Question- Carbon dioxide dissolves in water to form carbonic acid, which is primarily dissolved CO2. Dissolved CO2 satisfies the equilibrium equation. The acid dissociation constants listed in most standard reference texts for carbonic acid actually apply to dissolved CO2. For a CO2 partial pressure of 7.7×10-4 bar in the atmosphere, what is the pH of water in equilibrium with the atmosphere? (For carbonic acid Ka1 = 4.46× 10-7 and Ka2 = 4.69× 10-11).
I want you to explicate the chemistry in this problem
Safrole is used as a topical antiseptic. Calculate the vapor pressure of a solution prepared by dissolving 0.75 mol of safrole in 950 g of ethanol ( molar mass = 46.07 g/mol). P°ethanol = 50.0 torr at 25°C
The reading on the tank pressure initially rises very quickly then much more slowly eventually reaching a value of 3.27 mpa. A ssume T final=19C. How many moles of air in the tank initially ?

Design an experiment to determine the density of irregular shaped object. a. Include an introduction describing the calculations that will need to be made.
Diamond has a face-centered cubic unit cell, with four more C atoms in tetrahedral holes within the cell. Densities of diamonds vary from 3.01 g/cm3 to 3.52 g/cm3 because C atoms are missing from some holes.
An extraction procedure specifies that an aqueous solution containing dissolved organic material be extracted twice with 10-mL portions of diethyl ether.
