False. Alkaline earth metals react with oxygen.
Answer:
Solid = rocks or other hard stuff
Liquid = water or mild or other stuff likt that
1 cm ------------ 10 mm
5,678 cm ------- ?
5,678 x 10 / 1 => 56,78 mm
Given:
Sulfur dioxide and dihydrogen sulfide system
Vapor Pressure of water, H2O = 23 torr
P_SO2 = P_H2S
Temperature of the system = 298 K
Assume: Total pressure of the system is 1 atm = 760 torr
If partial pressure of SO2 is equal to the concentration of H2S, then,
760 = 0.5*PSO2 + 0.5PH2S
760 = PSO2
Lithium forms a +1 ion because it loses one electron, making the ratio of electrons:protons unbalanced by losing one electron. the ratio is now 2e:3p.
Oxygen forms a -2 ion because of a different reason. It gains 2 electrons rather than losing them.
