against at -20 degree centigrade occupied the volume of one 40 ml calculate the temperature at which the volume of cash pickup 6
1 answer:
The final temperature :T₂=411.125 K = 138.125 °C
<h3>Further explanation</h3>Given
T₁=-20 °C+273 = 253 K
V₁=40 ml
V₂=65 ml
Required
Final temperature
Solution
Charles's Law
When the gas pressure is kept constant, the gas volume is proportional to the temperature
Input the value :
T₂=(V₂.T₁)/V₁
T₂=(65.253)/40
T₂=411.125 K = 138.125 °C

<u>Answer:</u> Amount of iron produced is 101.36 grams.
<u>Explanation:</u>
For the reaction of aluminium and iron oxide, the equation follows:
By Stoichiometry of the reaction,
When 1 mole of aluminium oxide is produced, then 2 moles of iron is also produced.
So, when 0.905 moles of aluminium oxide is produced, then of iron is also produced.
Now, to calculate the amount of iron produced, we use the equation:
Molar mass of iron = 56 g/mol
Moles of iron = 1.81 moles
Putting values in above equation, we get:
Hence, amount of iron produced is 101.36 grams.
