There are several tests, ranging from a product test (react the sample with acid and then find out what is produced) to a phase test (heat a sample to the midpoint of the melting points of the "suspects" and observe its state).
What else can I help you with?
What mass of calcium oxide is produced by heating 25 moles of calcium carbonate?
The molar ratio between calcium carbonate and calcium oxide is 1:1. So, 25 moles of calcium carbonate will produce 25 moles of calcium oxide. The molar mass of calcium oxide is 56.08 g/mol, so the mass of calcium oxide produced will be 25 moles * 56.08 g/mol = 1402 g.
Predict the most likely products formed from the reaction between calcium carbonate and sodium metal?
The reaction between calcium carbonate and sodium metal is likely to produce calcium oxide, sodium carbonate, and carbon as products. Calcium oxide is formed from the decomposition of calcium carbonate, while sodium carbonate is formed from the reaction of sodium metal with carbon dioxide released from the decomposition of calcium carbonate. Carbon is produced as a byproduct.
What information is needed to calculate the mass of calcium oxide that can be produced frrom 4.7 kg of calcium carbonate?
To calculate the mass of calcium oxide produced from 4.7 kg of calcium carbonate, you need to know the molar mass of calcium carbonate (CaCO3) and calcium oxide (CaO), as well as the stoichiometry of the reaction between these two compounds. This information will allow you to determine the theoretical yield of calcium oxide that can be obtained from the given mass of calcium carbonate.
What is the balanced chemical equation for Calcium carbonate calcium oxide plus hydrogen?
The balanced chemical equation for the reaction between calcium carbonate (CaCO3) and hydrogen (H2) to form calcium oxide (CaO) is: CaCO3 + H2 -> CaO + CO2
What most likely product is formed from the reaction between calcium carbonate and sodium metal?
The reaction between calcium carbonate and sodium metal would likely produce calcium oxide, sodium oxide, and carbon. The calcium oxide and sodium oxide would be the main products, with carbon formation as a byproduct.
The most likely products formed from the reaction between calcium carbonate and sodium metal?
The most likely products formed from the reaction between calcium carbonate and sodium metal are calcium oxide (CaO) and sodium carbonate (Na2CO3). Calcium carbonate will react with sodium metal to form calcium oxide, sodium carbonate, and carbon in the form of soot.
Does calcium carbonate decompose to make calcium oxide and water?
Calcium oxide, or quicklime, can be decomposed chemically into its components, calcium and oxygen. Calcium is an element and cannot be decomposed chemically.
What is formed when calcium carbonate decomposes?
quicklime (calcium oxide) is formed when calcium carbonate decomposes, as well as releasing carbon dioxide
What is the empirical formula for calcium carbon and oxide?
Calcium = Ca Carbon = C oxide = O(2-) Calcium carbonate = CaCO3
What is the difference between calcium carbonate and calcium oxide?
Calcium oxide is a compound of calcium and oxygen and has the formula CaO. It is very basic (alkaline) and will react with water to form calcium hydroxide, Ca(OH)2 which is a strong base. Calcium oxide is commonly called lime or quicklime.Calcium carbonate is a compound of calcium, carbon, and oxygen with the formula CaCO3. It is mildly basic and will not react with water nor is it water soluble. It is commonly called calcite, limestone, or marble.
What is the equation for heating calcium carbonate?
Calcium carbonate --> Calcium oxide + Carbon dioxide Its an example of thermal decomposition.
What is the name of the solid formed when calcium carbonate decomposes?
Thermal decomposition of calcium carbonate release calcium oxide (CaO).
