Answer:
H₂ is excess reactant and O₂ the limiting reactant
Explanation:
Based on the chemical reaction:
2H₂(g) + O₂(g) → 2H₂O
<em>2 moles of H₂ react per mole of O₂</em>
<em />
To find limiting reactant we need to convert the mass of each reactant to moles:
<em>Moles H₂ -Molar mass: 2.016g/mol-:</em>
10g H₂ * (1mol / 2.016g) = 4.96 moles
<em>Moles O₂ -Molar mass: 32g/mol-:</em>
22g O₂ * (1mol / 32g) = 0.69 moles
For a complete reaction of 0.69 moles of O₂ are needed:
0.69mol O₂ * (2mol H₂ / 1mol O₂) = 1.38 moles of H₂
As there are 4.96 moles,
<h3>H₂ is excess reactant and O₂ the limiting reactant</h3>
Answer:
Iron and chlorine form an ionic compound whose formula is FeCl3. The name of this compound is iron (III) chloride or iron trichloride.
Explanation:
Iron (III) chloride or Iron trichloride is also known as ferric chloride, it is a common compound of iron in the +3 oxidation state. The anhydrous compound is a crystalline solid with a melting point of 307.6 °C.
Pressure of the ideal gas=505.7kPa
Given:
No of moles=0.907mole
Temperature of the gas=
Volume of the gas=4.25L
To find:
Pressure of the gas
<u>Step by Step Explanation:
</u>
Solution:
According to the ideal gas equation
and from this pressure is derived as

Where P=Pressure of the gas
V=Volume of the gas=4.25L
n=No of the moles=0.907mole
R=Gas constant=8.314
T=Temperature of the gas=
=273+12=285K
Substitute these known values in the above equation we get

P=505.7kPa
Result:
Thus the pressure of the ideal gas is 505.7kPa
