Question 14 **Question 14 of 14**A sample weighing 3.168 g is a mixture of Fe₂O₃ (molar mass = 159.69 g/mol) and Al₂O₃ (molar mass = 101.96 g/mol). When heat and a stream of H₂ gas is applied to the sample, the Fe₂O₃ reacts to form metallic Fe and H₂O(g). The Al₂O₃ does not react. If the sample residue (the solid species remaining after the reaction) weighs 2.380 g, what is the mass fraction of Fe₂O₃ in the original sample?**mass fraction:** [_______________] g Fe₂O₃ / g original sample

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.
