Calcium carbonate decomposes into calcium oxide & carbon dioxide Her results:Mass of calcium carbonate before heating = 2.00 g Mass of calcium oxide left after heating = 1.12 g work out the mass of carbon dioxide released during the decomposition?
I am not sure of the answer so can someone help me pls
What mass of carbon dioxide is produced when 200 tons of calcium oxide is made?
the answer is 356.96 tonnes
What is the percent mass of calcium in a calcium supplement if 1.35-g of calcium carbonate is extracted from a 2.36-g pill?
The molar mass of calcium carbonate (CaCO3) is 100.09 g/mol. To calculate the percent mass of calcium, you need to divide the molar mass of calcium (40.08 g/mol) by the molar mass of calcium carbonate. This gives you a result of 0.4006, meaning that calcium constitutes approximately 40.06% of the mass of calcium carbonate.
Does the mass of calcium oxide effect the temperature rise when calcium oxide reacts with water?
yes
What is the mass of lithium oxide made from 20g of lithium carbonate?
The mass of lithium oxide (Li2O) is 8,o9 g.
What mass of calcium oxide is produced by heating 25 moles of calcium carbonate?
1400 grams
What information is needed to calculate the mass of calcium oxide that can be produced frrom 4.7 kg of calcium carbonate?
molar masses of calcium, carbon, oxygen

If you heated limestone how would you expect the mass of the limestone to compare with the mass of calcium oxide?
When you heat limestone it becomes calcium oxide but if you mean calcium carbonate then it should go down slightly due to the release of CO2
What mass of carbon dioxide is produced when 200 tons of calcium oxide is made?
the answer is 356.96 tonnes
When 100kg of calcium was completely decomposed 44kg of carbon dioxide was given off what is the mass of calcium oxide produced?
I need to know?
How can calculate equivalent weight of calcium carbonate?
Molar mass of calcium carbonate/calcium valence = 50,04345
What drugs that involve with the mass of calcium carbonate?
Many antacids and calcium supplements contain calcium carbonate.
What is the percent mass of calcium in a calcium supplement if 1.35-g of calcium carbonate is extracted from a 2.36-g pill?
The molar mass of calcium carbonate (CaCO3) is 100.09 g/mol. To calculate the percent mass of calcium, you need to divide the molar mass of calcium (40.08 g/mol) by the molar mass of calcium carbonate.

How many moles of calcium oxide are produced when 36.5 grams of calcium reacts completely with oxygen gas?
2Ca + O2 --> 2CaO The molar mass of Calcium is 40g/mol. 36.5g/40g gives you 0.9125 moles of Calcium. The moles of calcium are equivalent to the moles of Calcium oxide. The answer is 0.9125 moles of calcium oxide. Correct me if I am wrong.
What mass of carbon dioxide will be produced?
Full question: Ordinary chalkboard chalk is a solid mixture with limestone (calcium carbonate) and gypsum (calcium sulfate) as its principal ingredients. The limestone dissolves in dilute hydrochloric acid, producing calcium chloride, carbon dioxide, and water. 1.) Gypsum does not react with HCl. If a 5.05g piece of chalk that is 72.0% calcium carbonate is dissolved in excess HCl, what mass of carbon dioxide will be produced? 2.) Determine the mass percent of calcium carbonate in a 4.38g piece of chalk that yields 1.31g carbon dioxide when it reacts with excess HCl?
Does the mass of calcium oxide effect the temperature rise when calcium oxide reacts with water?
yes
