How do you determine the chemical symbol for an compound or molecules from looking at its name?

Question

And, is H2S hydrogen sulfide?

Answer 1

I think that you wanted to ask a different question. The question that you wanted to ask was, "How do you determine the chemical formula for a compound or a molecule from looking at it's name?"

For example, you looked at the name "hydrogen sulfide," and you wondered if that could be H2S. Yes, it is.

I am afraid that I cannot give you a better answer than others have done. You must learn the names of chemical compounds that your teacher tells you that you need to know, and then youi must memorize their formulas. The formulas are composed of the chemical symbols of the elements.

I'm sorry that I cannot help you further. Your only reward for hard work is to be asked to work harder. Love from Steve .

Answer 2

There is no rule for determining chemical symbols from names. You have to memorize them.

H2S is hydrogen sulfide.

Answer 3

you cant you have to learn the periodic table and the rules for the chemical attraction. sorry. but yes H2S is hydrogen sulfide.

Answer 4

Ionic compounds are shaped between a steel and non-steel aspects on the periodic table. They make an ionic bonds. Molecular compounds are shaped between 2 or extra non-steel aspects. They make covalent bonds. Ionic bonds cope with the circulate of electrons. One element (frequently the steel) donates or supplies a definite sort of electrons to the the different element (the non-steel). some examples: NaCl, Ca3P2, K3N Covalent bonds deals with the sharing of electrons. fairly of thoroughly freely giving electrons, 2 non-metals will proportion them. some examples are: O2, C3P4, etc yet another ingredient to observe: Ionic bonds - subscripts would properly be predicted for each compound (utilising the periodic table). Covalent bonds - the subscripts can't be predicted.
