The following reaction is used to generate hydrogen gas in the laboratory. If 243 mL of gas is collected at 25°C and has a total pressure of 745 mm Hg, what mass of hydrogen is produced? A possibly useful table of water vapor pressures is provided below. Mg(s) + 2 HCl(aq) → MgCl2(aq) + H2(g)

col1 T (°C) 20 25 30
col2 P (mm Hg) 17.55 23.78 31.86

for points guys

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

your answer would be “dry”
