Actualy as of ast night the compound NH4CI is indeed the wrong name and is more correctly named the NH3CI. It is not formed by any elements. !Caper!
Three elements viz. Nitrgoen (N) , Hydrohen(H) and Chlorine(Cl).
NB . When writing up chemical formula; -
#1 ; Single letter symbols are ALWAYS a CAPITAL letter.
#2 ; A two letter symbol is written; dirst letter is a capital letter and the second letter is small/lower case.
This is the international recognised standard.
So for 'nh4cl'' it shoulkd be written as NH4Cl. not nh4cl.
Nitrogen is not a compound, it is an element. Nitrogen is found in many compounds, including all proteins.
Blood is a mixture of many substances.
This is just simple maths. If you need 2 grams of X for every 4 grams of Y, you need to multiply this up to the scale you are given 2x = 4y 4x = 8y 6x = 12y So you would need 6 grams of element X to make the same compound.
Neither; rice is a mixture of many compounds.
I'm not sure if it is a compound, but it is a diatomic element, which means its atoms cannot be distributed evenly and it exists only in pairsNo it is a diatomic molecule of the element Oxygen,
Nitrogen is not a compound, it is an element. Nitrogen is found in many compounds, including all proteins.
1 sodium, 1 phosphate
a subscript found at the bottom right of the letters in the compound. if there is no number, that indicates there is only one of that element, or atom.
The element known as cobalt is present in many compounds.
You are doubling the amount of D, so 8*2 = 16 grams of D required.
It varies with the compound.
a compound is made up of a number of different elements. many times carrying some of the characteristics of that element into that compound
One Copper is an element itself - not a compound
2 or more
The charge on individual ions when they form compounds is decreased or increased depending on if the ion needed or had too many electrons. I think....think that is the answer, so, get back to your textbook :)
Depends on the compound; chlorine can form an ionic bond with many elements. eg, NaCl, MgCl2, CsCl.
Mg which stands for Magnesium is the element to begin with, not a compound.
