Your unknown will contain between 25-100% calcium carbonate. Answer to 3 significant figures. Do not include the unit, g.
Hint: ( 0.0400 L CO2 ) X ( 1 mol CO2 / 22.4 L ) X ( __ mol CaCO3 / __ mol CO2 ) X ( __ g CaCO3 / 1 mol CaCO3 )
Which statement correctly describes how hydrolysis causes chemical weathering? A. Water reacts with carbon dioxide to produce clay, weakening the rock. B. Water reacts with carbon dioxide to produce carbonic acid, weakening the rock. ~~~~~ C. Water reacts
Methane, CH4 burns in oxygen gas to form carbon dioxide and water. How many moles of carbon dioxide will be formed from 8.0g of methane?
The relative molecular mass of calcium carbonate (CaCO3) is 100. What is the minimum volume of 2.0 M hydrochloric acid (HCl) that would be needed to completely react with 2.0 g of calcium carbonate?
The ocean stores carbon from its interactions with the atmosphere, so the ocean serves as (a) _________ for the carbon cycle. carbon flux carbon dioxide carbon source carbon sink*** Bacteria add carbon to the carbon cycle by decomposing dead organisms.***
Please help! Calculate the standard change in enthalpy, ΔH°rxn, for the decomposition of calcium carbonate to calcium oxide CaCO3 (s) → CaO (s) + CO2 (g) Given that: ΔH°f CaCO3 (s) = -1206.9 kJ/mol ΔH°f CaO (s) = -635.1 kJ/mol ΔH°f CO2 (g) =
1.Cell respiration glucose is reacted wth oxygen in body to produce carbon dioxide and water how many liters of carbon dioxide would be produced if 90.0 g of glucose completely reacts with oxygen C6H12O6(s)+ 6O2(g) -> 6H2O(g) + 6CO2 (g) How many liters of
3. How would the carbon cycle be affected if all producers were removed? (1 point) Carbon compounds in animals would not be broken down to release carbon dioxide back into the atmosphere. Carbon would not have a way to enter the bodies of living things.
When 0.100 mol of carbon is burned in a close vessel with 8.00g of oxygen, how many grams of carbon dioxide can form? Which reactant is in excess, and how many grams of it remain after the reaction?
A 1.00 g sample of limestone is allowed to react with 100 cm^3 of 0.200 mol/dm^3 HCl. The excess acid required 24.8 cm^3 of 0.100 mol/dm^3 NaOH solution. Calculate the percentage of calcium carbonate in the limestone
When heated at high temperature, sodium carbonate, Na2CO3decomposes to sodium oxide and carbon dioxide gas. A sample of 587.3 mL gas was collected using water displacement method at 27 °C at a total pressure of 760 mm Hg and vapour pressure of water is 28
