Can the amount of radiant energy that shines out of a flashlight exceed the chemical energy stored in the batteries?

No.
That would be getting more energy out of something than what's been put in there in the first place. As far as we understand the universe, that just isn't possible.

How many volts does a flashlight need to make it work?
The answer is governed by the size of the flashlight. Count the amount of batteries that go into the flashlight and then multiply by 1.5 and this will give you the voltage of the flashlight. For NiCd and NiMH rechargeable batteries multiply by 1.3 volts.
How does the amount of energy in the batteries compare to the total amount of light given off by the flashlight?
Well more chemical energy in a battery means more energy can be converted to light energy. I believe that the light will last longen and\or be brighter.
How does the amount of energy in batteries in a flashlight compare to the total amount of energy given off byt the flashlight as light and heat?
All of the energy in the battery, or most of it, is eventually given off as heat and light.
Why do telephone batteries not cell phone batteries get hot?
Telephone batteries commonly get hot because they are a form of lithium batteries. All batteries contain chemical reactions within them that produce some amount of heat, it is just that lithium batteries produce great amounts of it.
Are there any battery powered lamps?
You bet! It's called a flashlight, too. Some camping lamps use fluorescent bulbs and batteries to emit about the same amount of light.
Examples of the thing that can be transformed from one another but the total amount of energy never changes?
Flashlight = chemical energy(battery) - electrical energy
What happens to the amount of the sun's mass as it burns?
It converts into radiant energy
What is good thing and bad things about radiant energy?
Radiant energy is very cheap and creates the same amount of electricity as other resources. Yet radiant energy can harm skin and cause skin cancer.
Why do batteries fail?
Batteries only have a certain amount of power, once this is gone the battery is then useless. This is of course untrue with rechargeable batteries.

What determines the amount of radiant energy that can be carried by an electro magnetic wave?
i believe the frequency
How do you explain the effect of the number of batteries on the amount of current produced?
The number of batteries has only an effect on the amount of current when they are equivalent and connected in parallel. The amount of current that can flow from a group of batteries connected in series is limited to the current provided by the battery that produces the lowest current flow in the string.
