    1. What is the difference between calcium carbonate and hydroxyapatite? Calcium carbonate is more soluble than hydroxyapatite. 2. What are the pitfalls of using CHA in bone graft procedures? CHA is fragile an brittle and it should only be used temporarily 3. What is CHACC and what potentially makes it better than CHA? CHACC is Coralline Hydroxyapatite/calcium carbonate. CHACC is better than CHA because it can keep a porous structure as well s biocompatibility making it a even better player for bone grafts. There are improved biodegradation proprieties that can be suitable for bone remodeling to support natural bone healing process. 4. What is being shown in figure 1? Figure 1 shows the surface structure of CHACC using a Scanning electron micrographs at different levels of…

    Gravimetric Analysis of a Metal Carbonate Purpose The purpose of this lab is to find the mass of an unknown metal by conducting a double-displacement precipitation reaction, which is our gravimetric analysis. Once we find the precipitate mass, we can then find the molar mass by using the molar ratio given in the reaction equation. Procedure First, we set up the ring stand with a Bunsen burner, put a crucible on top of the pipe stem triangle and heated the crucible for a minute, then let it…

    1. Synopsis The main aim of the experiment is to find out the percentage of calcium carbonate in toothpaste by using back titration since calcium carbonate is an insoluble salt and does not dissolve in water. Back titration is a reverse method of titration used to obtain unknown concentration of analyte. A roughly weighed quantity of toothpaste? calcium carbonate is dissolved in a known amount of hydrochloric acid and is then titrated against sodium hydroxide. An orange colour will be observed…

    materials encompass mineralized biological tissues. They often are weak on their own, but do interact with organic matrixes to produce sufficient, structural materials. They have organized layers of organic and inorganic structures. They also may contain porous and fibrous elements. Biological organisms produce composites that are organized based on their composition and structure, containing both organic and inorganic components. Hard biological materials - composites of an inorganic oxide…

    As it can be seen in the previous figure, the Bubble Column PBR is a simple conceptual design. The figure simply illustrates the basic flow in the column. The gas enters the bottom of the column through a diffuser causing the gas to break into thousands of small bubbles making it easier for the algae to absorb the carbon dioxide in the gas. Once the algae have consumed as much carbon dioxide as it can, it releases oxygen in the form of gas, which leaves the column through the opening in the…

    Essay On Egg Osmosis

    • 4 Pages

    why? We did this experiment to learn about osmosis, and how that works in our own cells. Before we put the egg into any liquids, we took observations about the egg. If we had not put the egg in the liquids, the eggs would have started to decompose and smell bad. The same thing happens when you die, when your cells are dying, and your body isn't there to recycle the parts of the cell, you start to decompose and smell. The first liquid the egg was put into was vinegar. When the egg was put…

    Water Hardness Essay

    • 733 Words
    • 3 Pages

    Introduction The definition of water hardness, in its simplest form, can be explained as, “the amount of dissolved calcium and magnesium in water.” Water hardness can be attributed to groundwater systems naturally flowing through soil and rock. While doing so, divalent amounts of cations from mineral sources dissolve into the water supply (USGS). Water hardness is not harmful to people’s health. In fact, these minerals can be beneficial, as humans need minerals to survive. However, water…

    are a great deal of effects increased CO2 concentrations will have on this planet. When the ocean absorbs CO2 chemical reactions occur that eventually reduces their pH, carbonate ion concentration, and saturation states of important calcium carbonate minerals. This is known as ocean acidification and with the altering of saturation states coral reefs around the world have suffered a great impact because of this. The ocean is one of the largest natural reservoirs and absorbs one third of the…

    also used in research of other possible fuels by finding the cost to produce it and comparing it to the amount of energy it will provide to find out if it is a worthwhile investment. The main objectives of this lab are to find the energy changes in reactions two and three then using two and three find the ideal reaction one’s change in energy. The general experimental design is that using a calorimeter you would first find the change in energy of calcium carbonate reacting with two hydrochloric…

    Determining the Percentage Yield of a Chemical Reaction Question: What is the percentage yield of the reaction of sodium carbonate and calcium chloride dihydrate (the dihydrate must be included with the molar mass calculation)? Predictions: Predict the mass of sodium carbonate and calcium chloride dihydrate that will be required to produce 1.90 grams of calcium carbonate: Therefore, the predicted mass of sodium carbonate is 2.0 grams and the predicted mass of…
