Answer: In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.
Explanation:
Carbohydrate atoms usually have how hydrogen atoms as compared to oxygen atoms
Answer:
B because if it's adding more atoms but becoming more compact then it is getting smaller.
Explanation:
Answer: In the reaction , acts as a base because it has accepted a hydrogen ion or proton.
Explanation:
According to Arrhenius, species which dissociate to give hydrogen ions when dissolved in a solvent like water are called acid.
A species which readily accepts a hydrogen ion or proton is called a base.
For example,
Here, is donating hydrogen ion. So, it is an acid whereas is accepting the hydrogen ion. Hence, is a base.
Thus, we can conclude that in the reaction , acts as a base because it has accepted a hydrogen ion or proton.
