Yes
Covalent
AnswerPolar. Its geometry is bent, as it has one lone pair (nonbonding domain) and two bonding domains. It has an asymmetrical distribution of charge. However, it is not very polar as the electronegativities of sulfur and oxygen are similar.
The chemical formula of aluminium sulfite is Al2(SO3)3.
What is the electronegativity and hardness of SO3
Formula: SO3
SO3 is the chemical formula for sulfur trioxide.
SO3 is a non polar molecule. Although the bonds between the S and O atoms are polar because S is more electronegative than O hence creating an electronegativity difference, the molecule is non polar. This is because the negative and positive centres are both loacted in the same place (at the S molecule) as they are all on the same plane and therefore there is no permanant dipole as the dipoles in the bond cancel each other out, therefore the molecule is non polar.
Al+3 SO3+2 <---- these are the ions and their charges Al+3 Al+3 SO3+2 SO3+2 SO3+2 <---- the charges have to add up to zero, so two +3 aluminum ions cancel out three +2 sulfite ions. Al2(SO3)3 <--- simplify
3 and SO3 is an anion with a +1 charge
SO3 is sulfur trioxide.
Cr+6 SO3-2 ------> these are the ions and their chargesCr+6 SO3-2 SO3-2 SO3-2 ----> the charges have to add up to zero, so three +2 sulfite ions cancels out one +6 Cr ion.Cr(SO3)3 ----> simplify
The balanced equation for the reaction between SO3 and H2O is: SO3 + H2O → H2SO4
