No Rain water is very soft. The harness of water is a result of the mineral content and rain water has a very low mineral content as it hits the ground or water on the ground.
mineral water
Mineral water, rain water's acidity has drastically increased over the past couple of decades and is less pure than it used to be.
Sort of. Mineral water is non an electrolyte itself, but it contains electrolytes.
Cytoplasm
Water contains one oxygen and two hydrogen atoms connected by covalent bonds. 90 percent is hydrogen, plants likes it , mineral and gases can interact with the falling rain water droop during its way down truth the atmosphere, it can get whatever the dust in the air could have, as carbon, nitrogen, potash, pesticide, algae ,bacteria, it depends on the weather conditions and area, if it rain in a no contaminated area where usually rains it will have basically nitrogen and a trace of co2 in that rain water...

Most of the Earth's water contains salt because over millions of years, rain and rivers have washed mineral salts from rocks into the oceans. As water evaporates from the oceans, the salt remains behind, leading to an accumulation of salt in the ocean water. This is why most of Earth's water, especially in the oceans, contains salt.
Mineral water is rain water that fell as distilled water, then drained into the ground where it dissolved out some of the minerals that are in the rocks. i.e. it became "mineralised" or polluted by, or contaminated by the ground minerals present in that area which can include poisons such as arsnic and cadmium. All bottelled mineral water should be checked for toxicity, read the label. You cannot beat rain water for drinking.
Rain water is mixture, it is not a pure compound but contains dissolved gases and somtimes particulate matter.
No. A pure substance describes one that contains only one type of element/molecule. Mineral water is a mixture, since it contains many different types of minerals, next to water, and can therefore not be called a "pure" substance.
No. Mineral water is just that, mineral water. It contains various minerals that can be beneficial to your health. Simply adding cO2 will just give you bubbly tap water.
