third reaction‚ ammonium carbonate was heated to decompose into two gases‚ due to the absence of anything solid or liquid following the reaction. A wood splint was used to determine that carbon dioxide was present‚ since the lit splint was extinguished when put in the test tube. Therefore‚ the other product is ammonium oxide. The fourth reaction occurred between calcium carbonate and hydrochloric acid. When mixed‚ the two reactants produced a clear aqueous solution‚ calcium chloride‚ water‚ and a gas

Gerona‚ Evelyn Chemical Reactions Experiment No. 7 Date Performed: Feb. 17‚ 2014 Date Submitted: Feb. 24‚ 2014 Mrs. Vitancol I. Theoretical Framework A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Classically‚ chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms‚ with no change to the nuclei (no change to the elements present)‚ and can often

Introduction The purpose of this lab is to find out which osmotic environment the eggs are in while sitting in different liquids. There are three different types of environments: hypotonic‚ isotonic‚ and hypertonic. Hypotonic solution causes the cell to swell until it bursts. Hypertonic solution causes the cell to shrink or to lose weight. Isotonic solution doesn’t cause the egg to shrink or swell‚ it keeps the cell the same it’s just in a different environment. The hypothesis for the egg in

falls and sinks into the ground. As the rainwater continues into the ground‚ it meets with the limestone. Limestone is mostly made up of the mineral calcium carbonate (CaCO3)‚ which is not very soluble‚ so the rocks don’t dissolve very quickly. But‚ if you add an acid‚ you add hydrogen ions (H+)‚ which will react with the carbonate to form hydrogen carbonate (HCO3- ions)‚ which are extremely soluble in water‚ therefore the limestone will start to dissolve. In the USA‚ sinkholes tend to occur in Florida

For the seventh experiment we will be performing different type of test to see how different chemical react with each other. The first experiment will be a demonstration the professor will give to the class. the first experiment you will be performing will include a test tube you will add a couple drops of dilute hydrochloric. you will add this to five little pieces of zinc metal. In next experiment you will performed you will put 2 ml of 3% hydrogen peroxide solution in a test tube .you will also

produce carbonic acid and carbonate ions thus‚ decreasing the pH. Ocean acidification affects the ecology of everything on this planet. Mainly‚ the marine ecosystems and small organisms take a large hit from the increases in temperature and carbonic acid concentration. The acidification causes reductions in ecological niches and brings about evolutionary processes with harmful outcomes. Shells in the ocean have calcification impeded by the increasing carbonic acid and carbonate ion concentration. The

PLANT CELL Introduction Plant cell is the basic unit of structure and function in nearly all plants. The range of specialization and the character of association of plant cells are very wide. In the simplest plant forms a single cell constitutes a whole organism and carries out all the life functions. In just slightly more complex forms‚ cells are associated structurally‚ but each cell appears to carry out the fundamental life functions‚ although certain ones may be specialized
