Prelab Questions: 1. Explain what means when we say a substance is magnetic
2. Discuss the relatiiship between electe and magnetic hels
3. What type of metals are known as tenromagnetie metais?
4. Open the lab Interactive and run a few trials changing the variables each time. Decide which
vanable you want to change in order to make a strong electromagnet and record here
This will be your independent variable

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.

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.
