True - Because a sound wave carries energy; to propagate energy, energy must be applied for the sound wave to carry energy.
The equation is not balance because the law of conservation of mass is not being followed.
<h3>Why the equation is not balanced?</h3>
The hydrogen and chlorine atoms have different numbers of atoms in the reactants and products which is not balance on both sides i.e. reactant and products.
So we can conclude that the equation is not balance because the law of conservation of mass is not being followed.

Answer:
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.
