Which statement describes the periodic law? metals are both good conductors of heat and electricity. atomic masses always increase across a period. nonmetals are of the most reactive elements. elements in the same group have similar chemical properties.

Which element would mostly likely have an electron affinity measuring closest to zero

What is the most important factor in determining climates.

Consider the following unbalanced equation for the combustion of hexane: αc6h14(g)+βo2(g)→γco2(g)+δh2o(g) part a balance the equation. give your answer as an ordered set of numbers α, β, γ, use the least possible integers for the coefficients. α α , β, γ, δ = nothing request answer part b determine how many moles of o2 are required to react completely with 5.6 moles c6h14. express your answer using two significant figures. n n = nothing mol request answer provide feedback
