Chapter 1 question 7 There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. +CaC2s2H2Ol ⇌ +C2H2gCaOH2s K1 +6C2H2g+3CO2g4H2Ol ⇌ 5CH2CHCO2Hg K2 The net reaction is: +6CaC2s+16H2Ol3CO2g ⇌ +6CaOH2s5CH2CHCO2Hg K Write an equation that gives the overall equilibrium constant K in terms of the equilibrium constants K1 and K2.
Identifying the major species in weak acid or weak base equilibria 075 The preparations of two aqueous solutions are described in the table below. For each solution, write the chemical formulas of the major species present at equilibrium. You can leave out water itself. Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and the formulas of the species that will act as neither acids nor bases in the 'other' row. You will find it useful to keep in mind that HCN is a weak acid. acids: 0.4 mol of NaOH is added to 1.0 L of a 0.9 M HCN solution. bases: other: 0.59 mol of HNO3 is added acids: to 1.0 L of a solution that is bases: 1.2M in both HCN and NaCN. other: ☐ ☑ 0,0,... ? ملام 18 Ar

1. For the reaction below draw a curve in the space provided that represents the effect that each of the following changes would have on the concentration of the reactants and products. Be sure to label your curve properly for ease of marking. NH3(aq) + H2O(l) ↔ NH4 + (aq) + OH- (aq) + heat Start: Equilibrium is approached from the reactant side and favours the reactants. Case 2: NH3(aq) is removed. Case 3: The temperature of the system is decreased. Case 4: MgCl2 is added need all 4 parts clearly or else I will downvote don't copy strictly
