There are 1.2044 × 10²⁴ molecules in 2 moles of water.
Explanation:
Given: 2 moles of water.
To convert moles of water into molecules by multiplying the number of moles by Avogadro's number (6.022 × 10²³ molecules).
We have to find the number of molecules as,
Number of molecules = Moles × Avogadro's number
Plugin the values as,
Number of molecules = 2 × 6.022 × 10²³ molecules
= 1.2044 × 10²⁴ molecules.
So there are 1.2044 × 10²⁴ molecules in 2 moles of water.
Answer:
The larger electronegative oxygen atom strips the electron from one of its hydrogen atoms, leaving the proton to dissociate.
Explanation:
Water is a molecule composed of hydrogen and oxygen atoms that forms a covalent bond i.e. share electrons. However, due to the fact that the oxygen atom in a water molecule is more electronegative than the hydrogen molecule, it tends to draw electrons towards itself, leaving the hydrogen atom more positive. This causes the POLARITY of water.
To ionize means for the atoms of a compound to dissociate into electrically charged ions (positive and negative) in an aqeous solution. Water is able to ionize because the more electronegative oxygen atom draws the electron from one of its hydrogen atoms, leaving the proton (H+) to dissociate.
There doesn't seem to be a clear answer, it is placed in the center when it's substances is on the corners it doesn't give anything else
Mercury expands when it is heated. This process is called thermal expansion.
Answer:
How the relative density of a substance is related to the density calculate the density of iron if its relative density is 2 and a density of water is 2gcm -3
R.d= relative density of substance/ relative density of water
R.d= 2/2
R.d= 1gcm-3
