Questions 32 to 35 . select the number or formula which will balance the equation

32) A. 1

33) E. 2

34) C. 12

35) D. Sb₄O₆

Explanation:

32. N₂O₅ + __H₂O → 2HNO₃

left side: 2 H , 2 N, 6 O

right side: 2 H, 2 N, 6 O

Nothing needs to change, so put a 1

33. P₂O₅ + 3H₂O → __H₃PO₄

left side: 6 H, 2 P, 8 O

right side: 3 H, 1 P, 4 O

everything on the right needs to double, so put a 2

34. Sb₄O₆ + __HCl → 4SbCl₃ + 6H₂O

left side: 4 Sb, 6 O, 1 H, 1 Cl

right side: 4 Sb, 6 O, 12 H, 12 Cl

the H and Cl on the left both need to be multiplied by 12, so put a 12

35. + 4NaOH → 4NaSbO₂ + 2H₂O

left side: 4 Na, 4 O, 4 H

right side: 4 Na, 10 O, 4 H, 4 Sb

the left side needs 6 more O and 4 Sb, so add Sb₄O₆
