Sodium chloride, otherwise known as salt, is vital in our day-to-day lives. What else would we spread on the ground in icy conditions to keep us safe from falling? Or add a pinch of into a family recipe passed down generations? Glass, plastic, and even paper contain amounts of salt. Salt is used to clean these items as well - as it is found in cleaning solvents such as detergents and bleaches. Could you imagine life without salt now? Salt is in fact the only rock we as humans eat. How did this rock
different organism lives. There are many different freshwater pollution and each one of having it one effect. One of the organism that live is fresh water is Ankistodemus, a green alga that grows in fresh water pond and lakes. When Sodium chloride (salt) is added to the alga environment what type of effect will it have on its growth? The importance of this experiment to make aware of how pollution have a stern effect on the living things around the Earth. Being alert of this will expression how putting

Introduction The number of drops a penny can hold is affected by the type of liquid. Will the number of drops on the penny until it overflows change if I change the liquid from water to sodium chloride water and by how much will it change? To investigate this, there needs to be variables that are not changed when experimenting. The penny is the dependent variable because it depends on the number of drops to overflow and the drops of the liquid the independent variable as it does not change or depend
Discussion: The purpose of the lab was to determine the percent of water in the hydrate MgSO4 * N2H0 through the process of heating the hydrate, releasing the water molecules, and leaving only the anhydrous magnesium sulfate and also determine the number of water molecules in the hydrate. Throughout the lab, various masses were tooki, including the mass of the evaporating glass with the watch glass, the mass of the evaporating glass, and watch glass with the additional hydrate sample, and the mass
Living like Salt Israelmore Ayivor once said, “Don't be a pepper on the eyes of people; Rather be the salt on their tongue and make a difference that influences their sense of belonging to the earth.” Many people hear the word salt and automatically think of a substance you put on food, but salt has numerous uses than just to season your meal. Salt is used to preserve and season food, to earn money, to confirm sacrifices in the Bible, and as a symbol of purity. Each one of the things listed all
According to their results, induction time decreased by 85% and 73.9%, and the amount of methane converted into the hydrate crystals increased by 33.7% and 7.4%. As well as Mohammadi et al., reported the effect of SDS and silver nanoparticles on the kinetics of carbon dioxide hydrate formation (Mohammadi et al., 2014). They showed that SDS and silver nanoparticles do not have significant effect on decreasing the induction time and increasing the storage capacity of CO2 hydrate, but the mixture of
Four 50-ml beakers were filled with 40 ml of distilled water, one 50-ml beaker with 50 ml of distilled water, and two 50-ml beakers with 40 ml of tap water using a graduated cylinder. Each beaker was labeled based on their pH level measured with a pH meter. A beaker with 40 ml of a pH 7 tap water was saved for positive control. A beaker with 40 ml of distilled water had a measured PH level of 5.33. One drop of 1 M HCl solution was added to a beaker containing 40 ml of distilled water to reach a PH
.. A) The Potassium Iodate solution was prepared by weighing out 0.20 grams of Potassium Iodate and added it into 100ml Volumetric Flask. After this step, the deionized water was added until the mark at the neck of the Volumetric Flask and covered with a lid. To homogenize the solution, the Volumetric flask was repeatedly inverted and shaken. Finally, the Potassium Iodate solution was ready. Next, the Sodium thiosulfate solution was prepared in a similar manner. First, 1.20 grams of Sodium thiosulfate
Salt of the World Salt is a very versatile product and has been used all throughout history. In modern times it is mainly used to season food and for beauty purposes. Although we still use salt today, in history the uses of salt varied widely across the world. During biblical times salt was considered a sacred item to obtain. In history salt has been used for cultural/traditional and purposes. To begin with, salt was used for cultural and traditional purposes in the biblical times. For example
