Question
which gas is released when zinc granules are reacted with dil. sulphuric acid1 point(a)hydrogen gas(b)sulphur dioxide(c)zinc sulphate(d)hydrogen sulphide
Solution
When zinc granules are reacted with dilute sulphuric acid, the following steps can be followed to determine which gas is released:
-
Write down the chemical equation for the reaction between zinc and dilute sulphuric acid: Zn + H2SO4 → ZnSO4 + H2
-
Analyze the equation to identify the gas that is released. In this case, the gas is represented by the formula H2.
-
Identify the gas based on its formula. In this case, the gas with the formula H2 is hydrogen gas.
Therefore, the gas released when zinc granules are reacted with dilute sulphuric acid is hydrogen gas.
