When a solute is completely dissolved in a solvent, a solution is formed.
Each proton serves as a positive charge and each electron serves as a negative charge. The two charges neutralize each other on a 1:1 ratio. In your question, you have 12 protons to 13 electrons. That means there's a net -1 charge because there is one more electron than protons.
Answer:
The temperature would be too cold
Explanation:
f = 40 Hertz
Explanation:
Velocity of a wave = frequency × wavelength
frequency = velocity/wavelength
20m/s = f × 0.50
20/0.50 = f
40 Hertz = f or f = 40 Hertz
