metal have free electrons in their outer shell which make them generally good conductors of electricity. Example is the copper which is used for electrical wiring since is a good conductor of electricity. copper with electronic configuration of (Ar)4s2 has two free electrons in their outer most shell which allow it to conduct electricity.
Combustion of fossil fuels
Explanation:
The most likely source of the carbon dioxide shown in the graph is the combustion of fossil fuels for both industrial and domestic use.
- Fossil fuels are hydrocarbon units.
- They burn in the presence of oxygen gas to from carbon dioxide and water.
- The level of carbon dioxide has been increasing dramatically with increase in industrialization.
- The fuels are used and needed for the workings of machinery.
- Domestically they are used in heating homes and powering automobiles.
- These processes produce carbon dioxide as a waste product.

<h3>the balanced chemical reaction would be :</h3>
CH4 + 2O2 =》CO2 + 2H2O
Answer:
the balanced chemical reaction is provided above .
Explanation:
the given reaction is reaction of methane with oxygen ( or burning of methane in presence of oxygen )
it is highly exothermic, because high amount of heat is evolved in this reaction
First, it combines with carbon dioxide in the soil to form a weak acid called carbonic acid. ... Carbonic acid slowly dissolves away minerals in rock, especially the carbonate minerals that make up limestone and marble. The weak acid decomposes the insoluble rock into watersoluble products that move into the groundwater.
