Problem- The distinctive odor of vinegar is due to acetic acid, CH3COOH, which reacts with sodium hydroxide in the following fashion:
CH3COOH(aq)+NaOH(aq)-->H2O(l)+NaC2H3O2(aq)
If 3.95mL of vinegar needs 42.0mL of 0.125 M NaOH to reach the equivalence point in a titration, how many grams of acetic acid are in a 1.10qt sample of this vinegar?
I am stuck in between this question please help me out
Octane ratings are assigned to gasoline mixtures based on their ability to prevent knocking relative to isooctane. Estimate the energy released during the combustion of 1.00 mol of pure isooctane.
How many liters of oxygen are needed to exactly react with 19.8 g of methane at STP?
Consider following cell. SCE stands for the saturated calomel reference electrode, which has a fixed potential of 0.244 volt. Pt|VOSO4 (0.0586 M), V2(SO4)3 (0.190 M), HClO4 (0.0100 M) || SCE Calculate the cell potential.
The half-equivalence point of a titration occurs half way to the end point, where half of the analyte has reacted
How much heat in Joules was lost by the water. How much heat would be lost by the water if 1 mole of KCl had dissolved. c) What is (Delta Heat reaction) in kL/mole for this process, which can be written as KCl (s) --> KCL (aq)
Assuming no loss of water and a heat capacity for the vessel of 10.0 J/C, what is the final temperature of the system ( C of copper = 0.387J/gC) ? What is the final temperature?
The IR Spectra of solid benoic acid and liquid acetic acid are shown below. The OH stretch of a carboxylic acid is normally a broad peak from 3500-2500 cm-1. Explain why acetic acid has a very broad intense and prominent peak in this area but benz..
Steam at 35 bar as well as 600 K enters a throttling valve that decrease the steam pressure to 7 bar. Presuming there is no heat loss from the valve, Explain what is the exit temperature of the steam and its change in entropy
