hydrogen
A2:Coal is the fuel that produces the least pollution among the choices. Hydrogen would be the least polluting except for the reality that hydrogen is produced by burning coal to produce electricity to electrolyse water. Only if the electricity used to produce the hydrogen were produced by hydro, wind or solar, would hydrogen be less polluting than coal.HYDROGEN

To answer this, we simply need to consider the lightest of the chemical elements, hydrogen. Hydrogen's atomic number, and thus its number of protons and electrons, is 1. So, by necessity, that is the minimum amount of valence electrons an atom can have.
e. there is a minimum temperature for hydrogen fusion.
Two, HCOOH the formic acid.
The temperature at which hydrogen fuses is 10,000,000 degrees Kelvin. This is the minimum temperature the core of a proto star has to have to become a true star.
Water pollution prevention and control measures are critical to improving water quality and reducing the need for costly wastewater and drinking water treatment. Water pollution can be controlled in the multiple ways. It is best controlled by the dilution of water.
