When paper burns, it releases two distinct forms of energy
Thermal Energy
Light Energy
Thermal Energy is heat energy, heat energy is formed from the flame on the paper, in this scenario.
Light energy comes from the reaction of the paper, the flame.
In conclusion, both energy's form from the reaction of the paper, and the combustion in the air. Thus, heat and light.
Idk why are they important?
Answer:
H2O2
Explanation:
it is made up of Oxygen and Hydrogen. Unlike water which is H2O Hydrogen peroxide is made up of 2 oxygen atoms
Answer:
Answer is given below.
Explanation:
Anode is that electrode where oxidation occurs. Cathode is that electrode where reduction occurs.
In cell representation, half cell present left to salt-bridge notation
is anodic system and another half cell present right to salt-bridge notation
is cathodic system.
So anode is Cu and cathode is Ag.
oxidation: ![Cu-2e^{-}\rightarrow Cu^{2+}(aq.)](https://tex.z-dn.net/?f=Cu-2e%5E%7B-%7D%5Crightarrow%20Cu%5E%7B2%2B%7D%28aq.%29)
[reduction:
]![\times 2](https://tex.z-dn.net/?f=%5Ctimes%202)
-----------------------------------------------------------------------------------------------
chemical equation: ![Cu+2Ag^{+}(aq.)\rightarrow Cu^{2+}(aq.)+2Ag](https://tex.z-dn.net/?f=Cu%2B2Ag%5E%7B%2B%7D%28aq.%29%5Crightarrow%20Cu%5E%7B2%2B%7D%28aq.%29%2B2Ag)
Oxidizing agent is that species which takes electron from another species. Here
takes electron from Cu. Hence
is the oxidizing agent.
Reducing agent is that species which gives electron to another species. Here Cu gives electron to
. Hence Cu is the reducing agent.
Answer:
C
Explanation:
add them together and multiply by 2
