1) A chemist was deciding what chemical to use in a handwarmer. She studies 2 compounds. One is a nonpolar covalent compound that is safe and nontoxic. The other is an ionic compound. It is poisonous if ingested. What tests could she do to tell them apart? Give two possible observations or tests she can run to verify the substance. Which substance would you use to make the handwarmer and why?

Calculate: select the worksheet tab. this tab you calculate the analyte concentration.  fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.)  record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes.  record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed
