A 500-cm3 sample of 1.0 M NaOH(aq) is added to 500 cm3 of 1.0 M HCl(aq) in a Styrofoam cup, and the solution is quickly stirred. The rise in temperature (ΔT1) is measured. The experiment is repeated using 100 cm3 of each solution, and the rise in temperature (ΔT2) is measured. What conclusion can you draw about ΔT1 and ΔT2?HCl(aq) + NaOH(aq) → H2O(l) + NaCl(aq); ΔH° = –55.8 kJ

can you list the answers so i can answer

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )

a corroding iron, if that's one of your choices
