Question

Which of the following chemical equations violates the Law of Conservation of Mass?NaCl + KBr-NaBr + KCIHCI + KOH-H,0 + ACI2 H2 + O2-2 H202 H2 + N2 - 2 NH3

Answer 1

The Law of Conservation of Mass, basically states that in a reaction everything that undergoes the reaction must come out as product, no element will be lost or created, it does not matter the amount, the same amount of the element must be found on both sides, this is also the principle to balance equations.

According to this explanation, the best answer for this question will be letter D, where we have 2 H2 + N2 -> 2 NH3, you can notice that we have more Hydrogens (6), on the products side than on the reacting side (only 4). The correct and properly balanced equation for the production of Ammonia will be:

3 H2 + N2 -> 2 NH3

Let's analyze each option:

A) NaCl + KBr
