clue about my eating habits‚ and how to go about eating “properly.” For instance‚ I always assumed that I had been consuming too much fat‚ and I was unsure of the difference between good (monounsaturated and polyunsaturated) fats‚ and bad (saturated) fats. According to the calculations for day one of my food log‚ only 16.5% of total calories from fat were being taken in‚ whereas I should have been consuming anywhere from 20%- 35%. In addition to the lack of fats that I was consuming on

Aldol Condensation Formal Abstract: An aldol condensation reaction was performed on acetophenone using p-anisaldehyde and sodium hydroxide as a base. This produced trans-p-anisalacetophenone in the form of a fluffy yellow crystal. The reaction was performed in a test tube and sodium hydroxide was added drop by drop followed by recrystallization and vacuum filtration. In order to verify the presence of the ketone 2‚4-dinitrophenylhydrazone was synthesized and reacted with trans-p-anisalacetophenone

predict that the metal will be the most reactive with hydrocholoric acid is calcium because calcium is in Group 2 which is the alkaline earth metals in the periodic table and because calcium is at the extreme left side of the periodic table and as you go across a period‚the element change from reactive metals on the left to non reactive metals on the right.On the extreme right of the periodic table is the noble gases.Also calcium is Group 2 which is the alkaline earth metals and they are part of the reactive

enough‚ if using fat spread‚ choose a reduced fat variety and spread thinly. When choosing prepared products‚ check the label and choose those products lower in fat. Saturated fat A diet low in saturated fat can prevent high cholesterol and decrease the risk of coronary heart disease‚ diabetes and some cancers. Sources of saturated fats are Butter‚ lard‚ cream‚ coconut oil or cream‚ palm oil‚ mayonnaise‚ salad cream and some margarines.

Galvanized Nails Introduction. In this experiment the mass of zinc on galvanized iron nails was calculated to determine the appropriate price that should be charged to coat a nail with zinc (galvanize) it. The effectiveness of gasometric and gravimetric analysis were assessed by carrying out both methods mathematically using values determined by this experiment‚ and then comparing these values using their percent differences. The mass of zinc found on each nail can then be used to determine how

I. Introduction The purpose of this experiment is to determine the pH values of acids‚ bases‚ and buffers of distilled water and 10.0 buffer using measured concentrations of Sodium hydroxide (NaOH) and/or Hydrochloric acid (HCl). Acid is a compound typically having a bitter taste and capable of nullifying alkalis and releases hydrogen ion when added to a solution‚ or containing an atom that can accept a pair of electrons from a base (McKinley‚ Dean O’Loughlin‚ & Stouter Bidle‚ 2016). Bases are water-soluble

All soils above water table are unsaturated. 3. Compacted soils are generally unsaturated soils. 4. Shear strength of a saturated clayey sand is greater than its unsaturated shear strength. Why do we need to understand Unsaturated Soil Mechanics? Most of the natural soil systems are
