WILL GIVE BRAINLIEST AND 20 POINTS! Barium hydroxide, often used to titrate weak organic acids, is obtained as the octahydrate, Ba(OH)2 * 8 H2O. What mass of Ba(OH)2 * 8 H2O would be required to make 500 mL of a solution that is 0.1500 M hydroxide ions? [hint: calculate the molar mass of barium hydroxide octahydrate].

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
