Answer:
A single compound reacts with itself.
Explanation:
Disproportionation is a chemical reaction,most times a redox reaction, in which a molecule is transformed into two or more dissimilar products. In a disproportionation reaction, the species are simultaneously oxidized and reduced to form at least two different products.
A typical example of a specie that disproportionate is the copper I ion as shown below;
2Cu^+(aq) ------> Cu(s) + Cu^2+(aq)
The two oxidation states of copper formed in the disproportionation are Cu(0) and copper (II).
Answer:
Q = 768.47 J
Explanation:
Given that,
Mass of the metal, m = 25 g
Initial temperature, T₁ = 21.0 ºC
Final temperature, T₂ = 80.0 ºC
The specific heat of the metal is 0.521 J/gºC.
We know that the heat released due to the change in temperature is given by :
Hence, 768.47 J of heat energy will be needed.
