These are electron dot diagrams.
They use dots arount the symbol of an atom to represent its <em>valence electron</em>s.
You will also see them called <em>Lewis dot symbols</em> or <em>Lewis diagrams</em>.
simple molecules contain two atom bonded together
Answer:
Magnesium atom, Mg is oxidized
Explanation:
This is because it loses electrons to form msgnesium ion.
No work , because the object was not pushed,pulled,dropped,or picked up
Answer:
All the statements are correct but "all chemical reactions can be classified as one of the five general types".
Explanation:
Hello,
In this case, I assume you are looking for the wrong statement as long as the following ones are correct and matches with the foundations of chemical reactions:
- The only way to determine the products of a reaction is to carry out the reaction. This is clear, because after the chemical reaction is done, one identifies the products.
- Complete combustion has occurred when all the carbon in the product is in the form of carbon dioxide. This is clear due to a 100% conversion.
- A single reactant is the identifying characteristic of a decomposition reaction. All decomposition reactions have only one reactant which breaks into less complex species.
So the wrong statement is:
- All chemical reactions can be classified as one of five general types. This is wrong because there are four widely known chemical reactions: synthesis, decomposition, simple displacement and double displacement.
Best regards.
