Hello!
In this case, since the calculation of the required energy is performed via the following equation:
Thus, since the mass is 14 g, specific heat is 4.184 J(g*°C) and the temperatures are 47 °C and 18 °C respectively, the resulting energy is:
Best regards!
Answer:
it gets reduced from a +3 oxidation to a 0.
Explanation:
the decomposition of iron oxide to elemenTal can be represented by the following equation: iron oxide (Fe203), the oxidation state of iron is +3 while that of oxygen is -2. therefore, the above reaction is a redox (reduction oxidation reaction)
