Balance the following chemical equations by filling in all blanks.(even if the coefficient is

Question

1) a) ______Bi2S3 + ______HI  ______BiI3 + ______H2S b) ______NaCl + ______Pb(NO3)2  ______NaNO3 + ______PbCl2 d) ______C3H8 + ______O2  ________ + ________

Answer 1

d) 1 C₃H₈ + 5 O₂ ==> 3 CO₂ + 4 H₂O

Answer 2

1a) 4Bi2S3 + 24Hl = 8Bil3 +12H2S

each side has 8Bi, 24l, 24H and 12S

4x2 =8 Bi

24=12x2 H

24-8x3 l

24=12x2 H

1b) 2NaCl + 1Pb(NO3)2 = 2Na(NO3) + 1PbCl2
