Combustion


Definition: rapid chemical combination of a substance with oxygen, involving the production of heat and light.
Combustion is an exothermic reaction because it releases energy through light or heat.
The product of combustion reaction is heat.
It is a type of redox reaction.
what is a Redox reaction? Oxidation reduction or redox reaction is a type of chemical reaction in which the oxidation number of  molecule, atom, or ion changes by gaining or losing an electron.
Examples of combustion reactions include:
"2 H2 + O2 → 2H2O + heat
CH4 + 2 O2 → CO2 + 2 H2O + heat"

A few real life examples of combustion could be: 
  1. BBQ's
  2. Gas ovens
  3. Forest fires
  4. Bonfires
So this is applicable to our life because sometimes we use combustion to our benefit for example"BBQ's" and "Bonfires".

Precipitation

Precipitation Precipitation is any forms of particles, whether liquid or solid, that Precipitation reaction leads to a reaction  that leads to the formation of a heavier solid in a lighter liquid. Precipitation is basically any product of the condensation of the atmospheric water vapor that falls under gravity. This occurs when a portion of atmosphere becomes saturated with water vapor. There are two processes, possibly acting together, can lead to the air and it becomes saturated. Cooling the air or adding water vapor to the air. Precipitation  forms as smaller droplets coalesion with other rain drops or ice crystals within a cloud. Short periods of rain  in scattered location are named showers. An example: Mixing silver nitrate and sodium chloride in water will cause silver chloride to precipitate out of   solution   as a   solid . In this example, the precipitate is silver chloride. When writing a chemical reaction, the presence of a precip...

Condensation

What is it?  This process is like the opposite of evaporation. This is a process the water vapor (Clouds: A form of water that we can see) in the air change into liquid state. This process is part of the water cycle because it is responsible for the recreation of the clouds. The clouds create precipitation  which is the water that is realized from the cloud in the form of rain After turning into liquid state the water,snow,sleet or hail (which the last three have similarities and not much a difference). This is a primary route were the water has to return to the earth surface which is part of the water cycle.                            They are part of precipitation because they are forms of precipitation The atmosphere must be fully saturated before condensation takes place. In other words the maximum amount of pressure on the vapor must be reached. When this happens the vapor has no choice but to...

Compostable Bioplastics

Compostable Bioplastics Bioplastics are plastics that decompose naturally in the environment. They are often used as compostable materials because they can also decompose in soil that is very good because it can due to the bacteria in the plastic. According to a study in Germany, many composts made from kitchen and garden waste contain microplastics, which are then found in the fields. This is a problem that happened in several different European countries like (France, Spain, Switzerland). Here in Cameroon composting is not a common thing so won’t be such a problem but I believe it will be a positive thing for countries in development like Cameroon because most of the food to compost in Cameroon do not have plastics they are mostly natural but if plastic was compost it would be used with bioplastics and will make Cameroon increase their economy and lower pollution in the country. Nutrients for agriculture: The recovery of organic waste is undeniably a go...
