Answer:
The water is universal solvent because it is a polar molecule.This have hydrogen bonding in which hydrogen molecule have positive charge and oxygen molecule have negative charge because electro negativity of oxygen molecule is higher than hydrogen molecule that is why it pull the hydrogen molecule and formed a polar molecule.That is why is also known as universal solvent.
Answer: H₂SO₄ is the chemical formula that represents sulfuric acid.
Explanation:
1) H stands for hydrogen and H₂ means that each unit contains two atoms of hydrogen.
2) S stands for sulfur. Since there is not subscript, means each unit contains one atom of sulfur.
3) O stands for oxygen, and O₄ means that each unit has four oxygen atoms.
4) The way the compound is build up is the S atom at the center with two double bonds to each to one atom of O, and two single bonds one to each OH ion.
5) Sulfuric acid is a strong acid, so it dissociates in water and alghough the formula H₂SO₄ is used to represent it, the aqueous solution is formed by ions: HSO₃⁻, H⁺, SO₄²⁻, and OH⁻, as represented by these dissociation equaitons show:
1) H₂SO₄ ⇄H⁺ + HSO₄⁻ first dissociation
2) HSO₄⁻ ⇄ H⁺ + SO₄²⁻ second dissociation
So, H₂SO₄ is one form to represent sulfuric acid.
I am not the best at this, but im pretty sure its below cloud
Answer:
[Co(H2O)3(CO)3]3+
Explanation:
If an octahedral specie has the general formula EX3Y3, the X groups may be arranged to be on one face of the octahedron and the Y groups may also be arranged to be on the other face of the octahedron or lie in the plane of the central atom.
The two stereo isomers described above are called fac (facial) and mer (meridional) isomers.
Only [Co(H2O)3(CO)3]3+ can exhibit this type of isomerism among the options in the questions since it has the general formula, EX3Y3.
