Does the mass of calcium oxide effect the temperature rise when calcium oxide reacts with water?
yes
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 formula mass of CaO?
This is calcium peroxide. You have to be careful... one might be tempted to call this calcium oxide, but oxygen normally has a charge of 2-, and since Ca always forms Ca2+, this is not calcium oxide because its formula would be CaO (Ca2+ and O2-). So the anion here is O22-, which is the polyatomic anion peroxide. ***************************************************************** The above response may be what you're looking for, but being in the medical profession, I see CaO2 as the formula to calculate Content of arterial oxygen. Therefore, the formula for this is: (Hb x 1.34 x %SaO2) + (PaO2 x 0.003) PaO2 should be in decimal form, PaO2 you can obtain from the ABG.
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 Molar mass for calcium oxide?
The molar mass of calcium oxide is 56.077 grams per mole
A mass of 21.5 grams of calcium hydroxide reacts with an excess of phosphoric acid What mass of calcium phosphate could be recovered from solution?
31.6grams
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 calcium oxide is produced by heating 25 moles of calcium carbonate?
1400 grams
Does the mass of calcium oxide effect the temperature when it reacts with water?
yes
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.
Is the volume of the unknown mass needed to calculate the mass of calcium oxide?
No. you will know the volume of the unknown mass after you calculate the mass of ca0
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?

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
What is the salt type of calcium oxide?
It is an OXIDE-salt, although it normally is not called a 'salt' but an 'oxide'. But strictly speaking it IS a salt like eg. CaS (calcium sulfide) CaO, calcium oxide, dry chalk, used as dry desinfectant eg. in mass graves slightly soluble in water, forming calcium hydroxide Ca(OH)2
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?
