Worked Example of Calculating Molar Enthalpy of Combustion Using Experimental Results. Question: A spirit burner used 1.00 g of methanol to raise the temperature of 100.0 g of water in a metal can from 25.0°C to 55.0°C. Assuming the heat capacity of water is 4.184 J°C-1 g-1, calculate the molar enthalpy of combustion of methanol in kJ mol-1.. Solution:
Cp Molar heat capacity at constant pressure at 298.15 K in J/mol K The standard state pressure is 100 kPa (1 bar). The standard states are defined for different phases by: • The standard state of a pure gaseous substance is that of the substance as a (hypothetical) ideal gas at the standard state pressure.
3 g of a metal oxide is completely converted to its metal chloride and it yields 5 g of metal chloride. Then what is the equivalent weight of the metal? Interesting homework question. Obviously you're looking for help. So I will help you, but you'...
15-08-2020· Stoichiometry and Balancing Reactions. Stoichiometry is a section of chemistry that involves using relationships between reactants and/or products in a chemical reaction to determine desired quantitative data. In Greek, stoikhein means element and metron means measure, so stoichiometry literally translated means the measure of elements.
M(OH)2 + 2HCl --> MCl2 + 2H2O. One mole of hydroxide ions neutralises one mole of hydrogen ions. As one mole of the metal hydroxide neutralises two moles of hydrochloric acid, the metal hydroxide must contain two hydroxide ions in each formula unit.
