Answer:
I'm afraid not, the image is too blurry
Answer:
Based on the info given, no calculation needed .... it's 1.00 Liter
Explanation:
All you've given is the molar concentration which by definition is the moles solute per Liter of solution. That is, 3.5M H₂SO₄(aq) solution means 3.5 mole H₂SO₄ per 1.0 Liter.
Answer:
You need to count all the atoms on each side of the chemical equation. once you know how many of each type of atom you have,you can only change the coefficient. (the numbers in front of the atoms or compounds
Explanation:
The ionic strength of a solution, I, is defined as
I=1/2 Σ m_i z_i^2
Where m_i is the concentration of the ion, and z_i is the charge of the ion.
For 1 M NaCl solution, Ionic strength I = ½ (1*12 + 1*12) = 1.00;
For, 1 M (NH4)2SO4, concentration of [NH4] = 2 M and [SO4] = 1 M;
I = ½ (2*12 + 1*22) = 3.00;
so ionic strength of 1 M (NH4)2SO4 is different, therefore it is a serious error.
The second ionization energy of Mg is larger than the first because it always takes more energy to remove an electron from a positively charged ion than from a neutral atom. The third ionization energy of magnesium is enormous, however, because the Mg2+ ion has a filled-shell electron configuration.
