The four most abundant elements in the human body – hydrogen, oxygen, carbon and nitrogen – account for more than 99 per cent of the atoms inside you. They are found throughout your body, mostly as water but also as components of biomolecules such as proteins, fats, DNA and carbohydrates...
Similarly, hydrogen and oxygen, which are both gaseous elements can combine to form water, which is a liquid compound, not a gas, at room temperature. The process by which such combinations and transformations of elements into compounds take place is called achemical reaction. ...
Hexachloroethane is a member of the class of chloroethanes, which is ethane, in which all the hydrogens are replaced by chloro groups. It is also called HCE, perchloroethane, and carbon hexachloride. It has a role as a carcinogenic agent and a refrigerant. Chemical property Hexachloroethan...
A 21.22 g sample of a compound contains 6.77 g potassium, 6.14 g chlorine, and oxygen. Calculate the empirical formula. What is the empirical formula of a compound that is 13.5% calcium, 10.8% oxygen, and 0.675% hydrogen by mass?
Hydrogen in its elemental form, H2, by definition has oxidation number 0. Most common oxidation state of hydrogen is +1, which is a... See full answer below.Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer ...
Oxygen Bleach: Not Your Mother’s Bleach! Traditional bleach is what we refer to as chlorine bleach. It uses sodium hypochlorite—a highly toxic substance—as an oxidizer to break chemical bonds and release stain-causing substances. Many of us grew up in homes where chlorine bleach was the st...
