Answer:
Physical Property
Explanation:
Density, mass, volume, color, melting and boiling points, etc. are all physical properties. No matter what changes, the chemical makeup stays the same.
Flamability, acidity, toxicity, etc. are chemical properties, because they chemically change the makeup of the object/thing.
methanol:
1 mole CH3 OH --> produces --> 1 mole CO2
1 mole CO2 has a molar mass of 44.01 gh/mole
your set up is:
(44.01 g CO2) / -726.5kJ = 0.06058g
your answer 0.06058 grams of CO2 produced per kJ released.
Answer: There are
molecules
gas are in 756.2 L.
Explanation:
It is known that 1 mole of any gas equals 22.4 L at STP. Hence, number of moles present in 756.2 L are calculated as follows.

According to mole concept, 1 mole of every substance contains
molecules.
Therefore, molecules of S present in 33.76 moles are calculated as follows.

Thus, we can conclude that there are
molecules
gas are in 756.2 L.
