Answer:
672 g
Explanation:
We can calculate the mass of water that can be warmed from 25.0°C to 37.0°C by the addition of 8,064 calories using the following expression.
where,
c: specific heat of the water
m: mass
ΔT: change in the temperature
The mass of water that can be warmed under these conditions is 672 grams.
Answer:
Iron is being oxidized at the anode and water is acting as the electrolyte.
Explanation:
When iron is exposed to oxygen and water , the rusting of iron takes place.
<u>The reaction taking place at anode : Oxidation of iron.</u>
The reaction taking place at cathode : Reduction of oxygen in the air.
The overall reaction:
The rust that is hydrated iron(III) oxide can form iron(II) ions which can react further with oxygen.
Thus, from the above reactions ,
Iron is being oxidized at the anode and water is acting as the electrolyte.
