world’s ice is slowly melting‚ so that also means our glaciers are melting (shrinking). This is a problem worldwide. The oil‚ coal‚ natural gases‚ and fossil fuels we burn affect our atmosphere and increase the temperatures that melt our glaciers. If the glaciers continue to melt rapidly ocean levels will rise‚ there will be flooding‚ there also could be droughts. This is a very serious issue today but I’m just going to tell you about two places for now. How does the melting of glaciers affect people

Experiment (6) Determination of ash content Aim: To determine the ash content in 5 samples of milk Principle: This experiment wills comparison between all samples. We will weight three times. First type the weight of crucible. The second is crucible and the sample the last about the weight of ash after removing from furnace. Apparatus: 1. clean crucibles 2. Analytical balance 3. Clean tongs 4. Tripod 5. Bunsen burner 6. Silica triangle Instruments: 1. Furnace Procedure:

CHEM 1105 Experiment 4: Determination of a Chemical Formula Introduction When atoms of one element combine with those of another‚ the combining ratio is typically an integer or a simple fraction. The simplest formula of a compound expresses that atom ratio. When two or more elements are present in a compound‚ the formula still indicates the atom ratio. To find the formula of a compound we need to find the mass of each of the elements in a weighed sample of that compound. For example‚

the melting glaciers poses a direct threat to my home. Island nations and coastal cities will suffer the inevitable if we do not act now. In six degrees‚ Mark Lynas warned the impending arctic tipping point‚ once passed‚ the melting of the glaciers cannot be reversed‚ leading to a loss of habitable environment. However‚ I believe that the situation is worse than what Lynas anticipated. Despite some efforts from the international to curb the increasing carbon emissions‚ glaciers are melting faster

Investigating the effects of acid rain in the growth of cress seedlings IntroductionAcid rain is rain or any other form of precipitation‚ which is unusually acidic. It has harmful effects on plants‚ animals and buildings. Acid rain is mostly caused by human emissions of sulphur and nitrogen compounds which react in the atmosphere to produce acids. Acid rain can slow the growth of vulnerable forests and cause leaves and needles to turn brown and fall off. In addition‚ it depletes minerals from the

Acid: A chemical substance (typically‚ a corrosive or sour-tasting liquid) that neutralizes alkalis‚ dissolves some metals‚ and turns litmus red. Ionic Dissociation: Dissociation in chemistry and biochemistry is a general process in which ionic compounds (complexes‚ or salts) separate or split into smaller particles‚ ions‚ or radicals‚ usually in a reversible manner. Strength of Acids: The strength of an acid refers to its ability or tendency to lose a proton. There are very few strong acids. A

Our Iceberg is Melting: Changing and Succeeding Under Any Conditions John Kotter and has produced a great book that contains a wealth of wisdom and insight. While it looks and reads like a simple book‚ it is anything but simple. The message which Kotter is able to make clear goes much deeper than the surface story of a colony of penguins in search of answers pertaining to their survival on an iceberg. He easily describes a scenario through a penguin colony that any person can relate to and think
