Sodium tetradecyl sulfate এর কাজ, ব্যবহারের নিয়ম

The colour of both barium chloride and sodium sulphate is white.

Solution: From formula Mass % of an element = Molar mass of component/Molar mass of compound ×100 The molecular formula of compound (Na2SO4) is  = [(2 × 22.99) + (32.06) + 4 (16.00)] =...

Answer: Given that 0.375 Molar aqueous solution Molar represent molarity of the solution Hence given molarity of solution will 0.375M Formula of molarity Molarity (M) = No. of moles of solute / volume of solution in...

(a) Platinum, gold, and silver are used to make jewellery because they are very lustrous. Also, they are very less reactive and do not corrode easily. (b) Sodium, potassium, and lithium...

Metals such as potassium and sodium react so vigorously that they catch fire if kept in the open. Hence, to protect them and to prevent accidental fires, they are kept...

(a) Yes. The atoms of all the three elements lithium, sodium, and potassium have one electron in their outermost shells. (b) Both helium (He) and neon (Ne) have filled outermost shells....

Na atom get oxidize and Cl is reduced

(i) Sodium oxide                 → Na2O  (ii) Aluminium chloride       → AlCl3  (iii) Sodium suphide           → Na2S  (iv) Magnesium hydroxide → Mg(OH)2

A sodium atom and ion, differ by one electron. For 100 moles each of sodium atoms and ions there would be a difference of 100 moles of electrons.  Mass of 100...
