If the density is higher than water than the object will sink
Answer:Cell reaction is going forward.
Explanation:
For any chemical reaction to be spontaneous or to move in forward direction the ΔG ,the Gibbs free energy must be negative.
The cell potential of a battery is positive for a spontaneous reaction, so for a battery to give output its cell potential must be positive.
Thermodynamics and electro-chemistry are related in the following manner:
ΔG=-nFE
n=number of electrons involved
F=Faradays constant
E=cell pottential of battery
so from the above equation ΔG would only be negative when E cell that is the cell potential is positive.
For a battery which is being used its cell potential is positive and hence the ΔG would be negative. So the cell reaction occurring would be in forward direction as ΔG is negative.
when the cell potential Ecell is 0 then ΔG is also zero then the reaction occurring in battery would be at equilibrium.
When the cell potential Ecell is - then ΔG is positive and the reaction would be occurring backwards.
Explanation:
Number of oxygen molecules = 10 billion = 
Number of hydrogen molecules = 10 billion = 
Number of molecules of hydrogen peroxides = 10 billion = 
Moles of oxygen gas :

Moles of hydrogen gas :


Moles of hydrogen gas :


Number of moles in hydrogen gas, oxygen gas and hydrogen peroxide is same.
Total number of atoms in
molecules of oxygen:
(2 atoms in 1 molecule)
Total number of atoms in
molecules of hydroegn :
(2 atoms in 1 molecule)
Total number of atoms in
molecules of hydrogen peroxide:
(4 atoms in 1 molecule)
Number of oxygen atoms and number of hydrogen atoms are equal but individually they are not equal to number of atoms in hydrogen peroxide.
