Answer:
B. H2SO4 + BaCl 2 --------> BaSO4 + 2HCl
Explanation:
Neutralization reactions are characterized by their reactants of acids and bases reacting to form salt and water. All of the options except B, have formation of salt and water. Also, B is more likely a percipitation reaction (also a double displacement reaction) and not neutralization.
Molecular weight of HBr = 80.91 g/mol.
We know that, 1 mole of HBr = 80.91 g/mol
Therefore, 2 mole of HBr = 80.91 x 2
= 161.82 g.
Hence, 161.82 g of HBr should be dissolved in 1 liter solution, to obtain 2 M solution.
Answer:
The energy of the electromagnetic waves and gravitational radiation is a radiant energy. Radiant energy can travel through air, liquid, glass, space, or any other substance. It is created by changing configuration of electrons. Radiant energy can be transmitted in a vacuum environment, so the matter is not essential in transmitting radiant energy.
