Suppose you have 25.00 mL of phosphoric acid, and you do not know what it's concentration is. If you titrated it with a 0.733 M potassium hydroxide solution, and it took 39.50 mL of the base to neutralize the acid. what was the concentration of the phosphoric acid?
Write the neutralization reaction, balance it, Please provide each steps for above problem.
What is the pH of the buffer that results when 12.5 g of NaH2PO4 and 22.0 g Na2HPO4 are mixed and diluted with water to 0.500 L. The acid dissociation constants for phosphoric acid are
Glycerol esterified with three fatty acids is called a sphingolipid d. Waxes are esters of long-chain alcohol and long-chain fatty acid e the short hand notation for fatty acid
Rutherford fired positively charged particles at metal foil and concluded that most of the mass of an atom was..a) in the electrons.
Calculate the mass of solid NaCl that must be aded to 1.50 L of a .100 M AgNO3 solution to precipitate all the AG+ ions in the form of AgCl
Assume that the coffee has the same density, 0.997 g/mL, and specific heat capacity, 4.184 \rm J/(g\cdot K), as water over this temperature range.
The atmosphere slowly oxidizes hydrocarbons in a number of steps that eventually convert the hydrocarbon into carbon dioxide and water. The overall reactions of a number of such steps for methane gas is as follows
A 2.158g vitamin C tablet was analyzed for ascorbic acid content. 1.785g of the tablet was used to make 100mL of solution for titration. A 25.00mL sampled of the solution required 11.85mL of 0.0982 M NaOH for neutralization.
A mixture of 0.146 moles of C is reacted with 0.117 moles of O2 in a sealed, 10.0L vessel at 500 K, producing a mixture of CO and CO2. The total pressure is 0.640 atm. What is the partial pressure of CO?
We add excess Na2CrO4 solution to 17.0 mL of a solution of silver nitrate (AgNO3) to form insoluble solid Ag2CrO4. When it has been dried and weighed, the mass of Ag2CrO4 is found to be 0.310 grams.
according to the following reaction how many grams of ammonia will be formed upon the complete reaction of 30.1 grams
