The balanced reaction between aqueous nitric acid and aqueous strontium hydroxide is a. hno3(aq) + sr(oh)2(aq) → sr(no3)2 (aq) + h2 (g) b. hno3(aq) + sr(oh)2 (aq) → h2o (l) + sr(no3)2 (aq) c. hno3 (aq) + sroh (aq) → h2o (l) + srno3(aq) d.2hno3 (aq) + sr(oh)2 (aq) → 2h2o (l) + sr(no3)2(aq)

The big bang nucleosynthesis theory states that elements were produced in the first few minutes of the big bang while elements have their origins in the interiors of stars, forming much later in the history of the universe.

How do i complete this electrolysis of water lab? i’m at home, so i don’t have the materials, and the lab didn’t properly work and was incomplete at school.

)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.
