Chemical reactions are changes in
elements or chemical compounds so that other compounds occur because of the
loose element. The compounds or the initial compounds involved in the reaction
are referred to as reactants. Different chemical reactions are used together in
chemical synthesis to produce the desired product of the compound. There are
many chemical reactions in everyday life, including:
1.Burning
Every time we light a match, burn a candle, make a fire, or light a grill, we will see a burning reaction. Combustion combines energetic molecules with oxygen to produce carbon dioxide andwater.For example, propane combustion reactions, found in gas grills and some fireplaces, are:
C3H8 + 5O2 → 4H2O +
3CO2 + energy
2. Mixing Chemical
If we just combine vinegar and baking
soda to make chemical volcanoes or milk with baking powder in a recipe, we
experience the displacement or double reaction metathesis (plus some other
things). The material recombines to produce carbon dioxide and water gases. The
carbon dioxide forms a bubble in the volcano and can help increase roasting.
These reactions seem simple in practice, but often consist of several steps.
Here is the overall chemical equation for the reaction between baking soda and
vinegar :
HC2H3O2 (aq) + NaHCO3
(aq) → NaC2H3O2 (aq) + H2O (s) + CO2 (g)
3.Photosynthesis
Photosynthesis is a process used by plants and other organisms to convert light energy, usually from the Sun, into a chemical energy that can then be liberated to fuel organism activity. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water. Plants produce food for themselves and animals and convert carbon dioxide into oxygen.
6 CO2 + 6 H2O + light
→ C6H12O6 + 6 O2
4. Aerobic Respiration
Aerobic cellular respiration is the
reverse process of photosynthesis in molecular energy coupled with the oxygen
we breathe to release the energy needed by our cells plus carbon dioxide and
water.
C6H12O6 + 6O2 → 6CO2 +
6H2O + energy (36 ATPs)
5. Anaerobic Respiration
Anaerobic respiration describes a set of
chemical reactions that allow cells to gain energy from complex molecules
without oxygen. Cell muscles perform anaerobic respiration every time we get
rid of oxygen which then reaches them, like during intense or prolonged
exercise. Anaerobic respiration by yeast and bacteria used for fermentation, to
produce ethanol, carbon dioxide, and other chemicals that make cheese, wine,
beer, yogurt, bread, and many other common products. The overall chemical
equation for one form of anaerobic respiration is:
C6H12O6 → 2C2H5OH +
2CO2 + energy
6. Rust
Rust is iron oxide, usually a red oxide formed by redox reactions of iron and oxygen in the presence of water or air humidity. Rust is a general term for corrosion of iron and its alloys, such as steel. Many other metals have equal corrosion, but the resulting oxide is not commonly called rust.
Here is the chemical equation for iron rust:

Saponification
The
saponification reaction is a hydrolysis reaction of fats / oils by using strong
bases such as NaOH or KOH to produce glycerol and fatty acid salts or soaps. To
produce a hard soap is used NaOH, while to produce a soft soap or liquid soap
used KOH. The difference between hard and soft soap when viewed from its
solubility in water is hard soap is less soluble in water when compared with
soft soap.
What distinguishes facial soap and body soap? And what is the reaction between them?
BalasHapusCommercial bath soaps generally contain many chemicals such as petroleum, synthetic chemicals, and petrochemicals that can damage the skin. One thing that disguises face soap and body trait is its acidity level.
HapusThe facial skin has a pH range of 4.0 to 5.5, slightly lower than the skin pH of the body that has a pH close to 7 or neutral.
What is the negative impact from burning?
BalasHapusBurning can cause environmental pollution problems, especially air pollution
HapusWhat factors have no effect on increasing photosynthesis activity?
BalasHapusO2 because the addition of O2 air does not affect the speed of photosynthesis.
HapusIn chemical mixing, what if you mix NaOH with hot water? What happened?
BalasHapuswhy the iron can be rusted?
BalasHapusSpecifically, the main cause of iron corrosion is oxygen and water. Rust on iron occurs because the humid air (oxygen and water) corrode (react) to the iron so that new substances appear solid reddish brown substance.
HapusWhat is the anaerobic respiration chemical equation?
BalasHapusThe overall chemical equation for one form of anaerobic respiration is:
HapusC6H12O6 → 2C2H5OH + 2CO2 + energy
How does the chemical reaction process in the human body?
BalasHapusMetabolism
HapusOrganic processes that occur in the human body are called metabolism, which involves a large number of chemical reactions. Enzymes secreted by different organs act as biocatalysts that accelerate the rate of reaction, while the hormone regulates time and speed.
Our wellbeing, smooth function and normal health depend on metabolic processes. The coordination and simultaneous occurrence of this process of life in an orderly manner is the reason we are fit, healthy and alive.
"If we just combine vinegar and baking soda to make chemical volcanoes or milk with baking powder in the recipe, we experience a displacement or a double metathesis reaction" would you please explain what is a metathesis double reaction?
BalasHapusThe reaction of metathesis or multiple exchange reactions is a reaction involving the exchange of parts of the reactants. If the reagents are ionic compounds in solution form, the exchange portion is the cation and anion of the compound. For example a colorless potassium iodide solution is mixed with lead (II) nitrate solution which is also colorless. The ions in the solution react to form a yellow precipitate of the lead (II) iodide compound. The equation of the reaction:
Hapus2KI (aq) + Pb (NO3) 2 (aq) → 2KNO3 (aq) + PbI2 (s)
What is the impact if we combine the two solutions without following the guidance?
