    Question. How can nitric oxide production from perfused organs be determined? Problem. It is thought that Nitric Oxide is important in signalling between neurons as well as in the vascular endothelium. NO plays a key role as the endothelium-derived relaxing factor (EDRF), which regulates vascular constriction and relaxation and is thus highly correlated with perfused organs (1). Since nitric oxide is so important in the vascular system, a sensitive and specific method is needed to detect it in

    Calorimetry 1 The purpose of this experiment is to identify the mystery metal given to us (metal A). We are going to identify the mystery metal by looking at both its physical properties as well as its heat capacity. The heat capacity of the metal will be calculated using a setup/method described below. We will also look at the physical properties of the metal such as its magnetic properties, density, whether it is lustrous or dull, etc. by observation. Our mystery metal is not very lustrous and

    Titanium Dioxide (TiO2) is known as the ultimate white pigment because of its high refractive index and also its brightness. This dust is naturally occurring from the oxides of titanium. This compound has many application uses. These include Paint manufacturing, food coloring, sunscreen products and the Pharmaceutical industry to name a few. According to the IARC (International Agency for Research on Cancer), it is classified as a Group 2B Carcinogen, basically it states that it is potentially cancerous

  • Molar Mass Lab Report

    Conclusion: Every compound has a uniquely identifying molar mass as well as individual properties. In this lab, the purpose was to use the properties that three unknown alkali metal carbonate powers have, to identify the molar mass. For the three unknown substances, they all were white powders of about the same texture, and they all reacted when added to hydrochloric acid. Based on these properties, it is impossible to distinguish which one is which due to the similarities, so it is necessary to

  • Determination Of The Chemical Formula Of Magnesium Oxide

    1325 Words  | 6 Pages

    This investigation is about proving the formula of magnesium oxide by making magnesium oxide. The first reactant of the experiment is magnesium metal (Mg) and oxygen (O2), the oxygen will be in the air and provide oxygen atoms for the formation of magnesium oxide (MgO), which is the product of this experiment (In association with Nuffield Foundation). We are performing this experiment to improve our critical thinking skills as we will have to analyse the data and results to form conclusions, and

    independently discovered oxygen, They were both able to produce oxygen by heating mercuric oxide (Hg0) . Oxygen is a highly reactive element and is capable of combining with other elements . It is required by most living organisms and for most forms of combustion . Oxygen and Magnesium combine in a chemical reaction to form this compound. When the magnesium metal burns it react with oxygen found in the air to form Magnesium Oxide. Mg loses the electrons to have an octet , Oxygen gains two electrons to have an

    started to use. I quickly paused the experiment once I noticed the rubber tongs were gluing together. This minor mistake is avoidable and easy to fix. Our first conclusion was that magnesium burns to form new compounds. It reacts with oxygen to form oxides of each metal. This was an example of combustion and combination/synthesis reactions. Next, was the CuCO3 reaction, where we used a wood splint to discover that CO2 gas was present. After we
