Why is plastic a harm to the environment? what is a way to dispose of plastic?
Plastic is a harm to the environment because it does not degrade so it remains there forever and harms the soil. It gives an unpleasant gas that can cause air pollution.
One way to dispose of plastic is simply to recycle it.
what is the equation of the reaction of steam?
Metal+steam- metal oxide + hydrogen
