Use the periodic table to answer this question. decomposing calcium carbonate yields calcium oxide and carbon dioxide. what information is needed to calculate the mass of calcium oxide that can be produced from 4.7 kg of calcium carbonate?

You need the atomic mass of calcium, oxygen and carbo; the balanced chemical equation  and the molar ratio between Calcium carbonate and calcium oxide.

Explanation:

1.- If you know the atomic mass of the elements, you can calculate the molar mass of Calcium Carbonate (CaCO3) and the mass of Calcium Oxide (CaO).

2.- The balanced equation is CaCO3 -> CaO + CO2

3.- The molar ratio between CaCO3 and CaO is 1:1, which means that the descomposing of one mole of calcium carbonate produce one mole of calcium oxide.

4.- The last thing you should do is to conver the 4.7 kg of CaCO3 to moles and with the molar ratio calculate the mass of CaO

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
