When elemental carbon is burned in the open atmosphere, with plenty of oxygen gas present, the product is carbon dioxide. C(s)+O2(g) -> CO2(g) However, when the amount of oxygen present during the burning of the carbon is restricted, carbon monoxide is more likely to result. 2C(s)+O2(g) -> 2CO(g) What mass of each product is expected when a 8.60 g sample of pure carbon is burned under each of these conditions? ____g CO2 ____ g CO
1. 16.50 g of glucose, C6H12O6 was burned in the presence of excess oxygen, calculate the volume of CO2(g) that is produced at STP? C6H12O6(s) + 602(g) + 6CO2(g) + 6H2O(g) 2. What volume of 0.250 M HCl is required to completely react with 0.350 g of Na2CO3? Na2CO3(s) + 2HCl(aq) + 2NaCl(aq) + H2O(l) + CO2(g) 3. Calcium carbonate decomposes at high temperatures to give calcium oxide and carbon dioxide. What volume of CO2 will be collected at 950...
When 57.3 g of ethyl alcohol, C_2H_5OH is completely burned, what volume of CO_2 is produced at a pressure of 1.62 atm and 32 degree C? C_2H_5OH + O_2 rightarrow CO_2+H_2O
please work out problem with example
Calculate the volume of CO2(g) formed at STP when 75.0 g of Cacos(s) reacts with 125 mL of 8.00 M HCl(aq). Mol Mass CaCO3 = 100. g/mol. STP = exactly OC and 1 atm pressure (Hint: Is the equation balanced?) HCl(aq) + CaCO3(s) - CaCl(aq) + CO2(g) + H20(1) n= mass/mol mass; MV = n;
When C_2H_2 is burned in air, carbon dioxide and water are formed in the following reaction: C_2H_2+O_2(g) right arrow CO_2(g) + H_2O(l) delta H =-1300. kJ C(s) + O_2(g) right arrow CO_2(g)delta H =-394. kJ; H2(g) +1/2 O_2(g)right arrow H_2O(l) delta H =-286. kJ; Calculate delta H for 2C(s) + H_2(g) right arrow C_2H_2(g) Delta H = what is the heat of formation of H_2o(l) deltaHf
