Exactly 1.5g of soil is saturated with 100 ml of 1 m kcl. at the end of the saturation, the solution is analyzed, and the following results obtained: ca = 0.50 mg/l; mg = 1 mg/l; na = 1.5mg/l; al = 2 mg/l. if this represent all of the exchangeable ions that were initially on the soil, what is the cec and base saturation in men/100g?

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

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution
