A machine which cost P 10,000 was sold as scrap after being used for 10 years. If the scrap value was P 500, determine the total depreciation and book value at the end of the 5th year using straight line method.
EXPERT ANSWER
Determine the forces inmembers BC, BG and FG.
EXPERT ANSWER Note: First we calculate the reaction forces Note: Now we proceed to do method of sections
Derive a titration curve for 50.00 mL of 0.0100 M Sr2+ with 0.0200 M EDTA in a solution buffered to pH 11.0. Calculate pSr values after the addition of 0.00, 10.00, 24.00, 24.90, 25.00, 25.10, 26.00, and 30.00 mL of titrant.
EXPERT ANSWER Initial [Sr2+] = 0.0100 M Initial volume of Sr2+ solution = 50.00 mL Initial milimoles of Sr2+ = 50 * 0.010 = 0.5 mmoles At pH = 11, 4 of EDTA = 0.85 KSrY = 4.3×108 Conditional constant, K’SrY = 4 * KSrY = 0.85 * 4.3×108 = 3.655×108 When 0.0 mL EDTA is added – [Sr2+] = 0.010 M …
What is the volume of 0.1 M AgNO3 needed to precipitate all I- and CN-in a 50.0 mL solution that is 0.0100 M in l- and 0.0500 M in CN-?
EXPERT ANSWER Answer Step 1 Silver nitrate reacts with CN– to form a white precipitate of silver cyanide. Silver nitrate react with I– to form precipitate of AgI. Step 2
Which analyte will have a greater change of pAg at equivalence point region? I- (iodide) or IO3-(iodate)?
EXPERT ANSWER Answer: This is the Iodometric involes indirect titration of iodine liberated by reaction with an analyte,whereas iodometry involes direct titration using iodine as titrant. Redxc titration using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used sphecifically titrate iodine.In this titratio starch is used as indicator since …
