Question

1. please give the equation of above attachment ..

2. when we mixed the solutions of pottasium iodide in lead nitrate then what happens:
i.What was the colour of the precipitate formed? Can you name the compound precipitation ❓
ii. Write the balanced chemical equation for this reaction.
.
please Give the answer of both question..
chapter - chemical reaction and it's equation..​

Answer 1

Answer:

1. Bottom of test tube will feel cold. During the reaction, heat is absorbed. The reaction is endothermic.

Ba(OH)2 + NH4CL + heat -> BaCl2 + 2NH3 + 2H20

2. The reaction between lead nitrate and potassium iodide is an example of a precipitation reaction.

Lead nitrate reacts with Potassium iodide to form Lead iodide and Potassium nitrate.

Pb(NO3)2 + 2KI + PbI2 + 2KNO3

the precipitate formed is yellow in colour

Answer 2

Answer:

sorry dear I don't know the answer

btw

good night
