09042011 Energy Planks constant frequency E h f In the equation E represents energy and has the units of Joules J f stands for frequency and has the units of Hz and h represents what they call Planks constant. Chemical Formula Percent Composition of a Compound The subscripts in the formula are used to calculate the mass of each element in a mole of that compound. Translating the English and using the usual chemical symbols for the compounds you might be tempted to write something like this.

2 atoms x 101 amu Cl. The ratio of moles of P. PowerPoint PPT presentation free to view.

38 rows C 6 H 12 O 6 O 2 CO 2 H 2 O energy. 02062011 H-H 436 kJmol. T is usually room temperature 298 K.

TYPES OF COMPOUNDS Ionic Compounds cont Examples NaCl CaBr2 KI CHEMICAL FORMULAS Definition shows the kind and numbers of atoms in the smallest representative unit of the substance. Calorimetry is the measuring of changes in heat energy in units of calories. 464 1856 kJ mol-1 there are two O-H bonds in each water molecule Energy change in - out 1370 - 1856 -486 kJ mol-1.

The conversion factor is just 1571 in which the mass units are explicitly stated. To calculate bond energy for molecules in a liquid state you need to also look up the enthalpy change of vaporization for the liquid molecule. To calculate percent composition Percent Composition of Water.
