Yes. A well made piano can have a useful lifetime of hundreds of years if it is well cared for and does not undergo severe environmental stress.
It will burn out eventually, but that will be very far from now, not in our lifetime.

they need sun,water,and carbon dioxide
It will have a shorter lifetime. The Sun should last about 10 times longer.
The sun should not become a black hole. It does not have sufficient mass to undergo the necessary collapse.
They react with acids in order to undergo neutralization.
No. The less massive a star, the longer it will last. A main sequence star half the mass of the sun can be expected to last about 5 times longer.
hydrogen mainly, but there undergo fission to form helium (which undergo fission as the star approaches supernova producing the heavy elements like carbon)
sublimation
Yes, plants need sunlight to undergo photosynthesis and grow.
