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.
It would be CH2! you’re just simplifying C4H8, 4 can go into C4 1 time (so we just say C) and 4 can go into H8 2 times (H2)
Answer:
The charge of cobalt in the salt is + 2.
Explanation:
The charge of the salt = 0 . This is because it is neutral.
Charge of cobalt = ?
Charge of oxygen = -2 (This is a constant value, it is -2 only in peroxides)
Charge of salt = Charge of cobalt + Charge of oxygen
0 = x + (-2)
x = + 2
The charge of cobalt in the salt is + 2.
A catalyst increases the rate of a chemical reaction, as a sub category, an enzyme also preforms the same job.
