Locate the row containing lithium (Li), sodium (Na), potassium (K), rubidium (Rb), and cesium (Cs). Look up these elements in the periodic table, and click each element to reveal its properties. Explain why Mendeleev might have grouped these elements together.

How do dying stars contribute to the formation of planets

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
