Calcium

1. Calcium is the fifth common element in the earth’s crust, and is found predominantly in feldspar, calcite, dolomite, and apatite, as a primary and secondary mineral. Calcium is found in lime stone but is also added as lime and in fertilizers. However, Calcium is not added as the soil is insufficient in Calcium, but to increase the pH. Calcium is a macro-nutrient which is essential in plant growth, the functioning of root tips, and is a main constituent in the cell wall. The amount of Calcium…

literature Ksp for calcium hydroxide is 5.02×〖10〗^(-6), which is a relatively large Ksp value. This goes against the “rules of solubility” that labels calcium hydroxide as insoluble. According to the “rules of solubility”, calcium hydroxide should not be soluble in water; however, our results reveal that it does have some degree of solubility at standard conditions. We know this because we started with an initial concentration of calcium hydroxide and no concentration of either calcium or…

to the weakening of her bones. 2.) If Susan had bone cancer, the CT scan would reveal the presence of a tumor. The densitometry scan would also show a change in the density of the bone due to cancer. 3.) Vitamin D helps the bones to absorb more calcium. 4.) Susan has a nondisplaced oblique fracture of the neck of the femur. A nondisplaced oblique fracture is when the bone did not move from its original anatomical position, but fractured diagonally across the neck of the femur.…

was that unknown was calcium chloride. This conclusion came from a couple of sources of reasoning. First, a number of compounds were present in the lab, and one of those had to be the unknown. Second, the unknown was white and spherical in shape, and so these characteristics were examined for in the possible compounds. Compounds that were sand-like in texture or liquid in their present physical state were passed over since none of those compounds could be the unknown. Calcium chloride physically…

Number two seller is what? Calcium citrate… and calcium citrate is just calcium carbonate that's reacted with citric acid, so it’s also stone, and what’s the number three seller? Calcium citrate malate and that also is just chemically reacted rock. So you have the top three selling calcium ingredients are rock, rock, and rock. OK, that represents more than ninety percent of calcium supplements. I'm being conservative in saying ninety. Would you eat a lemon and limestone pie? Probably not right?…

Calcium hydroxide (Ca(OH)2), universally referred to as lime water or slaked lime is formed by reacting hydrated lime (calcium oxide, CaO) with water (H2O)[1] CaO (s) + H2O (l) ⇌ Ca(OH)2 (aq) (ΔHr = −63.7 kJ/mol of CaO) Calcium hydroxide is an economically favorable alkaline reagent to neutralize acid as it yields 2 moles of (OH)2 for every 1 mole of Ca(OH)2 (which is slightly soluble in water) when compared to sodium hydroxide [1] and it may separate from the solution ‘constant agitation must…

The Difference between Detergent and Soap The reason for this case study is to dissect the Difference between detergent and soap. In this case study, I will define the meaning of the cleaning agents, I will give you an introductory, I will discover how they are made, I will discover how they work, and why one cleaning agents is better than the other. This case study will be designed using the descriptive scientific method. The meanings of Detergent and Soap A detergent is a substance that cleans…

The Salter-Harris classification is a radiologic classification system, developed in the 1960s, to describe fractures involving the growth plate in pediatric patients.1 It divides the fractures into five categories based on the extent of damage to the growth plate based on the mnemonic SALTER; type I: Slip or Separation of the growth plate, type II: Above the growth plate, type III: Lower than the growth plate, type IV: Through the growth plate, and type V: Raised epiphysis. Children have open…

There are many different fractures, however, the main categories are incomplete, complete, simple, and compound. Fractures that are incomplete or complete, refer to the way the bone breaks. The incomplete fracture is when the bone cracks, but does not break all the way through. As with the complete fracture, the bone breaks in two or more parts. With the compound or simple fracture, this is referring to rather or not the bone broke through the skin. With a compound fracture, also known as an…

Introduction Determination of bone mineral density helps in assessing bone quality. For instance, loss of bone mass which is obtained clinically as the change in BDM (bone mineral density) aids in determining bone fragility (Paschalis, 2009). Though, bone mineral density cannot be used alone to indicate that someone will suffer from bone fracture since there is the difference in BDM between the populations. Some people in a particular community develop bone fracture while others do not. Some…
