(NEED HELP ASAP) Three treatments of different starting materials are listed.
Substance Characteristics
1
The substance was heated and then placed in an ice bath.
2
The substance was in a salt solution of 2M and later placed in a
solution of 4M to cause a reaction.
3
The substance was hammered and broken into pieces.
Which statement explains the treatments?
O Substance 1 was activated by a decrease in temperature, Substance 2 was activated by the change in
concentration, and Substance 3 decreased the surface area.
Substance 1 was activated by a decrease in temperature, Substance 2 was activated by the change in pressure,
and Substance 3 increased the surface area.
O Substance 1 was activated by the heat and inactivated by ice, Substance 2 was activated by the change in pressure,
and Substance 3 decreased the surface area.
O Substance 1 was activated by the heat and inactivated by ice, Substance 2 was activated by the change in
concentration, and Substance 3 increased the surface area.

Will give ! what are the advantages and disadvantages of nuclear power? check all that apply. one advantage of nuclear energy is that it does not produce carbon dioxide emissions. storage of nuclear waste is a short-term problem associated with nuclear energy. the problem with uranium mining is that a large quantity of uranium must be extracted to meet energy needs because the energy release from uranium fission is so low. safe operation of a nuclear power plant can be jeopardized by a human mistake.

A0.10 m aqueous solution of sodium sulfate is a better conductor of electricity than a 0.10 m aqueous solution of sodium chloride. which of the following best explains this observation? (a) sodium sulfate is more soluble in water than sodium chloride. (b) sodium sulfate has a higher molar mass than sodium chloride. (c) to prepare a given volume of 0.10 m solution, the mass of sodium sulfate needed is more than twice the mass of sodium chloride needed. (d) more moles of ions are present in a given volume of 0.10 m sodium sulfate than in the same volume of 0.10 m sodium chloride. (e) the degree of dissociation of sodium sulfate in solution is significantly greater than that of sodium chloride.
