Depends have you been taught that batteries store chemical energy then it’s chemical to light
Answer : The mass of oxygen will be, 36.8 grams
Solution : Given,
Moles of water = 2.30 moles
Molar mass of
= 32 g/mole
First we have to calculate the moles of oxygen.
The balanced chemical reaction will be,

From the balanced reaction we conclude that
2 moles of water decomposes to give 1 mole of 
2.30 moles of water decomposes to give
moles of 
Now we have to calculate the mass of oxygen.


Therefore, the mass of oxygen will be, 36.8 grams
Answer:
When light passes from one transparent medium to another, the rays are bent toward the surface normal if the speed of light is smaller in the second medium than in the first. The rays are bent away from this normal if the speed of light in the second medium is greater than in the first.
