in the first 14.0 of the reaction 1.9times10?2 of is produced in a reaction vessel with a volume of 0.470. what is the
A 3.46 g sample of zinc heated to 95.4 C was dropped into 50 g of water at 20.7 C in a calorimeter. The temperature rose to 21.2 C. What is the specific heat of zinc?
What is the balanced net ionic equation for magnesium metal
Explain what is the molar Gibbs free energy for the formation of water vapor from hydrogen gas as well as oxygen at 400K
If we assume that the volume change is due entirely to this density change (that is we neglect thermal expansion of the ice/water), what is the difference between the enthalpy change and the energy change during theis process? Is this a significan..
Use the balanced chemical equation you wrote in question #1 to determine how many moles of carbon monoxide are produced from 0.654 mol of carbon.
Determine the electronegativity between the atoms
A mixture of 0.10 mol of NO, 0.050 mol of H2 as well as 0.10 mol of H20 is placed in a 1.0L vessel at 300K. The subsequent equilibrium is established 2NO(g)+2H2(g) N2(g) and 2H20(g) at equilibrium [NO]=0.062M.
Identify the specific independent and dependent variables that will be involved in an experiment to test this hypothesis.
