(i) Oxidation It is a process in which a substance gains oxygen, e.g. Ans.3BaCl 2 (aq) + Al 2 (SO 4 ) 3 (aq) -> 2AICI 3 (aq) + 3BaSO 4 (s) (d)Potassium metal reacts with water to give potassium hydrogen oxide and hydrogen gas. Name this gas. Q.1 Which of the statements about the Reaction below are incorrect ? Source(s): https://shorte.im/a8u5l. The question given to us is, Barium chloride + Aluminium sulphate → Barium sulphate + Aluminium chloride. occurring in water: Potassium sulfate and. Ans. Give examples. So we mix stoichiometric barium chloride and potassium sulfate: #BaCl_2(aq) + K_2SO_4(aq) rarr BaSO_4(s)darr + 2KCl(aq)#. Q8. As an inexpensive, soluble salt of barium, Barium Chloride finds wide application in the laboratory. [ Check the balance ] Barium chloride react with potassium sulfate to produce barium sulfate and potassium chloride. Ans. 2KBr (aq) + BaI2 (aq) –> 2KI (aq) + BaBr2 (aq). chloride and barium sulfate. Hence , the number of atoms of each element on the two sides of the equation are equal is called a balanced equation. (ii).Write the reaction of the substance ‘X’ named in (i) above with water. Thus, Copper Sulphate reacts to form iron (ii) Sulphate, the blue colour of copper sulphate Solution fades. (i) Solution of barium chloride and Sodium sulphate in water react to give insoluble barium sulphate and the solution of sodium chloride. (b) Chlorine gas and iron hydroxide are produced. Write one equation each for decomposition reactions where energy is supplied in the form of heat, light and electricity. This hinders the burning of magnesium. Therefore, food items like potato chips etc., are packed with nitrogen gas to prevent them from rancidity for a. Q20. Find another reaction.

(b) Hydrogen sulphide gas burns in air to give water and sulphur dioxide.. Ans. The chemical formula is CaO. (i).Name the substance ‘X’ and write its formula. What do you mean by precipitation reactions? Ans.3BaCl 2 (aq) + Al 2 (SO 4 ) 3 (aq) -> 2AICI 3 (aq) + 3BaSO 4 (s) (d)Potassium metal reacts with water to give potassium hydrogen oxide and hydrogen gas. Ans. Why are decomposition reactions called the opposite of combination reactions? How do you find the concentration of a solution in ppm? 0 0. (a) Potassium bromide (aq) + Barium iodide (aq) -> Potassium iodide (aq) + Barium bromide (s), Ans. We would expect them to undergo a double displacement reaction with each other. 1 mole of barium chloride and 1 mole of potassium sulfate. What is a balanced chemical equation? Explain with suitable examples. Q11. What is the weight per volume method to calculate concentration? (d) Barium chloride + Potassium sulphate ->  Barium Sulphate + Potassium chloride. The representation of a chemical reaction by using the symbols and formulae of the reactants and the products is called a chemical equation. Why is a copper vessel covered with a green coating in rainy season ? The balanced chemical equation is Al2(SO4)3 + 3BaCl2 ----- … In the presence of enzymes as catalyst in our body , starch decomposes into simple sugars whereas proteins decomposes to form simpler molecules called amino acids. Are both ionic compounds in water react to produce barium sulfate and potassium are.
