Which of these equations are balance a) 3 h2so + 2ai = ai2(so4)3 3h2 b) 2kci + pb(no3)2 = 2kno3 + pbci2

Both equations are balanced.

a) 3H₂SO₄ + 2Al ⟶ Al₂(SO₄)₃ + 3H₂

On the left On the right

      6H                6H

      3S                 3S

    12O               12O

     2Al                2Al

b) 2KCl + Pb(NO₃)₂ ⟶ 2KNO₃ + PbCl₂

On the left   On the right

      2K                 2K

      2Cl               2Cl

      1Pb                1Pb

     2N                 2N

     6O                 6O

the millers tale is the answer.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
