Answer:
b. oxygen side being slightly negative and the hydrogen side being slightly positive.
Explanation:
The water molecule is a polar molecule, that is to say that its distribution of electronic density is different throughout the molecule.
In this way, in the water molecule there is a negative partial charge towards the oxygen atom and a positive partial charge towards the hydrogen atom.
This polar characteristic of the water molecule allows ions and other molecules to exhibit water solubility and is widely used in chemical reactions.
Answer:
3
Explanation:
This is the answer because when it is full moon the tides are higher.
Always remember that a compound can be separated into simpler substances by chemical methods/reactions. While elements cannot be broken down into simpler substances by chemical reactions. You can do a flame test and spectrum analysis to determine whether a solid material is an element or a compound. Check the boiling and/or melting point, color or density. Also check the solid material’s reaction with oxygen, hydrogen, calcium, or various acids. Examine and study its physical chemistry. The element(s) that may be present may be identified by checking the absorption edges from an x-ray spectrum.
