the answer is heat. while a car is in idol, the tailpipe gets very hot, (motorcycle, car, etc.) this also produces h20 which you can see dripping out of the tailpipe.
Answer: The standard free energy change for a reaction in an electrolytic cell is always positive.
Explanation:
Electrolytic cells use electric currents to drive a non-spontaneous reaction forward.
Relation of standard free energy change and emf of cell
where,
= standard free energy change
n= no of electrons gained or lost
F= faraday's constant
= standard emf
= standard emf = -ve , for non spontaneous reaction
Thus 
Thus standard free energy change for a reaction in an electrolytic cell is always positive.
Answer:
In general an acid reacts with a carbonate or hydrogen-carbonate to produce a salt, carbon dioxide gas and water.
Answer:
Germanium.
Explanation:
In a neutral atom: the number of protons = the number of electrons.
Atomic number of a neutral atom = number of electrons = number of protons.
- Phosphorous is an element with atomic number 15 and thus contains 15 electrons and 15 protons.
- Cobalt is an element with atomic number 27 and thus contains 27 electrons and 27 protons.
- <em>Germanium is an element with atomic number 32 and thus contains 32 electrons and 32 protons.</em>
<em></em>
- Sulfur is an element with atomic number 16 and thus contains 16 electrons and 16 protons.
