<span>The overall reaction is as follows:
H2O2 + 2ClO2 => 2ClO2- + O2 + 2H+
Half cell reactions:
</span><span>ClO2 + e- => ClO2-
</span><span>H2O2 => O2 + 2H+ + 2e- </span>
(J) unit joule is the standard unit of heat (energy)
I think the answer is answer number 2. because in Daltons atomic theory you cannot have an element that magically appears out of no where and the same that goes into it the same should be equivalent that comes out. I hope that helps?
Answer:
The 35-watt light bulb does a work of 46200 joules in 1320 seconds.
Explanation:
From Physics we remember the definition of work (), measured in joules, by the following integral equation:
(1)
Where is the power, measured in watts.
If the power is stable in time, then the work can be calculated by the following algebraic equation:
(2)
If we know that and , then the work done by the 35-light bulb is:
The 35-watt light bulb does a work of 46200 joules in 1320 seconds.
