Let X be a compactum such that dimℚX ≤ n, n ≥ 2. We prove that there is a ℚ–acyclic resolution r: Z→X from a compactum Z of dim ≤ n. This allows us to give a complete description of all the cases when for a compactum X and an abelian group G such that dimGX ≤ n, n ≥ 2 there is a G–acyclic resolution r: Z→X from a compactum Z of dim ≤ n.
