Will give brainyest!how do the three surfaces compare in terms of providing the egg with a safe landing? which ordering below ranks the three surfaces from least safe to most safe? a.) foam box < 1 inch foam < hard floor b.) hard floor < foam box < 1 inch foam c.) hard floor < 1 inch foam < foam box d.) 1 inch foam < foam box < hard floor

answer; i believe that the correct answer is (a) potassium(k)

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
