Question

the conservation of matter can be demonstrated by using chemical equations. which chemical equation demonstrates the conservation of matter?
o i₂ + 5cl₂ + 6h₂o → 2hio₃ + 10hcl
o 2sn + 4hno₃ → sno₂ + 4no₂ + h₂o
o 4p + 5hno₃ → 5no + 3h₃po₄
o cl + 4na → 4nacl

Explanation:

Step1: Count atoms in first equation

  • Left - hand side (LHS):
  • \(I\): \(2\) atoms (\(I_2\))
  • \(Cl\): \(5\times2 = 10\) atoms (\(5Cl_2\))
  • \(H\): \(6\times2=12\) atoms (\(6H_2O\))
  • \(O\): \(6\) atoms (\(6H_2O\))
  • Right - hand side (RHS):
  • \(I\): \(2\) atoms (\(2HIO_3\))
  • \(Cl\): \(10\) atoms (\(10HCl\))
  • \(H\): \(2 + 10=12\) atoms (\(2HIO_3+10HCl\))
  • \(O\): \(2\times3 = 6\) atoms (\(2HIO_3\))

Step2: Count atoms in second equation

  • LHS:
  • \(Sn\): \(2\) atoms (\(2Sn\))
  • \(H\): \(4\) atoms (\(4HNO_3\))
  • \(N\): \(4\) atoms (\(4HNO_3\))
  • \(O\): \(4\times3=12\) atoms (\(4HNO_3\))
  • RHS:
  • \(Sn\): \(1\) atom (\(SnO_2\))
  • \(H\): \(2\) atoms (\(H_2O\))
  • \(N\): \(4\) atoms (\(4NO_2\))
  • \(O\): \(2+(4\times2)+1=11\) atoms (\(SnO_2 + 4NO_2+H_2O\))

Step3: Count atoms in third equation

  • LHS:
  • \(P\): \(4\) atoms (\(4P\))
  • \(H\): \(5\) atoms (\(5HNO_3\))
  • \(N\): \(5\) atoms (\(5HNO_3\))
  • \(O\): \(5\times3 = 15\) atoms (\(5HNO_3\))
  • RHS:
  • \(P\): \(3\) atoms (\(3H_3PO_4\))
  • \(H\): \(3\times3=9\) atoms (\(3H_3PO_4\))
  • \(N\): \(5\) atoms (\(5NO\))
  • \(O\): \(5+(3\times4)=17\) atoms (\(5NO + 3H_3PO_4\))

Step4: Count atoms in fourth equation

  • LHS:
  • \(Cl\): \(2\) atoms (\(Cl_2\))
  • \(Na\): \(4\) atoms (\(4Na\))
  • RHS:
  • \(Cl\): \(4\) atoms (\(4NaCl\))
  • \(Na\): \(4\) atoms (\(4NaCl\))

Answer:

\(I_2 + 5Cl_2+6H_2O
ightarrow2HIO_3 + 10HCl\)
