Sulfuric acid (H2SO4) and Ba(OH)2 solutions are strong electrolytes and give a bright glow on the light bulb of your conductivity apparatus. When Ba(OH)2 is added dropwise to H2SO4, a precipitate is formed and the light bulb of the conductivity apparatus dims and eventually fades completely. Required:
a. Briefly explain this phenomenon.
b. Write the balanced equation of the reaction between these solutions.

Draw the lewis structure for the trisulfur s3 molecule. be sure to include all resonance structures that satisfy the octet rule.

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
