Everything that we glissando or see is composed of chemicals. Chemistry comprehends with your plain products, the way you feel and the way the world works. Chemistry is the expertise of structures, compositions, properties and reactions of matter, especially of atomic and molecular systems. Like mathematics, there are many chemistry tutors online for expose, as math tutors fuse your math problems, colloid chemistry tutors and tools execute a will interpret all your chemistry problems.<\p>

<\p>

Thousands regarding websites are articulated on help students present-time learning chemistry and other subjects online. Allness parents wants that their youth should score pleasant marks in class and should top the class for this parents also make efforts in there with their kids, They send their kids to best preparation classes, coaching centres etc. Sometimes this is also not very right, as tuition classes are some sort similar headed for school classes, one teacher and many students, and teachers don't remunerate attention to all and every pundit.

The other problems are set up exactly the same as this one, except for different mL of NaOH. I hope that this helps you to understand.

You have to get the new molarities first, which you can do with the starting mL and starting molarities given to you by getting the moles of each; and then you can get the new molarities by dividing the moles by the new volume of the total solution.

Then you need to get the pH of acetic acid and NaOH separately. You can usually get the acid dissociation constants from your textbook's appendix, then you use that to help you get the concentration/molarity of H, in order to get the pH.

You can use the ion-product constant for water in order to get the molarity of H ( since you know the molarity of OH-).

Someone, please correct me if I did anything wrong. I did this problem at 1 A.M. so I wouldn't be surprised if there's a mistake in there somewhere.

I hope you can read this, and good luck! Don't be afraid to ask more questions.

Bug 3 of 4. Sherlock.

It should be OH instead of OE. There is no such functional group called "OE".No wonder he can't understand, ha ha.

Dear chemistry,

I like you. I really do. Blowing things up is always fun. Explosions are awesome. But when you have extraneous information like this: 

When you were 12 years old and your height was 4 foot 3 inches on the 14th day of the 3rd month, the atmospheric pressure was 0.94 atm and the localized gravity was 9.7993 m/s2.  Also assume that the density of water that day was 1.00000 g/cm3 and Jupiter’s mass was 1.900523 x 1027 Kg.  The Earth was 113.4 days away from a partial solar eclipse and our atmosphere happened to have a temperature of - 6.4 °c.  You asked your mom for a second piece of apple pie and she said “no,” and you also happened to have about 3.2 x 1020 atoms of radioactive C-14 in your body; normally you have about 10% less than that.  You are holding a balloon that contains 1.45 moles of H2, 2.44 moles of CO2, 0.00 moles of vacuum, and 13 atoms of Fe.  I’m sorry, I forgot that comet Shoemaker-Levy 9 crashed into Jupiter a few weeks earlier, making it a tiny bit more massive - Jupiter’s mass was actually 1.900524 x 1027 Kg.  Your psychological condition could be described as slightly manic yet totally euphoric.  If Abraham Lincoln happened to call you on the phone that day and ask you “What is the volume of your balloon” you would respond...?

It's a little much. I only need to find the volume of a balloon to tell Abraham Lincoln when he calls? Of COURSE I need to know that the Earth was 113.4 days away from a partial solar ecplice and Jupiter's mass was 1.900524 x 1027 Kg. WHAT was I thinking?
