question 20 of 24\nin these chemical equations, each of the letters j through m represents a different element. which equation is balanced?\na. jk + l₂m → jm + 2lk\nb. 2jk₃ + 3l₂m → 6lk + j₂m₃\nc. 2jk + 3l₂m → 3lk + j₂m₃\nd. 3j₂k + l₂m₃ → 3jm + l₂k₃
Answer
Explanation:
Step1: Analyze option A
On the left - hand side: 1 J, 1 K, 2 L, 1 M. On the right - hand side: 1 J, 1 M, 2 L, 2 K. The number of K atoms is not balanced.
Step2: Analyze option B
Left - hand side: 2 J, 6 K, 6 L, 3 M. Right - hand side: 2 J, 6 K, 6 L, 3 M. The number of each type of atom is the same on both sides.
Step3: Analyze option C
Left - hand side: 2 J, 2 K, 6 L, 3 M. Right - hand side: 2 J, 3 K, 3 L, 3 M. The number of K and L atoms is not balanced.
Step4: Analyze option D
Left - hand side: 6 J, 3 K, 2 L, 3 M. Right - hand side: 3 J, 3 M, 2 L, 3 K. The number of J atoms is not balanced.
Answer:
B. $2JK_{3}+3L_{2}M\rightarrow6LK + J_{2}M_{3}$
