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?
The mass of carbon dioxide is 141,2 g.
The gram molecular mass of hexane is 86.18. Therefore, 25.0 g of hexane constitute 25.0/86.18 or 0.290 moles. Each mole of hexane contains six carbon atoms and therefore will produce six molecules of carbon dioxide by burning in an excess of oxygen. 6 X 0.290 = 1.74 moles of carbon dioxide. The gram molecular mass of carbon dioxide is 44.00. Therefore, the mass of carbon dioxide produced will be 1.74 X 44.00 or 76.6 grams of carbon dioxide, to the justified number of significant digits.
The mass of carbon dioxide is 878 g.
114,426 g carbon dioxide are produced.

The mass of carbon dioxide is 141,2 g.
0.88g of Carbon dioxide. For every 100g of limestone heated, 44g of CO2 and 56g of CaO are produced.
The gram molecular mass of hexane is 86.18. Therefore, 25.0 g of hexane constitute 25.0/86.18 or 0.290 moles. Each mole of hexane contains six carbon atoms and therefore will produce six molecules of carbon dioxide by burning in an excess of oxygen. 6 X 0.290 = 1.74 moles of carbon dioxide. The gram molecular mass of carbon dioxide is 44.00. Therefore, the mass of carbon dioxide produced will be 1.74 X 44.00 or 76.6 grams of carbon dioxide, to the justified number of significant digits.
The equation for the reaction is C + O2 -> CO2. The relevant gram atomic masses are 12.011 for carbon and 15.9994 for oxygen. Therefore, the ratio of the mass of carbon dioxide produced to carbon burnt is [2(15.9994) + 12.011]/12.011 or about 3.66. From burning 3 grams of carbon, the mass of carbon dioxide produced is therefore 1 X 101 grams, to the justified number of significant digits.

The answer is 24,15 g.
the answer is 356.96 tonnes
Burning 2 700 g of methane produce 70406 g of carbon dioxide.
Carbon dioxide.
carbon dioxide. carbon dioxide.
Carbon Dioxide is produced naturally by the exhalation of air in humans beings and animals.
when carbon dioxide is produced in an aqueous solution, you can see the bubbles floating out of the liquid.
