Different pollutants released from the vehicles would cause different impacts to the human body. The first one is Nitrogen oxides (NOx). When the fuels are burning at a very high temperature combined with the electric sparks in the vehicles causing the nitrogen and oxygen in the atmosphere combined together but then the formation of nitrogen oxide will react with the oxygen to form nitrogen dioxide(NO2) rapidly. If people inhaled a low level of NO2‚ the gas will irritate your eyes‚ nose‚ throat‚ and lungs

Sulfur Cycle Sulfur (S)‚ the tenth most abundant element in the universe‚ is a brittle‚ yellow‚ tasteless‚ and odorless non-metallic element. It comprises many vitamins‚ proteins‚ and hormones that play critical roles in both climate and in the health of various ecosystems. The majority of the Earth’s sulfur is stored underground in rocks and minerals‚ including as sulfate salts buried deep within ocean sediments. The sulfur cycle contains both atmospheric and terrestrial processes. Within the

Oxides Research 1. Assess evidence‚ which indicates increases in atmospheric concentration of oxides of sulfur and nitrogen. Thorough collection of data‚ surveys‚ and tests from the 1950’s indicate a rising trend in atmospheric concentrations of oxides of sulfur and nitrogen. An enhancement in funding‚ technological and information resources‚ has led to wider and more detailed analyses of oxides of sulfur and nitrogen concentrations‚ and as the diagrams indicate (see diagrams) there is a clear

Sulfur Physical and chemical properties: Sulfur is classified as an odourless‚ tasteless‚ soft‚ light yellow solid. It is insoluble in water‚ but is soluble in carbon disulfide. Sulfur is very reactive; it reacts with all metals except gold and platnium‚ forming sulfides. It also forms compounds with various non-metallic elements. Sulfur forms over 30 solid allotropes. Sulfur is a chalogen (group 16 of the periodic table) and a non metal. Sulfur’s atomic weight is 32.06. It has 16 electrons‚ protons

INVESTIGATION investigating the properties of Period 3 oxides Aim The purpose of this experiment is to examine the oxides of Period 3 elements and describe their bonding and structure. Introduction You carry out an investigation along similar lines to the work you did on the chlorides of the elements in Period 3 (Experiment 4.12). However‚ you will not be asked to test the oxides with cyclohexane because unlike the covalent chlorides‚ most of the oxides are not composed of discrete molecules. Therefore

Since we know the shape of the molecule and the bond polarities are not identical‚ the molecule is polar (or has a net dipole moment). Let’s look at the Lewis structure in the SO3 molecule. In SO3 sulfur has 3 double bonds with oxygen. Sulfur also has no lone pairs. Since there are 3 effective pairs of electron density‚ it takes sp2 hybridization. There are no lone pairs so it takes a trigonal planar shape. The bonds are identical and symmetrical. This results in a molecule

Silicon dioxide (SiO2) is one of the most common oxides on the surface of earth. Like most oxides‚ it adopts a polymeric structure. Оксидите се хемиски соединенија што содржат најмалку еден атом на кислород и еден атом од друг хемиски елемент во својата формула. An oxide /ˈɒksaɪd/ is a chemical compound that contains at least one oxygenatom and one other element[1] in its chemical formula. Metal oxides typically contain an anion of oxygen in the oxidation state of −2. Most of the Earth’s crustconsists

The element I pick for my project is Sulfur (Sulphureum). The atomic number is 16‚ the atomic mass is 32.065‚ and it is located at period number 3‚ group number 16 and group name; Chalcogen. Sulfur is by far one of the tenth most abundant elements in the universe‚ the types of abundant elements in this universe would include of Hydrogen‚ helium‚ oxygen and more. Sulfur was founded or well convinced it was an element in around the 1777‚ by Antoine Lavoisier‚ who was a French nobleman and chemist.

The Nitrogen Cycle Nitrogen fixation Atmospheric nitrogen must be processed‚ or "fixed" to be used by plants. Some fixation occurs in lightning strikes‚ but most fixation is done by free-living or symbiotic bacteria. These bacteria have an enzyme that combines gaseous nitrogen with hydrogen to produce ammonia‚ which is then further converted by the bacteria to make their own organic compounds. Conversion of N2 The conversion of nitrogen (N2) from the atmosphere into a form readily available
