Given the mass of the asteroid to be (7.586x10^14) in grams and the diameter of the Earth (1.28x10^4) in km. Calculate the expected distribution of asteroid dust over the surface of the Earth in grams per cubic centimeter(g/cm2). Note: The your answer is assumed to be reduced to the highest power possible.(This means that everything is in scientific notation) When entering units for the answer, use the symbol for the unit, and if the unit has an exponent, enter the exponent as a carat(^). For example, grams would be "g" and, the unit grams per centimeter squared would look like, g/cm^2. %3D Note: Your answer is assumed to be reduced to the highest power possible.

The two must be done independently of each other, as they are completely unlike. A qualitative analysis must always be done before a quantitative analysis. A quantitative analysis must always be done before a qualitative analysis. A qualitative analysis identifies the type of ion in solution and the quantitative analysis will determine how much of this ion is present.

In the first step, aluminum hydroxide reacts to form alumina and water: 2 Al(OH)3(s)-Al₂O3(s) + 3 H₂O(g) 11 In the second step, alumina and carbon react to form aluminum and carbon dioxide: 2 AL₂O3(s)+3 C(s)-4 Al(s) + 3 CO₂(9) Write the net chemical equation for the production of aluminum from aluminum hydroxide and carbon.
