Lauric acid

scientific objectives of the experiment were to measure the temperature of a sample of lauric acid as it 's cooled. The data was manipulated to generate a cooling curve and freezing point. Introduction Matter can be categorized as solid, liquid, or gas this is known as phases of matter. A solid is a sample of matter with a defined volume and a defined shape; this sample is not easily compressible and doesn’t flow smoothly. A liquid has an undefined shape and a fixed volume; Liquid is not easily compressed and flows smoothly. A gas holds the shape and volume of its container, unlike the others gas flowed and compressed easily(2.02 Classifying Matter, n.d.) Changes are physical changes that only affect the appearance…

it for far longer. In short, coconut oil is great at teeth whitening because enjoying whiter teeth is just one of the benefits of coconut oil for teeth cleaning. It gives you a fantastic clean that doesn’t dry your mouth out and imparts a certain “gleam” to the surface of teeth. Is coconut oil best for teeth whitening? It’s a matter of opinion, but I believe so, and I’ll tell you more about what kind of coconut oil to look for in just a little bit (there are more varieties than you…

Soap may be made up from either saturated fatty acids and/or unsaturated fatty acids. The most common saturated fatty acids used in soap are, “lauric acid, myristic acid, palmitic acid and stearic acid” ( Michelle 2014). If a more effective clean is desired then, using a saturated fatty acid is the way to go because they get rid of oils better. Due to this, soaps made up of saturated fatty acids are less prefered for skin because it will take away the natural oils produced by your skin. These…

Whether we notice it or not, chemistry lives in our bodies. Things such as skin conditions, digestion, breathing, and hair growth all deal with chemistry in their own way. They all have certain chemical reactions and chemical changes that affect the way our bodies work. Even though we study different curriculums during chemistry such as the chemical equations, chemical reactions, and other things we have learned go far beyond what is said in class. During food digestion there are…

Saturated fats are triglycerides, consisting of three saturated fatty acids bound to a glycerol molecule. These fatty acids have only single bonds between carbon atoms and they are saturated with hydrogen atoms. Each fatty acid has linear shape, allowing for saturated fat molecules to be packed tightly. Saturated fats are solid at room temperature. Examples of saturated fats are butter, beef fat, palm oil and coconut oil. Butter actually contains a lot of unsaturated fatty acids such as oleic,…

oxygen3. Serratia Marcescens is a gram negative bacterium. Gram negative bacteria have a thin cell of a single layer of peptidoglycan that is enclosed by an outer membrane. The outer membrane is surrounded by special phospholipids composed of fatty acids called lipopolysaccharides that are attached to a glucosamine…

neutralization reaction. A neutralization reaction is a chemical reaction in which an acid and a base react to form an ionic compound (a salt) and water; the resulting pH is closer to 7. The general chemical equation for a neutralization reaction is: Acid + Base Water + Ionic Compound This can also be considered as a double displacement reaction. However, since the reacts are an acid (carbonic acid) and a base (sodium hydroxide) and the products are a salt (sodium carbonate) and water (H2O),…

than anything else. It is important to take care of the body from any harm. One thing that the body is capable of is maintaining pH levels and buffers. A pH is the power of hydrogen and buffers prevent extreme shifts in pH. The blood has a specific type of buffer that is maintained at pH level of 7.4. If the buffers shifts and levels of pH go to 7 or 7.8, it can be deadly. The blood buffer contains carbonic acid which dissociates into bicarbonate acid and hydrogen ions. This equation can also be…

Bronsted-Lowry Theory, is defined as a proton (H+) donor. An equation exemplifying an acid dissolving in water is: HCl (g) H2O H+ (aq) + Cl- (aq) A base, based on the Bronsted-Lowry Theory, is defined as a proton (H+) acceptor. An equation exemplifying a base dissolving in water: NaOH (s) H2O Na+ (aq) + OH- (aq) Molarity, also known as the concentration, is represented as moles of the measured substance divided by the volume in dm3. It is a value of the amount of substance in a…

INTRODUCTION : The concept of dentin adhesion presently used involves the nanomechanical retention which is due to polymerisation of hydrophilic monomers around acid exposed collagen fibres.1 The entanglement of these monomers within the exposed collagen fibres gives rise to the so called Hybrid layer , which is also referred as Resin infiltrated Dentin layer.2 The presence of hybrid layer is important for attainment of a leakage free interface between the cavity walls and resin composite.2…
