Answer 1

Here is the Solution:

1 (q) Yes reachon occur potassitum nitrate (kno) and when aqucous soleution aquous potassium odide (KI) and obalt ) nitrate co(No3)2 formed ompound.Because obalt cobalt ) fodide are combfnaa which are reatant can consider Selid ompound SO, we 2odide prodect it as Ffrst, we wfu orfte tha balaned Chemical equation 2 KNO3 (an) Co2 (s) 2 KI (aa Co (NO32 (aa) Se ond we will orfte the complete oni equahon 2K ant 21an)Co an)t 2N03 2t Col262Kar)2 (aa) Now, cancel out the Spectator ions an both side of the Lomplet fomic equaton andwrite the remaining net onic eauaton Substante as 2 1) 21 e)t Co)2 DCOT2 (s) +2 (ar) Net fonfc equatfon 2+ Co 21 (an) DCOI2 (an)
