Answer:
an intrinsic characteristic of a particular acid, not related to concentration
Explanation:
this is easy
Answer: d
Explanation:
Earth is larger than the moon, so Earth pulls on the moon
Hydrochloric acid and sodium hydroxide neutralise each other and the pH resulting solution will be 7.
33 - 15 = 18
This element is P-33
Answer:
of different elements with different electronegativities
Explanation:
A molecule containing two atoms "of different elements with different electronegativities"
A polar covalent bond exists when two different atoms (non-metals) with different electronegativities are able to share their electrons in a covalent bond.
Some examples of polar covalent bonds are seen in:
1. Ammonia(NH3): The polar covalent bonds exists between the nitrogen and hydrogen atoms.
2. Water(H2O): The polar covalent bond exists between hydrogen and oxygen. The oxygen molecule has a net negative charge while the hydrogen atoms have a net positive charge.
