Nonmetals have the ability to attract electrons better than metals because they have a higher electron affinity or electronegativity than metals.
<h3>What is electronegativity?</h3>
Electronegativity is the tendency, or a measure of the ability, of an atom or molecule to attract electrons and thus form bonds.
An element in the periodic table with a high electronegativity will automatically have a high electron affinity.
Metals (low electronegativity) are known to lose electrons to non-metals (high electronegativity), hence, nonmetals have the ability to attract electrons better than metals because they have a higher electron affinity or electronegativity than metals.

Answer:
3.018 x 10⁻⁶ M.
Explanation:
- Co(OH)₂ dissociates in solution according to the equation:
<em>Co(OH)₂ → Co²⁺ + 2OH⁻.</em>
∵ Ksp = [Co²⁺][OH⁻]² = (s)(2s)² = 4s³.
∴ 4s³ = 1.10 x 10⁻¹⁶.
∴ s³ = 1.10 x 10⁻¹⁶/4 = 2.75 x 10⁻¹⁷.
<em>∴ s</em> = ∛(2.75 x 10⁻¹⁷) = <em>3.018 x 10⁻⁶ M.</em>
The Yellow River is the most important water resource for the dry north of China, playing an irreplaceable role in economic development, and agriculture. Since 1960 over 14 dams have been constructed on the river for hydroelectric power, which is vital to northern China's infrastructure.
CO+2 H2=CH3OH
2.85 mol Co x (2mol H2/1 mol Co)=5.70 mol just concert to grams
5.70 mol H2 x (2 g H2/1 mol H2) =11.40 grams of H2
