Answer 5

2C8H18 + 25O2 --> 16CO2 + 18H2O

That's the equation for octane burning. Happens in your car every time you use it.

Answer 6

the body burning sugar?

C(6)OxHy (its been to long since school) +O2 -> H20 + CO2

water evaporating?
H2O(liquid) -> H2O(gas)

Answer 7

your stomach digesting food
