3. use your answers from 2 above and hess’s lawton determine the experimental molar enthalpy for reaction three.

4. use hess’s law, and the accepted values of change of h in the pre-lab exercise to calculate the change in h for reaction 3. how does the accepted value compare to your experimental value?

b

explanation:

mitosis

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
