Which of the following chemical equations violates the law of conservation of mass?
a. ti + 2cl2 yields ticl4
b. 2c2h2 + 5o2 yields 4co2 + 2h2o
c. li2so4 + 2ca(no3)2 yields 2lino3 + 2caso4
d, mgso4 + 2naoh yields mg(oh)2 + na2so4

8 moles of C

Explanation:

From the question given above, the following equation was obtained:

3A + 2B —> 6C

From the equation above,

3 moles of A reacted to produce 6 moles of C.

Thus, the number of mole of C produced by reacting 4 moles of A can be obtained as follow:

From the equation above,

3 moles of A reacted to produce 6 moles of C.

Therefore, 4 moles of C will react to produce = (4 × 6)/3 = 8 moles of C

Thus, 8 moles of C can be obtained from the reaction of 4 moles of A with excess B
