Question

Plz do 29ques for me!!!!!!fast plz

Answer 1

Answer:

29).

a) first of all, we have to write the equation that we want here :

BaCl² + Na²SO⁴ ======= BaSO⁴ +NaCl

so this is the reaction but we have to balance it now;

for balancing the equation we do like this ...

Ba. 1. 1

Na. 2. 1

Cl. 2. 1

SO⁴ 1. 1

so now all the elements r balanced except Na and Cl ....lets balance it now-

BaCl² +NaSO⁴ ======== BaSO⁴ + 2NaCl

you can check it, this equation has been balanced .

b) the other name that can be given to this precipitation reaction is - 'double displacement reaction'. because here two elements are displacing each other ..u can see it in the equation.

{i hope this answer helped u and if it did then dont forget to mark it as a brainliest one , thanks :). }
