Answer:
Explanation:
Iso-electronic species have same number of electrons . Positive charged ions will have smaller size . As electrons add , size increases due to electronic repulsion .
Following species are isoelectronic .
Al³⁺ < Mg²⁺ < Na¹⁺ < Ne < F⁻¹ < O⁻² < N⁻³
Your answer is B.
Because it says that that carbon burns in presence of oxygen (C+O) which is equal ( => ) to Carbon Dioxide (
)
Also give you a 10, the last one looks really nice
<span>1 mol mag acetate dissociates into 1 mol Mg ion and 2 mols acetate ions in water. Therefore, if 0.6 mol mg of acetate is dissolved in 0.135 literss of water, we will have 0.6/0.135 = 4.44 moles / lit Mg2+ ions and 0.6*2/0.135 = 8.88 moles / liter C2H3O2- ions.</span>
