Pollution is the introduction of contaminants into the natural
environment that cause adverse change. Pollution can take the form of
chemical substances or energy, such as noise, heat or light. Pollutants,
the components of pollution, can be either foreign substances/energies
or naturally occurring contaminants. Pollution is often classed as point
source or nonpoint source pollution.
Hope this helps :p
The correct answer would be letter B: water molecules split into oxygen and hydrogen atoms. This is how plants convert water into a usable source of food and energy to support its photosynthetic capacity to power the plant within its environment.
I would think the closest answer is just that there is to much weight on it at a time or to much weight in just one portion of the bridge. That or its weakly built.
Answer:
Potassium = Great conductor of heat and electricity
Neon = Non reactive
Boron = has properties of both metals and non metals
Barium = Malleable and highly reactive
Explanation:
Potassium = Great conductor of heat and electricity
Potassium is soft metal and has low melting point. It is white silvery luster with great heat conducting properties.
Neon = Non reactive
Neon is present in group eighteen. It is noble gas. Its outer electronic shell is completely filled that's why it is non reactive.
Boron = has properties of both metals and non metals
Boron is metalloid and behave like both metals and non metals.
Barium = Malleable and highly reactive
Barium is belong to group 2A. It is alkaline earth metal. It is highly reactive towards other elements such as oxygen, fluorine, chlorine , etc.
