After a few minutes, a white compound was found to have formed on the silver strip, coating it uniformly. 9342 grams. Finally, she washed the coated strip with distilled water, removing all of the white compound from the silver strip, and then dried the compound and the strip and reweighed. 3258 grams. (a) Show how she would determine (1) the number of moles of chlorine gas that reacted (2) the number of moles of silver that reacted (b) Show how she could determine the simplest formula for the silver chloride.
5. A test tube containing CaCO3 is heated until all of the compound decomposes. 400 grams, what was the mass of the empty test tube? A. 07 g B. 00 g C. 50 g D. 08 g E. 68 g Answer: A Begin by writing a balanced equation. Remember that all Group II carbonates decompose to yield the metallic oxide plus carbon dioxide gas. CaCO 3 ^ sh " CaO ^ sh + CO 2 _ g i According to your balanced equation, any loss of mass during the experiment would have to have come from the carbon dioxide gas leaving the test tube.
The advantages of this format are that it does not require full sentences and that it progresses in a logical sequence. The disadvantage is that it requires you to spend more time thinking about organization. Leave plenty of room here because you may want to come back later and add more points. 01 Discuss the relationship among the composition, the boiling point, and the electrical conductivity of each solution. Answer 3. 05 m. P. and electrical conductivities. I. ) A. BaSO4 is an ionic compound.
