GIVE EVIDENCE: chemistry in daily life
Defenition :
evidence is evidence which serves to either support or counter a hypothesis Such evidence is expected to be empirical evidence and interpretation in accordance with something method. Standards for something evidence vary according to the field of inquiry, but the strength of something evidence is generally based on the results of statitical analysis and the strength of something controls.
In daily life :
Chemistry is a big part of your everyday life. You find chemistry in daily life in the foods you eat, the air you breathe, cleaning chemicals, your emotions and literally every object you can see or touch. Here's a look at 10 examples of everyday chemistry. Some common chemistry may be obvious, but others might surprise you.
1.Elements in the Human Body
Your body is made up of chemical compounds, which are combinations of elements. While you probably know your body is mostly water, which is hydrogen and oxygen
2. Soap clean
Soap is a chemical that mankind has been making for a very long time. You can form a crude soap by mixing ashes and animal fat. How can something so nasty actually make you cleaner? The answer has to do with the way soap interacts with oil-based grease and grime.
3. Photosynthesis Is a Reaction To Make Food
Plants apply a chemical reaction called photosynthesis to convert carbon dioxide and water into food (glucose) and oxygen. It's one of the most common everyday chemical reactions and also one of the most important since this is how plants produce food for themselves and animals and convert carbon dioxide into oxygen.
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
4. Rust Is a Common Chemical Reaction
Here is the chemical equation for the rusting of iron:
Fe + O2 + H2O → Fe2O3. XH2O

Hi demi,
BalasHapusI want ask you,
Are there other chemical compounds in our body other than water and oxygen ?
Almost 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium. All 11 are necessary for life. The remaining elements are trace elements, of which more than a dozen are thought on the basis of good evidence to be necessary for life.
HapusPlease you explain why your give example eggs rotting in it ?
BalasHapusI don't understand about your question ,please write again with good langue😁
Hapus
BalasHapusWhy photosynthesis requires light?
The overall chemical reaction involved in photosynthesis is: 6CO2 + 6H2O (+ light energy) C6H12O6 + 6O2.
HapusLight is, thus, necessary for the process of photosynthesis to provide energy for the synthetic reactions.
Explain how to cope with the event of acid rain?
BalasHapusUsing fuels that contain less pollutants. Until now Indonesia is very dependent on petroleum and coal, while petroleum is a source of fuel with high sulfur content. The use of natural gas will reduce the emission of acid-forming substances.
Hapuscan you Give me examples of common chemical reactions in daily life?
BalasHapusThanks rini
HapusAerobic cellular respiration is the opposite process of photosynthesis in that energy molecules are combined with the oxygen we breathe to release energy needed by our cells plus carbon dioxide and water. Energy used by cells is chemical energy in the form of ATP.
Here is the overall equation for aerobic cellular respiration:
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (36 ATPs)
More example please you read my write on
What reaction happen if I spray oil to motorcycle chain?
BalasHapusNo reaction occurs, except the chain in the rust. While the oil here serves as a chain cleaner
HapusLubricating your chain is certainly one of the easiest maintainance tasks for a motorcycle owner, however I frequently wonder how necessary it really is.
What factors cause photosynthesis do not occur ?
BalasHapusThe three main things affecting the rate of photosynthesis are:
HapusLight
Temperature
Carbon dioxide
In addition to the three main factors above are other factors such as chlorophyll concentration, water and pollution. Only the three main factors identified above will be considered in further detail
Please explain what is used in photosynthesis process?
BalasHapusPhotosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight into chemical energy.
BalasHapuswhat chemical reactions are present on soap clean ?
BalasHapusFatty acids are the components of fats and oils that are used in making soap. They are weak acids composed of two parts:
BalasHapusA carboxylic acid group consisting of one hydrogen (H) atom, two oxygen (O) atoms, and one carbon (C) atom, plus a hydrocarbon chain attached to the carboxylic acid group. Generally, it is made up of a long straight chain of carbon (C) atoms each carrying two hydrogen (H) atoms.
Soaps are sodium or potassium salts of long chain fatty acids. When triglycerides in fat/oil react with aqueous NaOH or KOH, they are converted into soap and glycerol. This is called alkaline hydrolysis of esters. Since this reaction leads to the formation of soap, it is called the Saponification process.
