The Environmental Impact of Carbon Dioxide (CO2) Carbon Dioxide (CO2)‚ a chemical made up of one carbon atom and two oxygen atoms‚ is a non-flammable‚ odorless and colorless gas that exists naturally in the atmosphere. CO2 is one of the greenhouse gases‚ amongst methane‚ nitrous oxide and other gases‚ which keeps the Earth’s temperature habitable (UCAR). Without it‚ the Earth will be inhospitably cold. However‚ ever since the mid-nineteenths century‚ humans have significantly increased the amount

Find the probability that she did not hit a boundary. Answer: Number of times the batswoman hits a boundary = 6 Total number of balls played = 30 Number of times that the batswoman does not hit a boundary = 30 − 6 = 24 Question 2: 1500 families with 2 children were selected randomly‚ and the following data were

Deforestation The “Slashing and burning” of rainforests has to stop. The deforestation of our rainforests is effecting our environment and us more than you may think. We get the oxygen we need from trees‚ forests protect us from Carbon Dioxide‚ and forests protect most of Earth’s plants and animals. We need trees to breathe and rainforests to protect us from harsh things that we emit from our bodies. Many rainforests help and protect us. “More than 20% of the world’s oxygen comes from the Amazon”

baking soda hit the vinegar and lemon juice‚ the balloon started to expand.Adding the lemon juice to the baking soda creates a chemical reaction. The baking soda is a base‚ while the lemon juice is an acid‚ when the two combine they create carbon dioxide (CO2). The gas rises up and escapes through the soft drink bottle‚ it doesn’t however escape the balloon‚ pushing it outwards and blowing it up.

The reaction also makes small amounts of toxic sulphur dioxide gas. You will choose one factor and investigate this factor’s effect on the rate of reaction between sodium thiosulfate and dilute hydrochloric acid.

recognizes sulfur as a contributor to the acid rain problem and enacted a goal to reduce total national sulfur dioxide emissions to half of 1990 levels. The Act describes the cap and trade approach whereby companies are permitted to pollute a certain amount of sulfur dioxide compared to levels of electricity output they produce. Rainwater is naturally acidic with a pH of around 5.7. Acid rain can be defined by anthropogenic acidification caused by nitrogen compounds and sulfur dioxide‚ formed

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
