Calcium carbonate decomposes on heating as shown CaCO3 CaO + CO2. Theoretically, 35 g of calcium oxide was expected to be produced but only 7g of
calcium oxide was experimentally obtained. What is the percentage yield of calcium
oxide?

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
