Answer:
0.00001= 1 x 10^-5. Since HCl is an acid, 1 x10^-5 is the H+ concentration. Write only the number of the exponent. Therefore, pH = 5.
Standard Molar Volume is the volume occupied by one mole of any gas at STP. Remember that "STP" is Standard Temperature and Pressure. Standard temperature is 0 &176:C or 273 K. Standard pressure is 1 atmosphere or 760 mm Hg (also called "torr"). 1 mole of any gas at STP occupies 22.4 liters of volume.
HEY THERE!
THE ANSWER IS: the properties of an ideal gas are: An ideal gas consists of a large number of identical molecules. The volume occupied by the molecules themselves is negligible compared to the volume occupied by the gas. The molecules obey Newton's laws of motion, and they move in random motion.

Correct option:
The correct name for 
is diphosphorus pentoxide.
Why is called diphosphorus pentoxide?
is commonly known as diphosphorus pentoxide.
Phosphorus pentoxide has an intriguing property in that is actually its empirical formula, whereas 
is its actual molecular formula.
However, the name of the chemical was obtained from its empirical formula rather than from its molecular formula. The official name for this substance is diphosphorus pentoxide.
Oxygen-containing binary compounds have "oxide" as their "last name." Phosphorus is the "first name."
We list each atom's numbers below:
The di- and Penta- prefixes are used to indicate the presence of two and five oxygen atoms, respectively, in the molecule.
