Please answer ASAP and correctly because I have recieved several wrong answers. Inorganic Chem2 Ch 18 #26 The weak acid Hz has a of 2.55 times 10-4. Calculate the pOH pf 0.0350 M HZ. pOH =
Please help. The answer to this question has been wrong both times I have submitted it on here. I really need to understand this. Assume you dissolve 0.175 g of the weak acid benzoic acid, CH, CO,H, in enough water to make 1.00 x 102 mL of solution and then titrate the solution with 0.182 M NaOH. K, for benzoic acid = 6.3 x 10-5.) CH3CO, H(aq) + OH(aq) = CHCO2 (aq) + H2O(C) What was the pH of the...
The answers I have are wrong. Pleaae answer the question correctly with steps included/explain how you found the correct answer. 9. (2 marks) Consider the reaction: 2 BrCl (g) 늑 Br2 (g) + Cl2 (g) A reaction vessel originally contains [BrCl]- 0.084 M only. Calculate the equilibrium concentrations K 9.01 x 10 at a given temperature of each species. [Bn] , [C12] = [BrCI]-
part b is wrong please answer correctly and asap!! The current supplied to an air conditioner unit is 5.22 amps. The air conditioner is wired using a 10-gauge (diameter 2.588 mm) wire. The charge density is n = 8.48 x 1028 electrons/m?. Find the following magnitudes. (a) current density (in A/m2) 992320.8 ✓ A/m2 (b) the drift velocity (in m/s) -7.31e-5 X m/s
please round correctly. Last few answers I recieved were wrong. Sid o: n P18-5 (similar to) Question Help 24 Cash acquisition decision Benson Oil is being considered for acquisition by Dodd Oil The combination, Dodd beleves, would increase its cash inflows by $28,000 for each of the next 5 years and by $50,000 for each of the following 5 years Benson has high financial leverage, and Dodd can expect its cost of capital to increase y from 11% to 14...
Please answer each question step by step and sometimes I can't read the handwriting, please 1) Calculate the Ka2 for oxalic acid (found in rhubarb and spinach) (H2C2O4) if a 0.35 M solution of Na2C2O4 has a pH of 8.87. 2) An aqueous solution of a weak acid, HWk (pKa = 5.25,) has a pH of 4.53. Calculate the molarity of the weak acid. 3) Calculate the pH of a 0.275 M solution of borax. (a detergent additive often used...
Please make sure parts e and f are correct, I have gotten two wrong answers so far. Thanks. Will give thumbs up. Please show work. Here is a list of hypothetical acids with their pKa's. The pKa values are valid at 25 °C. Acid pK a А 3.44 B 5.12 с 6.40 D 8.52 d. Which of these acids, in combination with its conjugate base, would be the best one to use to create a buffer with a pH of...
some acids + bases questions. please answer all parts! Thank you so much! 3a. Cyanic acid, HCNO, is a weak monoprotic acid with Ka = 2.0 × 10−4.Calculate the pH of a 0.820 M solution of this acid. Report your answer to TWO places past the decimal. 3b. Hypobromous acid, HBrO, is a weak monoprotic acid with Ka = 2.8 × 10−9.Calculate the pH of a 0.312 M solution of this acid. Report your answer to TWO places past the...
please help me please i dont have questions remaining anymore A solution is prepared by dissolving 0.060 mol of iodoacetic acid (Kg = 6.68x10-4) and 0.040 mol of sodium iodoacetate in water to a total solution volume of 1.00 L. First, calculate a pH for the solution by assuming that the concentrations of ICH CO2H and ICH CO2 are equal to the formal concentrations of the substances dissolved. Submit Answer Tries 0/5 Next, calculate the pH for the solution based...
Enter your answer in the provided box. Calculate the pH at 25 ° C of a 0.045 M solution of a weak acid that has Ka = 1.5 × 10−5.
