Ca(OH)₂ = Ca²⁺ + 2OH⁻
[OH⁻]=2c{Ca(OH)₂}
pH=14+lg[OH⁻]
pH=14+lg(2c{Ca(OH)₂})
pH=14+lg(2*0.0075)=12.18
Answer:
selective breeding
Explanation:
Example: pretend that rabbits can only be brown or black and black is dominant. If only the brown rabbits reproduce it will eventually be more common Hope this helps
I believe the correct answer from the choices listed above is the first option. During a physical change, m<span>olecules can move more rapidly and freely and change states.
