A redox reaction be used as a source of electrical energy only when two half-reactions are physically separated. <span>The electrons that are released at the anode flow through the wire, producing an electric current. Galvanic cells therefore transform chemical energy into electrical energy that can then be used to do work.</span>
Answer:
Acceleration
Explanation:
The rate at which velocity changes with time is called Acceleration is a measure of how quickly the velocity is changing. If velocity does not change, there is no acceleration.
Answer: 3.45 L carbon dioxide are produced
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 
of particles.
To calculate the moles, we use the equation:
According to stoichiometry :
5 moles of 
produce = 3 moles of 
Thus 0.257 moles of will produce=
of
Volume of 
Thus 3.45 L carbon dioxide are produced
<em>Answer:</em>
<em>Ether:</em>
Ether are organic compounds that contain ether functional group , in which oxygen atom is connected with two alkyl or aryl group.
They have general formula as follow
- R---O---R or R'---O----R or R'---O---R'
while R = Alkyl
R' = Aryl
It is not a pure substance, because a solution are mixed chemicals in a way that the molecules are not bonded with one another. Thus, separating them from compounds and elements, which are pure substances.
