How do differences in temperature effect air masses?
laiz [17]

Answer:

The difference in temperature causes differences in air pressure between the two spots. ... This causes the jet stream to dip farther south and the winds to blow stronger on either side of the jet stream in winter. The jet stream separates the very cold air mass at higher latitudes from the warmer air mass equatorward.

Based on the chemical formula and state of matter, which of these substances will conduct electricity?
Sergeu [11.5K]

Answer:

CuSO4(aq)

Explanation:

The aqueous form of copper sulfate will conduct electricity.

The Solid form will not be a good conductor.

C₅H₁₂ will not conduct electricity

CO₂ will not conduct electricity

  • Copper sulfate is an ionic compound
  • In aqueous solutions or molten forms, ionic compounds can conduct an electric current using free mobile ions as carriers.
  • This way, they are electrolytes.
  • In solid state, the ions are arranged into a crystal lattice and will not conduct a current of electricity.

Which of the following elements will form negative ions? Check<br> all that apply.
AleksandrR [38]

Answer:

Explanation:

Elements on the right side of the periodic table are very likely to form negative ions -- all of those except elements in the 8th or 18th column (depending on how your periodic table is numbered).

K and Mg are on the left side, so they will not form negative ions.

They give up 1 (for K) electron and 2 (for Mg) electrons which will leave plus charges for the ions.

On the other hand S and I are on the right side of the periodic table. They will take on electrons and hence be charged with a minus.
