Classify the six underlined properties in the following paragraph as chemical or physical:
Fluorine is a pale yellowgas that reacts with most substances. The free elementmelts at -2000C and boils at -188 °C. Finely divided metals burn in fluorine with a bright flame. Nineteen grams of fluorine will react with 1.0 gram of hydrogen.
Explain the difference between extensive properties and intensive properties.
Which produces more heat?
\({\bf{Os}}\left( {\bf{s}} \right) \to {\bf{2}}{{\bf{O}}_{\bf{2}}}\left( {\bf{g}} \right) \to {\bf{Os}}{{\bf{O}}_{\bf{4}}}\left( {\bf{s}} \right)\)
