A scientist completes a thermal decomposition reaction. 12.25g of calcium carbonate, CaCO3, is heated and forms calcium oxide, Cao, and carbon dioxide, CO2.
a. Write a balanced chemical equation to demonstrate this reaction. Include state symbols.

b. Calculate the number of moles of calcium carbonate that is thermally decomposed in this
reaction.
Ok

Moles of calcium carbonate : 0.1225

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

CaCO₃(s) → CaO(s) + CO₂(g)

mass of CaCO₃ : 12.25 g

mol CaCO₃(MW=100 g/mol) :

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
