please show tables and legible work Exercise 5. How many mL of 1.20M HCl would it...
please help. i will give you a thumbs up Exercise 5. How many mL of 1.20M HCl would it take to just exhaust 100.mL of a buffer that is 0.300M in HCO3 and 0.200M in CO32-? a) Writoala balanced net ionic reaction that occurs when the HCl is added. b) What are the initial mmoles of CO2-before reaction? c) How many mmoles of HCl will be required to neutralize the buffer. d) How many mL of the HCl solution will...
2. How many ml of 10.0M HCl do I need to add to 100ml of 1.00M NaOH to get a solution with pH = 7? 3. 75.0ml of 1.00M HCl is added to 100ml of 1.00M NaOH. what is the pH of the resulting solution? If I can get help with these two, I can do the others. Thank you. 2. (1pt) How many ml of 10.0M HCl do I need to add to 100ml of 1.00M NaOH to get...
Please, show work. •How many moles of HCOOH (pKa = 3.86) and NaHCOO are required to make 1 L of 0.5M formate buffer at pH = 4? •How many moles of HCOOH and NaOH are required to make 1 L of 0.5M formate buffer at pH = 4? •How many moles of NaHCOO and HCl are required to make 1 L of 0.5M formate buffer at pH = 4?
please show work How many grams of HCl, are needed to produce 125 ml of carbon dioxide gas at STP in the following reaction? CaCO3(s) + 2 HCl(aq) - -> CaCl(aq) + CO2(g) + H20(1) In a reaction similar to this laboratory experiment, 0.625 g of aluminum metal was completely consumed and the H, gas collected over water at 55.0°C and atmospheric pressure of 759 mm Hg. What was the volume of H, gas produced? (Be sure to correct H2...
Please show legible work! thank you. e. Assume a starting amount of 20 mL of 6M AgNO3 and 40mL of 5M Na2CO3. Calculate the limiting reactant and theoretical yield for this reaction. (6pts)
An experiment in a general chemistry laboratory calls for a 2.00-Msolution of HCl. How many mL of 11.9M HCl would be required to make 250 mL of 2.00 MHCl? Please show me the answer step by step Thanks..
How many milliliters of 11.0 M HCl(aq) are needed to prepare 725.0 mL of 1.00 M HCl(aq)? Please explain and show work.
please show work so: 1 ml stock 10 ml final -0.5 mL of stock -5 ml final volume While I have used 1:10 as a standard the same rules apply for all dilution factors. Try these problems: x 0.5 X0.5 1. You need to make a 1:25 dilution factor. If you final volume is 25 mL this means that you need_ _mL of stock and mL of solvent to make your final volume of 25 mL. 2. If you needed...
Please show all your units and work. Thank you Legible (neat) work would be appreciated so I could read it, thank you again!
#4.. please show work and dont skip steps. trying to learn how to do this for the actual biochemistry lab PART B. PRACTICE CALCULATIONS Convert units (show your work!): a. 0.01 ml b. 0.05 M = MM c. 0.2 M = mM d. 10 mM - M 2. Molar mass of Na olar mass of NaOH is 40 /mol. How many grams of NaOH do you have to take to prepare a. 11 of 10 M solution of NaOH? b....
