of solubility and how different compounds interact. An example of a realistic application for density could be a (add). Experimental…

substances. The following sets of substances could have been assigned: Set 1 - Silver nitrate (AgNO3), Manganese(II) nitrate (Mn(NO3)2), Barium nitrate (Ba(NO3)2), Hydrochloric acid (HCl), Sodium Hydroxide (NaOH); Set 3 - Silver nitrate (AgNO3), Barium nitrate (Ba(NO3)2), Hydrochloric acid (HCl), Sulfuric acid (H2SO4), Sodium Hydroxide (NaOH); Set 4 - Silver nitrate (AgNO3), Lead (II) nitrate (Pb(NO3)2), Hydrochloric acid (HCl), Ammonia (NH3), Water (H2O). From the substances above Hydrochloric…

predicted that sample number 2 is the oven cleaner that contains Sodium Hydroxide. Sodium Hydroxide (NaOH) is highly corrosive due to its elements; the presence of oxygen and an electrolyte (Sodium – Na) cause corrosion, the breakdown of a metal resulting from reactions with chemicals in its environment. The oxygen oxidizes with the metal, and the sodium help speed up the corrosion process. The presence of oxygen and electrolytes (Sodium – Na) in sample number 2 make it more…

to identify an unknown compound that has been discovered in a landfill in their hometown. Once they identified the compound, they would then have to determine both the chemical and physical properties of the compound in order to inform the townspeople of any potential dangers. During the first week of lab, the group was given a small bottle containing an unknown white crystal-like substance. Their main goal of this week was to determine the identity of this unknown compound. The first step…

because salts are ionic compounds and molecules are covalent compounds. Justification: Salt is an ionic compound. An ionic compound is formed by ionic bonding between ions of opposite charge. Sodium Chloride and Potassium Bromide are both salts that have an ionic compound. Both elements have the properties of salts which include soluble in water, conductive, and a relatively high melting point. Molecules and Sugar molecules are covalent compounds. A covalent compound is made when two or more…

Have you ever thought about how fascinating it is that one familiar smell can bring back so many memories? The smell that can bring me back to my past and fill my heart with joy from the memories. The biggest memory that peppermint brings back for me is my Grandma. My Grandma was an amazing woman, she always wore a certain perfume and still to this day I am not entirely sure what the perfume was but it had some type of peppermint fragrance to it. My Grandmother and I used to do everything…

In this experiment one, are determining the melting points of different crystalline substances following a specific procedure. By finding the melting point of a crystalline substance, it helps determine what kind of compound it is as well as initiate the purity. A DigiMelt apparatus can be used to determine the melting point where a small amount of the the substance is packed into a capillary tube and heated slowly in the apparatus which includes a thermometer, a heating coil and a magnifying…

properties pave the way for future research in inhibitor technology. Introduction The inherent protection of metals and their alloys used in industry are of the upmost importance when it comes to longevity and reliability of structures. Many chemical compounds have been developed over the years that can inhibit the corrosion rate of metal alloys but cost effectiveness, toxicity, processibility and other factors limit the applications1. The need for new, eco-friendly and cost effective corrosion…

release fewer lights per unit area than inorganic solid-state based LED point-light sources. Introduction-An OLED (organic light-emitting diode) is a sort of LED (light-emitting diode), where the emissive electroluminescent level is a film of organic compound which releases light in response to an electric current. This layer of organic semiconductor material…

Introduction (succinctly) The mass media embodies a distinct symbolic system of expression for delivering messages to audience. Semiotic analyses on advertisement expose cultural norms and values associated with a particular society or group of people. The semiotic concepts of the icon, index and symbol must be carefully considered when analysing the media. “Semiotics highlights the way that we ourselves take part in the creation of meaning in messages, suggesting that we are not mere bystanders…
