Question

balance the equation; bacl2 + h2so4 +baso4 hcl

Answer 1

Hi there!

Query,
Balance: $BaCl_2$ + $H_2SO_4$ → $BaSO_4$ + $HCl$

ANSWER:

$BaCl_2$ + $H_2SO_4$ → $BaSO_4$ + $2HCl$

Cheers!

Answer 2

In the given reaction,  

$\mathrm{BaCl}_{2}+\mathrm{H}_{2} \mathrm{SO}_{4} \rightarrow \mathrm{BaSO}_{4}+\mathrm{HCl}$

Here check the elements at both sides:

1 Ba atom  = 1 Ba atom = Balance  

2 Cl atoms =  Must be 2 Cl atoms = not balance

2 H atoms =  Must be 2 Cl atoms = not balance

$1\ \mathrm{SO}_{4} \text { ion }=1\ \mathrm{SO}_{4}= \text { balance }$

Hence the balance equation must be:  

$\mathrm{BaCl}_{2}+\mathrm{H}_{2} \mathrm{SO}_{4} \rightarrow \mathrm{BaSO}_{4}+2 \mathrm{HCl}$
