need a lil bit of chemistry help...?

Question

The active ingredient in many laundry bleaches is

When hydrogen burns in chlorine, the product is

Hydrogen chloride is made in the laboratory by the action of sodium chloride on

Chlorine may be obtained from hydrochloric acid by

mind you all you mean posters that like to tell ppl to do there own homework there where 100 questions on this thing and these are the only ones i dont know

Answer 1

1. sodium hypochlorite
2. hydrogen chloride
3. concentrated sulphuric acid
4. oxidising it, for example with potassium manganate(VII).

If you've done the other 96, well done!

Answer 2

Question 1.
sodium hypochlorite (NaClO)
At least, that's what they used to use when I was at secondary school (50 years ago). Maybe they've found something better in the meantime.

Question 2.
hydrogen chloride: H2(g) + Cl2(g) ---> 2 HCl(g)

Question 3.
One can use any strong, non-volatile acid. The most obvious choice is sulphuric acid.
H2SO4(l) + NaCl(s) ---> HCl(g) + NaHSO4
or H2SO4(l) + 2 NaCl(s) ---> 2 HCl(g) + Na2SO4

Question 4.
Electrolysis is the simplest way. The equation is the exact opposite of the one in question 2:
2 HCl(aq) ---> Cl2(g) + H2(g)

Answer 3

bleach is hypochlourus acid HClO
H2+Cl2--->2HCL hydrochloric acid
NaCl + ----->HCl (somethng with H in it, ?)HF will replace the Cl in NaCl leaving H and Cl, which probably would combine
HCl can be split be electrolysis to get Cl2
