6 x 10⁻⁵¹ = (0.15 M)² [S²⁻] [S²⁻] = (6 x 10⁻⁵¹) / (0.15 M)² Calculating, we find the minimum concentration of sulfide ion required: [S²⁻] ≈ 2.7 x 10⁻⁴⁹ M. check it calcution is write
For the following reaction, 4.91 grams of water are mixed with excess chlorine gas. The reaction yields 12.5 grams of hydrochloric acid.chlorine (g) + water (l) hydrochloric acid (aq) + chloric acid (HClO3) (aq) What is the theoretical yield of hydrochloric acid ? grams What is the percent yield of hydrochloric acid ? %
The distribution of Na* ions across a typical biological membrane is 10 mmol/dm3 inside the cell, and 140 mmol/dm³ outside the cell. At equilibrium, the concentrations across the membrane are equal. What is the Gibbs energy difference across the membrane at 37°C? The stated difference in concentration MUST be maintained by coupling to reactions that have at least your calculated difference of Gibbs energy. Ans: 6.8 kJ/mol
A monoprotic weak acid, HA, dissociates in water according to the reaction HA(aq) = H+ (aq) + A¯(aq) The equilibrium concentrations of the reactants and products are [HA] = 0.220 M, [H+] = 3.00 × 10−4 M, and [A¯] = 3.00 × 10−4 M. Calculate the value of pKa for the acid HA. pKa =
Triosephosphate isomerase catalyzes the conversion of glyceraldehyde 3-phosphate to dihydroxyacetone phosphate. This reaction has a Keq of 22.2. What is the standard free-energy change for this reaction? -7,680 kJ/mol -7.68 kJ/mol -3.34 kJ/mol -0.644 kJ/mol 7.68 kJ/mol
Example The reference range for blood pH is 7.35 – 7.42. What is this range expressed as [H+] in nmol l-1? Calculation: pH = - log [H+] 7.35 = - log [H+] [H+] = antilog -7.35 = 4.47 x 10-8 mol.l-1 = 44.7nmol.l-1 similarly: pH 7.42 = 38.0 nmol.l-1 Range [H+] = 38 – 44.7 nmol.l-1 If the blood pH decreases in an acidosis from 7.42 to 7.15, what is the change in [H+] in nmol.l-1? so this is example on the worksheet, but i still understand how to answer the question.
