Describe where a hydrogen bond can form among water molecules.
1 answer:
Answer:
In water hydrogen bonding formed between partially negative oxygen and partially positive hydrogen atoms.
Explanation:
Hydrogen bond is a partially electrostatic attraction between hydrogen (H), which is bonded to a more electronegative atom such as nitrogen (N), oxygen (O) or fluorine (F), and another adjacent atom bearing a lone pair of electrons.
In water molecule hydrogen and oxygen have difference in electronegativity, due to which dipoles are form. One is partial positive on hydrogen atom and other is partial negative on oxygen atom. The electrostatic attraction occur between two oppositely charged poles which is known as hydrogen bonding.

Answer:- 2.4 mol .
Solution:- It asks to calculate the moles of formed when 1.2 moles of
are reacted.
There is 2:4 mol ratio between and
. So, the moles of reactant are multiplied by the mol ratio to get the moles of
. The calculations are shown below:
= 2.4 mol
So, 2.4 moles of are formed when 1.2 moles of
were reacted.
