Chemistry And Others

In this report I will talk about “Chemistry and other sciences”, for example Chemistry is the science that studies the composition, structure and properties of matter and the changes it undergoes during chemical reactions and their relation to energy.

“From the Stone Age to silicon age” it will talks about the evolution of the humans and all the changes in the world

And “The melting of polar caps threat Mexico’s climate”. In this section we are going to talk about the causes that determine the possible causes of this phenomenon and suggest alternative solutions that can contribute for solving this problem

Finally you would find descriptions, diagrams, body, reflection, conclusions and the bibliography at the end.

R.1. Chemistry is the science that studies the matter, compositions, and properties of the changes, making new things applying the technology.

Actually chemistry plays an important role in many activities for example the most common, in the Agricultural production that increased thanks of

• Chemical Fertilizer

• Pesticides

• And improved seed varieties

Pesticides are chemicals that are made to kill pests and help protect plants against molds, fungi, rodents, noxious weeds and insects.

Pesticides help prevent loss of crops and potentially increased disease in humans.

The goal of the fertilizers is to make plants grow faster, what you need to do is supply the elements that the plants need in readily available forms.

“Most fertilizers supply just nitrogen, phosphorus and potassium because the other chemicals are needed in much lower quantities and are generally available in most soils. Nitrogen, phosphorus and potassium availability is the big limit to growth. “

R.2. “From the Stone Age to silicon age”

Since the past the main characteristic of the humans has been the curiosity, thanks of it we discovered methods to transform the nature and the world.

Nowadays there are different materials characterized by great variety of applications three of them have great influence in activities developed in our daily life: cooper, silicon and oil.

• Which are the main uses of each one?

• Cooper: It is a ductile metal with very high thermal and electrical conductivity; Copper is often used to color glass. It is also one component of ceramic glaze.

• Silicon: Silicon is a chemical element with the symbol Si and atomic number 14. Silicones are used in high temperature greases and waxes,
