In the early days of automobiles, illumination at night was provided by burning acetylene, C2H2. Though no longer used as auto headlamps, acetylene is still used as a source of light by some cave explorers. The acetylene is (was) prepared in the lamp by the reaction of water with calcium carbide, CaC2:CaC2(s) + 2H2 O(l) ⟶ Ca(OH)2(s) + C2 H2(g).Calculate the standard enthalpy of the reaction. The ΔH°f of CaC2 is −15.14 kcal/mol.
One method used in the production of H2 gas is to put the coal into an incomplete combustion reaction with air and water vapor in the combustion chamber (water gas production).
A simplified reaction can be written as:2C + 1 H2O + a (O2+3.76N2) = 1C0 + 1CO2 + 1H2 + 3.76·a·N2
Here, 02+3.76N2 represents the amount of air and is multiplied by the coefficient "a".a) The value of the coefficient "a" for this reaction
b) The amount of air to be used for 1 kg of pure carbon (C) (total amount of 02 and N2) (kg-air/kg-carbon)
Hint: Consider how many kilograms 1 kmol "C" weighs.
Q) Drinking water may contain several unwanted ions such as phosphate ions. In order to remove the phosphate ions from the drinking water, a solution of calcium hydroxide can be added. As a result, a solid Ca5OH(PO4)3 is formed and isolated by filtration and a hydroxide ion are also formed. The reaction for this process is below:
5 Ca(OH)2 (aq) + PO43- (aq) → Ca5OH(PO4)3 (s) + OH- (aq)
a) If 3.00 mL of 0.100 M calcium hydroxide is mixed with 4.00 mL of an aqueous solution of 0.0800 M phosphate ions (PO43-). What is the mass of Ca5OH(PO4)3 that can be isolated from the reaction?
b) How many moles of the excess reactant remains unreacted?
c) What is the concentration of the hydroxide ions in this solution?
d) What is the mass of calcium (in grams) that can be recovered?
