Did you ever wonder what happens to your teeth when you drink sugary drinks? If you didn’t know already, drinks like soda, coffee, sports drinks, etc.. are known to be bad for your teeth. But what is in these drinks that cause damage to your teeth? Your mouth feed on sugar, and when they do, they also make acids. Too much acid in your mouth can eventually damage the enamel on your teeth, leaving your teeth vulnerable to tooth decay and cavities. Therefore, acid from soda and produced…

the stomach acid can aggravate and cause inflammation to the stomach; this leads to indigestion or heartburn. Antacids are medicines that can relieve symptoms of indigestion by neutralising the acid in the stomach. They are made up of bases and carbonates and can be taken as a liquid or a tablet. Another way to minimise the risk…

observation. Third, sulfate, place one milliliter sodium sulfate into a test tube, add one ml hydrochloric acid, and add 3-4 drops of barium chloride. Warm it in a water and cool it for serval minutes. Record your observation. Lastly, carbonate, place a small portion of sodium carbonate into a test tube and place it in a rack. Add 3-4 drops of hydrochloric acid to cover the solid. Stand and observe and record it on the data…

consists of Gastropod Limestone, Upper Clastic, Middle Limestone and Lower Clastic. Gastropod limestone is typically dark gray or white when exposed, and the new rocks are in either gray color or sparkly crystals, indicating the calcium carbonate. The grains of the carbonate stones vary from fine to sand-sized. This member of the Kootenai formation preserves fossils such as gastropods that date back to the late Cretaceous period. Gastropod Fossil is from the mollusk class, and it leaves spirally…

Lead, with its chemical symbol Pb, is a common heavy metal often utilized in many things. The chemical itself is toxic, heavy, and poisonous. Its natural form is a soft and malleable metal with blue-gray color. Lead can be man-made or found in nature, most can be obtained from ores. Even though lead is such a common metal on this planet, it only makes up 0.0013% of the Earth’s crust. Lead is easily mined or made by roasting galena in hot air, which is mostly made of lead sulfate. Lead was…

(phenolphthalein – an acid-base indicator)? (1) - How does compound X react with C20H14O4 (phenolphthalein)? (2) - How does compound X react with water? (3) - How does compound X react with hydro chloric acid (HCL)? (4) 3. Predictions. - Compound X is calcium carbonate (CaCO3). - (1) When compound X is heated and reacted with C20H14O4, the substance will turn pink. - If a red litmus paper is dipped in the substance moistened with de-ionized water, it will turn blue. - (2) When C20H14O4 is…

experiment, nitric acid HNO3 is combined with sodium carbonate Na2CO3. This mixture also remains clear and no visible reaction is present in the test tube. After the reaction, no visible reaction and non-reactivity is present in the test tube just like the way it started. The activity of metals for this reaction is that sodium has a higher reactivity than hydrogen, being able to replace hydrogen in the compound5. In this reaction, nitric acid and sodium carbonate reacts to produce sodium nitrate…

Zinc is the member of the first row transition series of elements, consisting of Sc, Ti, Cr, Mn, Co, Ni, Cu, Zn, Cd and Hg. All these elements belong to group 12 of periodic table. Zinc has an atomic number 30, an atomic mass of 65 and one main oxidation state (+2). Zinc has five nature isotopes . Zinc is the 24th most abundant element in the earth’s crust. Its properties is very similar to Cd.Zinc is very useful in biological systems. Zinc also is involved in many biochemical processes that…

and hydrogen ions, the amount of carbonate ions which are necessary in the creation of coral shells and skeletons decrease significantly. (Australian Government, n.d.) Therefore, more acidic seawater impacts coral significantly, dissolving their shells and skeletons, and hindering their ability to absorb calcium carbonate. Ocean acidification not only impacts coral and the animals that rely on coral as their main food source, but the animals that make calcium carbonate shells such as snails and…
