Question

What is the name of the compound CrPO4 • 5H2O?

Answer 1

That would be

Chromium Phosphate pentahydrate

Answer 2

I think they use different prefixs in inorganic chemistry than organic, in inorganic it goes

1, 2, 3, 4, 5 ,6, 7 ,8, 9, 10
mono, di, tri, tetra, penta, hexa, hepta, octa, nano, deca

Answer 3

as for the PO4, it is best just to memorize the polyatomic ions, if you desire a career in chemistry it can be very helpful

Answer 4

usually though it goes

3 for ite
4 for ate

there is a chart I think but I dont know it has been 4 years since I have had to know this stuff, most of it is automatic for me now

Answer 6

why would you have to do addition?

Answer 7

molz

Answer 8

it is just asking for you to name the compound

Answer 9

1 mol Cr+ 1mol P + 4 MOL O

Answer 10

I have no idea what you are doing or what you are asking. the name of the compound is Chromium Phosphate pentahydrate

if you have any other question please state it clearly

Answer 11

PO4 (phosphate) is a polyatomic ion, just treat it as if it is one element, another example of a polyatmoic ion is nitrite (NO3) or nitrate (NO4)

Answer 12

I would check your chemistry text book for a list of polyatomic ions and memorize them it can be helpful when naming inorganic molecules

Answer 13

do you understand?
