Use the table to answer the following question. Properties of Elements
Element 1
• shiny
• malleable
• conductive
Element 2
• gas
. non-conductive
When these elements react to form a compound, what would you predict the properties to be?
A The compound will probably have properties of both elements like a metalloid.
B. The compound will probably have high boiling points and melting points and will be conductive in solution.
C. The compound will probably have high boiling and melting points and will not be conducive in solution.
D. The compound will probably have low boiling and melting points and will not be conducive in solution.

Under what conditions will a gas be most likely to exhibit the ideal gas properties predicted by the ideal gas law? 1)high pressures and high temperature, because particles are forced closer together with higher kinetic energy, so intermolecular forces of attraction are weaker 2)high pressure and low temperature, because particles are forced closer together and moving slower, so the volume of the particles is less significant 3) low pressure and high temperature, because particles are spread farther apart and moving faster, so the intermolecular forces of attraction are weaker 4)low pressure and low temperature, because particles are spread farther apart with lower kinetic energy, so the volume of the particles is less significant
