Answer:
Calcium becomes an ion with a charge of 2+
Oxygen becomes an ion with a charge of -2
Explanation:
since calcium lost two electrons, it has 20protrons, but only 18 electrons. this makes calcium a positive ion with a charge of 2+
An oxygen molecule consists of two oxygen atoms that have a double bond between each other and share valence electrons. the oxygen ion is formed when the atom of oxygen gains two valence electrons. this results in an oxygen ion with a charge of -2
Answer:
C) The Environment
Explanation:
This is because fossil fuels are carbon based and when burnt release that carbon store in the form of Carbon Dioxide and other gasses. These gasses such as carbon dioxide contribute to factors such as global warming, this is due to the enhanced greenhouse effect. The enhanced greenhouse effect is when the buildup of these gasses gets too high that it causes heat to build up. This happens because heat reflected and given off from the surface cannot escape are atmosphere and is reflected back.
