Question

Balance the following chemical equation Name the type of reaction also
1) Reaction between barium chloride and sodium sulphate solution to give
barium sulphate and sodium chloride
ii) Magnesium reacts with oxygen gas to form magnesium oxide
iii) Sodium hydroxide reacts with sulphuric acid to form sodium sulphate
and water​

Answer 1

Answer:

Answer

Explanation:

1..When the solutions of sodium sulphate and barium chloride are mixed a white precipitate is formed which is insoluble in HCl. ... When sodium sulphate chemically reacts with barium chloride in the form of their aqueous solutions, white precipitate of barium sulphate appears.

2..When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide, which is a compound. ... After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction.

3..The balanced equation for the reaction of H2SO4 and sodium hydroxide that produces sodium sulfate and water is H2SO4 + 2(NaOH) -----> Na2SO4 + 2(H2O).
