Answer:
None
Explanation:
Methylene is an organic compound and organic compounds consist of hydrogen atoms and Carbon atoms in n this case Methylene(CH2) has one carbon and two hydrogens .
Answer: An element's group number tells you how many valence electrons the element has.
Explanation:
In the periodic table, each element is placed in a specific location because of its atomic structure.
The elements are arranged in rows, called a period. All of the elements in a period have the same number of atomic orbitals.
The elements are also arranged in vertical columns. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. These electrons are called as valence electrons. Example: Group 1 elements have 1 valence electron each.
One example could be scanners linked to a networked database. Those little hand scanners that you see at a Publix or Wal-Mart report back to series of systems that allow stores to track inventory across the entire business allowing them to anticipate when they should order more of one item or see what has been selling particularly well -- or not. Consumers don't see any of that when they buy their Count Chocula, but the database systems do and those can be extremely complex. I hope this helps you out!! have a wonerful day!!

Answer:
See explanation
Explanation:
When the complex ion Co(H2O)6 2+(aq) is placed in solution and chloride ions are added, the following equilobrium is set up;
Co(H2O)62+(aq) + 4 Cl-(aq) <=> CoCl42-(aq) + 6 H2O(g)
Co(H2O)6 2+(aq) solution is pink in colour while CoCl42-(aq) solution is blue in colour.
Since the solubility of CoCl42-(aq) is endothermic, heating the solution will move the equilibrium position towards the right (more CoCl42-(aq) is formed and the solution is blue in colour).
When the solution is cooled, more Co(H2O)62+(aq) is formed and the equilibrium position shifts towards the left and the solution becomes pink in colour.
