1. 849 mg of a pure diprotic acid (this means that the acid is capable of donating two nydrogen ions or protons) was titrated with 12.32 mL of a 0.684 M potassium hydroxide solution. What is the molar mass of the acid? The balanced equation is: H2X 2 KOH K2X +2 HOH 2. The molarity of sulphuric acid in a fully charged car battery is 5.2 M. When fully discharged the molarity is 4.8 M. A 2.00 mL sample of battery acid was titrated with 31.26 mL of a 0.621 M sodium hydroxide solution. Does the battery need to be recharged? In the vernacular, what is the molarity of the battery acid? Document your answer. 3. A student titrated 38.00 mL of a 0.522 M sodium hydroxide solution with 25.00 mL of a 0.785 M hydrochloric acid solution. Which is the limiting reagent? How many mL of excess reactant will remain?

Discuss the language demands included in the lesson on mixing substances in a 5th-grade classroom by Identifying key vocabulary terms students must know in order to master the learning objectives for the lesson based on the below standard and learning objective. Standard Conduct an investigation to determine whether the mixing of two or more substances results in new substances. Learning Objective Given a variety of substances and safety equipment in a classroom setting, students will be able to conduct an experiment to mix two or more substances and observe the results. They will be able to correctly identify whether a new substance has been formed as a result of the mixing, based on observable changes such as color change, formation of a precipitate, or change in temperature, with at least 80% accuracy.
