Question

Translate the following statements into chemical equations and then balance them.
a) Potassium metal reacts with water to give potassium hydroxide and hydrogen gas.
b) Zinc reacts with silver nitrate to give zinc nitrate and silver.
c) Hydrogen sulphide gas burns in air to give water and sulphur dioxide

plz solve Emergency !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
only right ans will be marked as brainlyest

Answer 1

Answer:

a) Potassium metal reacts very rapidly with water to form a colourless solution of potassium hydroxide (KOH) and hydrogen gas (H2).

b) This single replacement reaction will produce silver metal, Ag , and aqueous zinc nitrate, Zn(NO3)2 . Zinc is above silver is the metal reactivity series, so it will replace silver in silver nitrate. Notice that this is also a redox reaction.

c) N-atoms 2 2 H-atoms 6 6 Hence, the equation is balanced. (b) To translate the given statement into chemical equation The word equation for the given statement will be : Hydrogen sulphide + Oxygen → Water + Sulphur dioxide Step I. Writing the skeletal chemical equation H2S + O2 → H2O + SO2 Step II.
