Calcium hydroxide

sulfuric acid D. 50 mL of 8 M sulfuric acid 5. Why does the rate of reaction increase when powdered calcium carbonate is used instead of marble chips? A. The powdered calcium carbonate acts as a catalyst. B. There is an increase of the particle size of the calcium carbonate. C. There is an increase of the surface area of the calcium carbonate. D. There is an increase of the concentration of the calcium carbonate. 6. Which of the following reactions will start with the highest rate? A. 5 g of…

My comprehensive treatment plan for Rangi will include restorative treatments, along with a caries management plan to avoid secondary caries and enhance enamel remineralisation. Furthermore, adequate preventive periodontal measures may halt the progression of Rangi’s gingivitis. I will plan Rangi’s treatment according to his caries risk status. According to the protocols for the clinical management of caries by risk factor level (CAMBRA), this is a positive measure of successful caries…

at So Curly, So Kinky, So Straight, will determine whether you’re a good candidate for either a Lye relaxer or No-lye treatment. A Lye treatment is generally a faster process, but may not last quite as long. Meanwhile, a No-lye treatment uses calcium hydroxide, which is known to be drying but…

production, product manufacture, product use and waste management (Sun et al., 2017). Lithium is extracted from two sources - ore and salt brines - and the lithium minerals are then transformed into basic chemicals such as lithium carbonate, lithium hydroxide, and lithium chloride to produce many derivatives (Sun et al., 2017, p. 51-52; Wanger, 2010; USGS, 2018). Originally, the majority of lithium was produced from mineral ore sources - spodumene, lepidolite…

that can subdue alkalis, can dissolve specific metals and can turn them into salt, such as calcium, turns red on blue litmus paper, is corrosive or sour-tasting when it comes to liquid, generates pain in wounds, and turns colorless when placed in phenolphthalein which is used as a basic to acid indicator ("Definition of acid in English:"). Alkalis is any kind of substance that can produce OH ions, hydroxide ions, in water, which can also be known as 'basic', or 'basicity' ("GCSE CHEMISTRY - What…

tested and had a pH of 5. This means that the compound is acidic according to the pH scale. Being acidic means that the substance has more hydrogen ions than hydroxide ions according to “pH”3 .The chemical and physical properties are stated in Table 1. The compound was soluble in water and hydrochloric acid, but was not soluble in sodium hydroxide, toluene, and acetone as indicated by Table 2. For a compound to be soluble it means that the compound must be able to dissolve in a certain liquid.…

Increased ocean acidification isn’t the only thing affecting the ocean, but it is very problematic because it erodes aragonite which is a mineral of calcium carbonate. In other words it kills corals and causes the hard exoskeleton to erode. Action needs to be taken to ensure the survival of corals and the creatures that rely on coral reefs to survive. Coral reefs are sources of food for millions of people, but also are sources of medicines. As coral reefs disappear so do the organisms that are…

Factory farming is a cruel, unsanitary, and abusive practice that has many harmful affects not only the animals confined in slaughterhouses, but also on unsuspecting consumers. By creating tighter government regulations regarding how the animals are raised and how the meat is treated, we could avoid all of the potentially deadly side effects linked to factory farming. While mass production of poultry and beef has done wonders for restaurant supply and company profit, the measures taken to…

added to water (H2O), hypochlorous acid (HOCl) and/or hypochlorite anions (OCl-) are formed. The combination of these creates free chlorine, the most effective chlorine based disinfectant. Common chlorinating products include chlorine gas (Cl2) and calcium hypochlorite [Ca(OCl)2]. The water treatment process often consists of screening, coagulation, settling, filtering, and disinfection (How is Water Purified?, n.d.); refer to Figure 1. Figure 1: Water…
