Red blood cells are cells that transport oxygen from the lungs to cells of the body and then transport carbon dioxide from the cells to the lungs. Without red blood cells, animal respiration as we know it would not exist. The critical part of the red blood cell is a protein called hemogl...
Argon Symbol: ArArgon Atomic Number: 18Argon Atomic Weight: 39.948What is Argon?Argon (Ar, atomic number 18) is the third most common gas in the world, even more so than carbon dioxide. The word "argon" means inactive, inert in Greek and refers to this gas in that it reacts with ...
The polymerized form of chloroethene or vinyl chloride is a matrix of double the bonded carbon molecule CH2=CHCl. The double bonds break and become single bonds, and the vinyl chloride molecules become bonded to each other. The result is PVC or polyvinyl chloride plastic. The burning of PVC...
Small amounts of beryllium were synthesised during the Big Bang, although most of it decayed or reacted further within stars to create larger nucleii, like carbon, nitrogen or oxygen. Beryllium is classified by the International Agency for Research on Cancer as Group 1 carcinogens.[9] Between ...
Diamonds heated to a high temperature in pure oxygen transform to carbon dioxide—they simply evaporate! So given enough heat and oxygen we too can transform, even the hardest heart. Diamonds have been used for millennia, 2500 BCE in China, 1500 BCE in India. The stone was often found on ...
Interestingly, nitrogen is used to pressure kegs for some types of beer such as British ales and stouts. Nitrogen-charged beers are packaged in bottles and cans with the use of a pressure-sensitive nitrogen capsule. A mixture of carbon dioxide and nitrogen is used to saturate beer with carbon...
Give the symbol for each element: (a) sulfur, (b) sodium, and (c) aluminum. Classify each substance (I have to write which are elements and which are compounds). calcium, carbon dioxide, chalk, mercury, graphene, salt, sodium, sugar, water, zinc. ...
