A. Vinegar which is just a dilute acetic solution, is very common and versatile. The concentration of store-bought vinegar around a 5% solution by mass and is density is approximately 1.01 G/ml
B. Suppose I dilute does vinegar into a bottle 23 pours water plus one part vinegar in other words I make a solution that is 25% as strong as it was. Determine the molarity of the new vinegar solution.
C. How many Adams are carbon are in the 2 cups of this new vinegar you made in part a please show all work
Joseph Priestley prepared oxygen by heating mercury(II) oxide. The compound HgO is stable at room temperature but decomposes into its elements (Hg and O2) at high temperatures. What conclusions can be drawn concerning DH and DS for this decomposit..
A piece of magnesium (mass=16.2 grams) reacts completely with 10.7 grams of oxygen. In the second reaction you have 61.4 grams of magnesium and 103.7 grams of oxygen
All molecular compounds may have London, dipole-dipole, and hydrogen-bonding intermolecular forces affecting their physical and chemical properties.
a. what are the energies of the n=1-7 levels? b. what is the energy difference between n=6 and n=7? c. what does this very approximate calculation compare with experimental values
Dye 2 failed to quench the synthesis of benzpinacol however afforded a red flurorescence in the chemiluminescent reaction. Explain what can say about the approximate energy levels of the S1 and T1 states of the two dyes
Why is comparing moles of reactants without using the balanced equation not the proper way to determine the limiting reactant. Is it because you need to have it balanced to understand the moles being used correctly
what is the molarity of a solution prepared by dissolving 2.06g of NaOH in a volume of 500.0ml?
As part of a soil analysis on a plot of land, you want to determine the ammonium content using gravimetric analysis with sodium tetraphenylborate, Na B(C6H5)4-. Unfortunately, the amount of potassium, which also precipitates with sodium tetrapheny..
2 L of an unknown concentration of the weak base ammonia are standardized. 50.0 mL of the basic solution are titrated with 0.200 M HCl. The end point occurs after 71.0 mL of acid are added. What is the concentration of ammonia in the 2 L flask
The equilibrium constant at 25°C is 8.9 × 10-12. One hundred grams of magnesium hydroxide is added to 1.00 L of water and equilibrium is established.
Which would involve the emission of a higher frequency of light, the transition of an electron in an H atom from the n = 5 to the n = 3 level or a similar transition in an X atom?
Problem- What is the relative stability of alpha and beta-d-glucose pentaacetate? How can you account for the product mixtures that form under conditions of acidic and basic catalysis in the synthesis of Alfa and beta D-glucose pentaacetate
