Hello Newsgroup,
I have a child in independent studies and am trying to help him with
his science studies. Its been 30+ years since I did anything in
science and the book is greek to me. So any help with helping me to
understand the following would be greatly appreciated.
The chapter review is due on Tuesday Oct 17. Any help is appreciated.
Here are the questions and where possible my best guess
Using the equation below complete the statements below
Na + AgCl -> NaCl +Ag
A. This is a (single replacement/decompostion) reaction.
B. The mass of Na +AgCl must equal the mass of AG / NaCL + Ag). I
don't think this means division, but are the choices for the answer.
My Answer is NaCl + Ag (law of conservation of matter, I think)
C. One of hte reactants in this equation is (na/NaCl)
D. One product of this equation is (AgCl/NaCl)
I think it is AgCl as NaCl is one of the elements within the
equation.
E. This equation is (balanced/unbalanced)
Looks balanced to me, but not real sure. Don't know how to tell
if this is correct or not.
F. The nonmetal ion is this equation is (Ag+1 /CL-1)
The book my son is using is Globe Physical Science by Bryan Bunch and
Marie E. Marshall, Unit 5 review is what I am trying to assist with.
