Answer:
We will derive the combined gas equation from the law of Gases
Boyle's law
P∝1/V
PV=Constant
Charles law
V∝T
Avogadro's Law
V∝n
By combining these three equations we get the combined gas equation
PV=nRT
V=nRT/P
If n=1 mole
V=RT/P
By putting the value of R, T, and P in the above equation we can calculate the volume of the gas at STP.
Answer:
gallium (Ga)
Explanation:
the elements which have fewer than four dots in the electron dot diagrams. Explanation: Electron dot diagrams are the diagrams which represent the valence electrons in an element. The electrons are represented by the dots in these diagrams.
of oxygen at STP would be required to react completely with 38.8g of propane.
<u>Given that :</u>
molar mass of propane = 44 g/mol
mass of propane = 38.8 g
∴ Moles present in 38.8 g of propane = 
= 0.88 mole
<u>applying rule of balanced equations </u>
1 mole of propane = 5 moles of oxygen
0.88 mole of propane = 5 * 0.88 = 4.4 moles of oxygen
Note : volume of 1 mole of oxygen at STP = 
∴Total volume of oxygen required at STP = 22.4 * 4.4 =
Hence we can conclude that the volume of oxygen at STP required to react completely
