Answer:
BaCl₂ and H₂SO₄
Explanation:
The reaction is the precipitation of BaSO₄ from solution.
This means that our reactants must contain the Ba ion and SO₄²⁻ ion. The reactants that meet this criteria are the; BaCl₂ aand H₂SO₄
The reaction is given as;
BaCl₂ + H₂SO₄ --> BaSO₄ + 2HCl
Answer:
We can see the bright matter, like stars, but we know some other matter is there(dark matter)because of how it pulls on the bright matter.
Explanation:
Reacting nitrous acid with aromatic amines to produce diazonium salt is one of the most used processes. An aromatic amine called aniline reacts with nitrous acid to generate benzene diazonium chloride, a diazonium salt.
To create azo colors, benzene diazonium chloride combines with phenol, -napthol, aniline, and 2-methylaniline. These reactions result in the removal of an HCl molecule. Red organic dye is created when benzene and benzene diazonium chloride interact. Since the solutions created in this method do not last, the reactions involving a diazonium salt are always carried out with a freshly prepared solution. Diazonium salts are very flammable when they are solid because of their instability.
