Hi:) for questions 8 & 9 , anyone able to explain why nitrogen is N2 instead of N. also why is chlorine cl2 instead of c1? Thank you!

Which substance has non polar covalent bonds

For the reaction shown, find the limiting reactant for each of the following initial amounts of reactants. 4al(s)+3o2(g)→2al2o3(s) a) 1 molal, 1 mol o2 b) 4 molal, 2.6 mol o2 c) 16 molal, 13 mol o2 d) 7.4 molal, 6.5 mol o2

How do limiting factors most affect population size? ostop population growthrestrict population growthincrease population sizeresult in positive impactso
