Calcium carbonate

In this lab, we tested different experiments on a candle flame in order to better understand properties, combustion, and states of matter. We recorded many observations that could help us reach a conclusion using what we saw happen. When we observed the regular candle flame, we concluded that the heat of the flame vaporizes the liquid wax. Then, we blew this candle out and took a different lit candle into the smoke trail from the burnt out candle. The wax vapor in the smoke is combustible,…

property. Groups or columns share similar electronic configurations, on which a variety of properties are based1. In the lab, the tested elements include those from Group 1, Group 2, Period 3, Period 4, Period 5, Period 6, and a series of metals (Calcium, Copper, Iron, Magnesium, Tin, Zinc). Group 1 elements have one valence electron and are extremely reactive. Most of the time, compounds containing Alkali metals are soluble in water. Alkaline earth metals, found in Group 2, have two valence…

Almost everybody has been told soda is bad for your teeth. To test this, chalk sticks of equal weight were put in six different types of soda. They were then compared to the chalk stick in the water. The results were that the Diet Mt. Dew is worse for teeth. After six days, the chalk still looked the same, but weighed one gram less. The chalk in the Coke was speckled with brown spots. In conclusion, the Diet Mt. Dew is concluded to be the worst soda for teeth, but the chalk didn’t change enough…

Almost all calcium is stored in bones and teeth, where it supports their structure and hardness (6). The body also needs calcium for muscles to move and for nerves to carry messages between the brain and every body part (6). In addition, calcium is used to help blood vessels move blood throughout the body and to help release hormones and enzymes that affect almost every function in the human body (6). Milk, yogurt, and cheese are the main food sources of calcium for the majority of people…

almost all organs where it influences the steadiness of calcium levels, neutralizes acidic and basic ions in a solution and has a role in…

Uranus: Uranus was discovered in 1781 by a British Astronomer named William Herschel, using a 6 inch telescope. At first he thought that it might be a nebulous star or even a comet, but after continued observation, he realized that it appeared to be a disk in the sky that moved relative to the stars. The movement was far too slow to be a comet and soon enough he realized that he had discovered the 7th planet at the time. At first, he wanted to name it Georgium Sidus which translates to…

Have you ever wondered, why teeth can change in color? The foods you eat and the liquids you drink affect the surface of your teeth. They can cause those pearly whites to either decay or stain. Knowing this we asked ourselves, what do different liquids do to your teeth? TEETH Chomp, chomp, chomp! For a very long time many of us have been wondering, what are teeth and what are they made of? Are they bones? We have your answer. They are a calcified tissue called dentin and other…

of excess carbon dioxide in the atmosphere. When carbon dioxide dissolves into sea water the pH levels of the water become much lower, therefore, making the water more acidic. Subsequently, this reaction diminishes the calcium carbonate minerals making them less abundant. Carbonate ions are the building blocks for the shells and skeletons of many marine organisms such as corals, mussels, and oysters. The average ocean pH is about 8.1 this level has already fallen from the beginning of the…

Excess Reagent 4. Stomach acid is made up of hydrochloric acid (HCl). How many percent by mass does hydrogen take up in the compound? A. 27% C. 1.6% B. 2.8% D. 2.0% 5. A piece of marble contains 8.74 x 1025 formula units of calcium carbonate (CaCO3). How many moles does it contain?…

From surfing, swimming, fishing, scuba diving, and going on boat rides on the beach most of us don’t really know what’s going on in our oceans. In reality besides the waste that goes in there’s actually acidification in our waters. Acidification is when the ocean uptakes carbon dioxide from the atmosphere, this also means the pH levels are lowering. The ocean acidification is negatively taking over our environment and there are barely any benefits that come with it. This essay will provide…
