PLEASE ANSWE Now that conservationists have intervened, the population of the yellow-breasted throat warbler is
expected to triple every 4 years. In 2013 there only 12 in existence, in how many years will there 360
in existence?

If 200.0g of copper(ll) sulfate react with an excess of zinc metal, what is the theoretical yield of copper

Which type of precipitation would most likely form when the surface air temperature is slightly below freezing and the air temperature increases as you move upward away from the ground?

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
