The balanced reaction is:
<span>2Al (s) + 3Fe(NO3)2 (aq) = 3Fe (s) + 2Al(NO3)3 (aq)
</span>
We are given the amount of <span>iron (II) nitrate solution with its purity. This will be the starting point of our calculation.
265 (.845) gram </span>iron (II) nitrate (1 mol Fe(NO3)2 / 179.85 g Fe(NO3)2) ( 3 mol Fe / 3 mol <span>Fe(NO3)2) (55.85 g Fe / 1 mol Fe) = 69.54 g Fe</span>
Answer:
Option a (100 kPa) is the appropriate option.
Explanation:
The given value is:
Original pressure,
P₁ = 50 kPa
Let the new pressure be "x".
Now,
⇒
On substituting the values, we get
⇒
On applying cross-multiplication, we get
⇒
⇒
Thus the answer above is the right one.
I believe it would be the transformation of electrical energy to heat energy, and the transformation of heat energy and then the heat to the bread
