Question

Question 7: Your friend tells you that they weighed FeNO$_3$ for a reaction. They weighed 2.14g and added this to a 1M solution of arsenic oxide. a) Given what you have heard, what did your friend say incorrectly? (2 marks) b) Give the molecular formula and names for the materials that your friend is working with. (2 marks) c) Are the materials he is working with compounds, elements, mixtures or perhaps something else? Explain in detail. (3 marks) d) Do you think the Fe of the FeNO$_3$ might have isotopes? Why do you think it might or might not have? (2 marks) e) Use an anion that your friend mentioned and give a cation from group 1 on the periodic table. Write the formula and name the compound. (2 marks) f) Write the electron configuration of the metal cation that your friend mentioned. (3 marks) [14 marks]
