Sodium chloride is table salt that is commonly used in the food industries as a flavor enhancer and preservative society. Sodium chloride is also used in glass production in society. Salt helps lower the melting points of ice or snow‚ therefore they are used in cold climates to help get rid of accumulating snow or ice. Sodium chloride is normally made by

The aim of this experiment was to investigate the effects of salt type and concentrations on the rate of heating and the boiling point. Then from this data make a conclusion which salt type and concentration is the most energy efficient at heating water to its boiling point. It was hypothesised that highest concentration of MgCl2 was going to be the most energy efficient at heating the solution to its boiling point. This is because MgCl2 has the lowest specific heat capacity thus will use the least

Introduction: The importance of this lab is to get a deeper understanding of how the concepts of solutions and insolubility applies to the lab’s purpose of making chalk using precipitation reactions. A precipitation reaction is when a solid/ precipitate (insoluble) is formed when two solutions that contain soluble salts are combined. Some additional scientific concepts investigated in this lab are insolubility‚ double replacement‚ and limiting reactants. Insolubility occurs when a solute is incapable

Aldo Leopold presents many interesting aspects regarding ecology and conservation within his writing of the Land Ethic‚ Round River‚ and “Think like a Mountain”. One statement that stood out among the rest was “Harmony with land is like harmony with a friend; you cannot cherish the right hand and chop off his left". The land is much like the human body—if one part is damaged or sick‚ the effects can be witnessed elsewhere. Like a cancer that attacks the cells‚ the effect of pollution‚ overhunting

The objective of the deicer lab was to successfully conduct experiments to determine the usefulness of magnesium chloride as a deicer. To find how successful magnesium chloride is as a deicer‚ experiments were conducted to determine the freezing point depression‚ enthalpy of dissolution‚ the impact on the surrounding environment‚ and also the expenses of using magnesium chloride as a deicer. For magnesium chloride to be determined as a good deicer‚ the reaction with water needs to be exothermic so

At the beginning of the lab‚ a micro test tube with and without glass wool was weighed on an analytical balance. A watch glass‚ crucible‚ and lid were also weighed. The masses of all the materials needed for the lab were recorded in the data tables of the laboratory notebook. An unknown vial was obtained from the teacher and set to zero on the balance. About 0.6 grams of the unknown was measured into the micro test tube. The analytical balance was set to zero again and then the test tube with the

Matthew 5:13-14 How does being salt and light relate to the Beatitudes? The Beatitudes define acts of kindness and depict the qualities needed for entry into and life inside the Kingdom of God. The residents of the Kingdom exhibit these specific qualities. At the point when and as they do‚ they are salt and light. As a blessed people and the children of God‚ we are salt and light in the work environment‚ in our homes‚ and in our country. In lowliness and obedience to God‚ we work for socially
