I am not sure but I believe it is B. Precipitation because the definition is: <span>the action or process of precipitating a substance from a solution ^-^ Hope this helps</span>
I'm sure nothing would happen.
The coefficient for Fe will be 6, because the left side Fr equals 6.
A volcano is a conical hill or mountain that ejects hot ash and lava in an eruption. In addition to hot ash a lava volcanoes erupt many gases. The most common gases erupted by a volcano are carbon dioxide, sulfur oxides and water vapor. Carbon dioxide is common in volcanic eruptions as it is formed mainly when subducting plates laden with the calcium carbonate skeletons of tiny marine organisms. Once the plate melts the carbon dioxide is incorporated into magma.
