In this experiment I will investigate the temperature of 50cm³ of water before and after I have added calcium chloride‚ I will gradually increase the amount of calcium chloride by 1 gram to see if there is a significant change. When Calcium Chloride is mixed with water it performs an exothermic reaction which makes new bonds between the salt (Calcium Chloride) and the water. This will therefore make the solution of the reaction increase in temperature. Exothermic reactions transfer energy

History of Calcium- Calcium is a very interesting element that has a lot to tell about itself. There is much history to be learned about calcium. Calcium was actually discovered by Humphry Davy in 1808. Calcium’s name happens to come from the latin ‘calx’ meaning lime. Lime (calcium oxide‚ CaO) was a useful material that was created by heating limestone. Before the discovery of calcium‚ a man named Antoine Lavoisier classified the lime as “earth” because it was very difficult‚ almost

Milk is Unhealthy Milk has been considered a main ingredient in child development‚ but what if it is the other way around. Milk‚ the pillar of nutrition for americans‚ the U.S produces 196 billion pounds which is 23 billion gallons a year and that is only from the U.S. Milk‚ as most people know comes from cows as it is mass produced in the U.S. Since the U.S produces so much milk it is obvious why the U.S has so many dairy products. Some products sold with dairy could be cheese‚ butter‚ cottage

SCH 3U0 May 7th 2013 Percent Yield of Calcium Carbonate Introduction: The purpose of this experiment is to examine the percent yield of a precipitate in a double displacement reaction. A solution of calcium citrate and sodium carbonate were mixed together‚ then the products were filtered out as so only the precipitate remained. The filtered paper was then dried and the mass of the precipitate in the experiment divided by the theoretical mass of the precipitate from the calculated gave the

Abstract: Milk plays a very important role in meeting the day to day nutritional needs and requirements of a human being. It is a fulfilling product which provides the body with all the essential nutrients. In today’s world there is a lot of contamination in each and every food item which is the cause of many diseases spreading in humans. Milk contains a bulk of casein molecules which play a very important role in microbiology and pharmaceuticals. The samples of milk were collected from the market

the capacity of handling 2000 litres of milk per day was established at Lahirimohanpur‚in the district of Pabna(now Sirajgang district) established in the year 1946.The name of the organization was National Nutrients Co.Ltd. with the target to sell the processed milk and milk products in Kolkata(India) as the city had railway link.But the idea could not be materialized due to the partition of India during independence in the year 1947.Afterwards Eastern Milk Products Ltd.emerged under the brand name

This is because casein is a protein which is present in milk and gives milk its white colour.

Rate of Decomposition of Calcium Carbonate Theory Calcium carbonate‚ CaCO3‚is one of the most abundant minerals on the Earth. More than 4% of the Earth’s crust is composed of calcium carbonate. It is a major component in limestone‚ marble‚ seashells‚ bedrock‚ etc. Limestone and marble have been among the most widely used building materials for more than 5 000 years‚ from the pyramids in Egypt to the Parthenon in Greece and the Taj Mahal in India. In many places‚ limestone is also the foundation
