can someone plz ans these questions

26) C- remember that you have to remove one of the parts of the fire triangle (heat, fuel, oxygen)
22) C- sodium hydroxide gives white pt with Zn, silver nitrate gives white ppt with chlorides.
23) A- the concentration of the acid decreases.
17) A. (I just remember the answer, you didn't give the substances in bold)

i think:
26- C, coz water takes in d heat, n cools d fire
22-C, NaOH coz of zinc ion, it gives white ppt, n silver nitrate coz of Cl ion, it gives white ppt(remembr halogens n all)
23-A, spd decreases coz u make d solun of HCl dilute, so lesser particles 2 collide wid, so slower rate of rxn
17--bro, uve not made it bold, ne way, ans is A, k my guess
all this is what i think i may well b wrong
