The model below shows a carbide ion. 8 light grey and 6 dark grey balls sit at the center with 2 concentric black rings around them. the inner ring has 2 medium grey balls on it, and the outer ring has 8 medium grey balls on it. at bottom, a dark grey ball = +1, a light grey ball = 0, a medium grey ball = negative 1. what could be done to change this carbide ion to a neutral carbon atom? remove 2 electrons add 2 electrons remove 4 electrons add 4 electrons

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
