CHM 101 A novel process for obtaining magnesium from sea water involves several reactions. CHM 101 A novel process for obtaining magnesium from sea water involves several reactions. Write a balanced chemical equation for each step of the process. (Use the lowest possible whole number coefficients. Include states-of-matter under the given conditions in your answer.)(a)The first step is the decomposition of solid calcium carbonate from seashells to form solid calcium oxide and gaseous carbon diox...

CHM 101 Identify the atoms that are oxidized and reduced, the change in oxidation state fo CHM 101 Identify the atoms that are oxidized and reduced, the change in oxidation state for each, and the oxidizing and reducing agents in the following equation.Zn(s) + H2SO4(aq) †’ ZnSO4(aq) + H2(g)Oxidation-Reduction ReactionsIn the given reaction:Zn(s) + H2SO4(aq) †’ ZnSO4(aq) + H2(g)We can identify the atoms that are oxidized and reduced, the change in oxidation state for each, and the oxidiz...

CHM 101 When ionic compounds dissolve in water, they break apart into their component ions CHM 101 When ionic compounds dissolve in water, they break apart into their component ions.  Remember that some ions are monatomic ions, and others are polyatomic ions.  You will need to recognize polyatomic ions when they are part of the formula for an ionic compound.   For example, one formula unit of Na2CO3 contains three ions:  2 Na+ ions and 1 CO32- ion. How many ions are in just one formula ...

CHM 101 The compound methanol consists of carbon, oxygen, and hydrogen. A 5.000-gram sampl CHM 101 The compound methanol consists of carbon, oxygen, and hydrogen. A 5.000-gram sample of methanol contains 1.875 g carbon. What is the mass of carbon in a 100.0-gram sample of methanol? (This is the same as determining the mass percent composition of carbon.)The mass percent composition of an element in a compound is calculated by dividing the mass of the element by the total mass of the compound an...
