How many moles of acetylene gas occupy a volume of 3.25 l at stp?

0.1449 moles of acetylene gas occupy a volume of 3.25 l at STP .

Explanation:

Using ideal gas equation:

PV = nRT

where,

P = Pressure of acetylene  gas =  (at STP)

V = Volume of acetylene  gas = 3.25 L

n = number of moles of acetylene  gas = ?

R = Gas constant = 0.0821 L.atm/mol.K

T = Temperature of gas = 273.15 K  (at STP)

Putting values in above equation, we get:

n = 0.1449 moles

0.1449 moles of acetylene gas occupy a volume of 3.25 l at STP .

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
