Astudent tested a sample of carbon (c) by combining it with water. there was no reaction between the carbon and water. the student concluded that carbon must be a group 18 element, since it was unreactive. is this conclusion correct? why or why not? no. the carbon probably did react, but did not give off any signs or indications of a chemical change. no. just because carbon did not react with water, does not mean it wouldn’t react with a different compound. yes. the student can make a reasonable conclusion based on one experiment. yes. water would react with almost every element, except group 18 elements.

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
