The Henry's law constant for N2 in water is 0.00104 M/atm. The solubility of N2 in water is 0.00218M. What is the partial pressure of nitrogen above water in atm

introduction of a drug directly into the respiratory tract is a form of inhalation administration.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

1 is the answer to this problem

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
