Question

Which equation violates the Law of Conservation of Matter?

O A. 2 H₂SO3 + 4 H₂Se --> Sе6 + 6 H₂O
B. Al2(SO4)3 + 3 Ca(MnO4)2 → 2 Al(MnO4)3 + 3 CaSO4
5 HI 2 HIO3 --> 3 12 + 3 H₂O

Answer 1

The equation that violates the Law of Conservation of Matter is 5 HI + 2 HIO3 --> 3 12 + 3 H₂O

Step-by-step explanation:

This equation shows the formation of three molecules of iodine (I2) from two molecules of hydrogen iodate (HIO3) and five molecules of hydrogen iodide (HI), but it does not account for the atoms of iodine that are used to form the three molecules of iodine. According to the Law of Conservation of Matter, the total number of atoms of each element must be the same on both sides of a chemical equation, but in this equation, there are more atoms of iodine on the left-hand side than on the right-hand side. This means that the equation is not balanced, and it violates the Law of Conservation of Matter. The other equations listed are balanced and do not violate this law.
