Why is calcium carbonate useful? Calcium carbonate is a dietary supplement used when the amount of calcium taken in the diet is not enough. Calcium is needed by the body for healthy bones, muscles, nervous system, and heart. Calcium carbonate also is used as an antacid to relieve heartburn, acid indigestion, and upset stomach.
Why is calcium carbonate good for the environment? Ground calcium carbonate is a mildly alkaline product and is used in a variety of environmental applications. It is the most common reagent used in flue-gas desulfurization applications, removing harmful SO2 emissions from coal and other fossil fuel exhausts.
Why is calcium carbonate a better choice? Calcium carbonate supplements tends to be the best value, because they contain the highest amount of elemental calcium (about 40% by weight). Because calcium carbonate requires stomach acid for absorption, it’s best to take this product with food.
What is dry hard cider? January 22, 2012. Hard cider is the fermented, alcoholic cider [in comparison to non-bubbly, non-alcoholic cider that is served warm or cold]. Dry just means a cider that’s not too sweet. Brands: Hornsby, Strongbow, Woodchuck. Generally found near the beer.

What is meant by the term carbon footprint answers?
A carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions. The average carbon footprint for a person in the United States is 16 tons, one of the highest rates in the world.
What is aluminum carbonate used for?
Aluminum carbonate is used to treat the symptoms of increased stomach acid in conditions such as heartburn, acid reflux, acid indigestion, sour stomach, and stomach ulcers. Aluminum carbonate is also used to treat, control, or manage high levels of phosphate in the body.
What is carbon fibre composite made of?
About 90% of the carbon fibers produced are made from polyacrylonitrile (PAN). The remaining 10% are made from rayon or petroleum pitch. All of these materials are organic polymers, characterized by long strings of molecules bound together by carbon atoms.
Is lemonade a carbonated beverage?
Lemonade is a fizzy drink, strongly carbonated. It comes in two varieties, white (which is actually colourless) and red.
What makes carbon for steel?
Carbon steel or plain-carbon steel, is a metal alloy. It is a combination of two elements, iron and carbon. Other elements are present in quantities too small to affect its properties. The only other elements allowed in plain-carbon steel are: manganese (1.65% max), silicon (0.60% max), and copper (0.60% max).
How does carbon dioxide enter and leave the atmosphere?
Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. … Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.
Is cupcake moscato carbonated?
Wines labeled Moscato d’Asti are made in a style known as frizzante, which means slightly fizzy. … Although the wines were similar, we preferred the body and flavor of the Cupcake Moscato d’Asti. Both wines have a 5.5 percent alcohol level and were quite sweet.
When does a tertiary carbon do sn1?
1. If the nucleophile is a weak base, tertiary haloalkanes react by either an SN1 or E1 mechanism, and the SN1 reaction is favored. 2. If the nucleophile is a strong base, tertiary haloalkanes react by either an SN1 or E2 mechanism, and the E2 reaction is favored.
When a tree dies what happens to the stored carbon?
Forests sequester or store carbon mainly in trees and soil. While they mainly pull carbon out of the atmosphere—making them a sink—they also release carbon dioxide. This occurs naturally, such as when a tree dies and is decomposed (thereby releasing carbon dioxide, methane, and other gases).
How much atp from a 20 carbon fatty acid?
A) About 1,200 ATP molecules are ultimately produced per 20-carbon fatty acid oxidized. B) One FADH2 and two NADH are produced for each acetyl-CoA.
How is carbon monoxide?
Carbon monoxide is a colorless, odorless, tasteless gas produced by burning gasoline, wood, propane, charcoal or other fuel. Improperly ventilated appliances and engines, particularly in a tightly sealed or enclosed space, may allow carbon monoxide to accumulate to dangerous levels.
Is a carbon monoxide detector necessary?
Every home with at least one fuel-burning appliance/heater, attached garage or fireplace should have a carbon monoxide alarm. … An alarm should be installed on every level of the home and in sleeping areas.
What is atmospheric carbon sources?
Some processes release more carbon dioxide into the atmosphere than they absorb. Any process that uses fossil fuels—such as burning coal to make electricity—releases a lot of carbon into the atmosphere. … These processes that release carbon into the atmosphere are known as carbon sources.
What is a chiral carbon atom give example?
An asymmetric carbon atom (chiral carbon) is a carbon atom that is attached to four different types of atoms or groups of atoms. … Molecules that cannot be superimposed on their own mirror image are said to be chiral like mirror image.
How many carbon atoms enter the citric acid cycle?
Two carbon atoms come into the citric acid cycle from each acetyl group, representing four out of the six carbons of one glucose molecule.
How to remove carbon dioxide from water?
The most economical way to remove free carbon dioxide in water is by utilizing a process called “Decarbonation” or sometimes referred to as “Degasification”. Utilizing the decarbonation process will remove CO2 levels to 99% or higher.
What is water carbon dioxide sugar oxygen?
Carbon dioxide + Water Glucose (sugar) + Oxygen CO2 + H2O C6H12O6 + 6O2 Cellular respiration or aerobic respiration is a series of chemical reactions which begin with the reactants of sugar in the presence of oxygen to produce carbon dioxide and water as waste products.
Is composting a carbon sink?
In WARM, the net greenhouse gas impact from composting all types of organics is negative, implying that composting is a carbon sink—that composting stores more carbon in the soil than it emits to the air.

Why is copper carbonate blue?
When copper is oxidized by a combination of air, humid and finely divided acid and salts in the air, then a so-called patina of copper is formed. This is a basic copper (II) carbonate/sulfate mix, which has a cyan color. The reason that the color changes is that a chemical compound of copper is formed.
