2al(oh)₃ + 3h₂so₄ → al₂(so₄)₃ + 6h₂o\nhow many oxygen atoms are on the left side of the equation?\na. 18\nb. 5\nc. 12\nd. 6
Answer
Explanation:
Step1: Calculate oxygen atoms in (2Al(OH)_3)
In (Al(OH)_3), there are (3) oxygen atoms. With a coefficient of (2), the number of oxygen atoms is (2\times3 = 6).
Step2: Calculate oxygen atoms in (3H_2SO_4)
In (H_2SO_4), there are (4) oxygen atoms. With a coefficient of (3), the number of oxygen atoms is (3\times4=12).
Step3: Sum the oxygen atoms
Add the oxygen atoms from both compounds: (6 + 12=18).
