Mr. Rutherford's chemistry class was collecting data in a neutralization study. Each group had 24 test tubes to check each day for one week. Students had to check to see whether the solution in each test tube was acidic, basic, or neutral. What would be the MOST efficient method for collecting this data and recording it for later analysis? A) pH paper and a notebook B) pH probe linked to a graphing calculator C) photometer linked to a graphing calculator D) phenolphthalein solution and a computer spreadsheet

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.

Areaction is first order with respect to reactant x and second order with respect to reactant y. which statement describes the rate law for this reaction?
