Answer: I believe it would be using group input to discuss and prepare preliminary designs
Explanation:
Answer:
Strongly acidic [or strongly basic] solution will have high conductivity.
Explanation:
Answer: D, splitting water into hydrogen and oxygen is a chemical change.
Answer: A supersaturated solution will not contain undissolved solute because the undissolved solute will be indicative of saturated solution.
Explanation:
A supersaturated solution is the one that consists of more than the maximum concentration of the solute in the solvent that is being dissolved at a given temperature. A saturated solution is the one in which the maximum concentration of solute has been dissolved in the solvent and no additional solute can be dissolved further.
According to the given statement, a solution with undissolved solute is a saturated solution rather a supersaturated solution.
C
Decreasing the wavelength increases the frequency of a wave and vice versa, as long as the energy of the wave remains constant.
Explanation:
The energy of a wave is given by the formula;
E= hf
Whereby;
E = energy
h = Plank’s constant
f = frequency
Remember that f can be also represented as;
¹/ λ
Whereby;
λ = wavelength
Wavelength and frequency are therefore inversely proportional.
Decreasing the wavelength increases the frequency of a wave and vice versa, as long as the energy of the wave remains constant.
