Explanation:
For ICl²-, the central iodine atom is bonded to the 2 chlorine atoms and has 3 lone electron pairs.
Altogether it has 5 electron domains, which means it is sp3d hybridized. (C)
The density of crystal is 2.65 g / mL
we know that
Density = Mass / Volume
So volume occupied = Mass / density
Mass of crystal = 4.46 g
So volume occupied by crystal = 4.46 / 2.65 = 1.68 mL
As the graduated cylinder contains water upto 25.0 mL
So if we immerse the crystal in that cylinder the water level will rise to 25+1.68 = 26.68mL
so the new read will be 26. 68 mL
A cell is made of molecules and a molecule is made of atoms. That's the simplest way of putting it. More complicated is that a cell is made up of macromolecules, such as proteins, lipids, etc. A molecule is a particular configuration of atoms.
Periods go left to right or horizontally. Groups are a name for the vertical columns in a periodic table. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital.
