Faster than light

The velocity of neutrinos determined by the OPERA detector in the CNGS beam, was repeated and analogous results were obtained. I am sure more independent attempts will have to be made before possibilities for all anomalies are rectified. Here is a link to the article and the pdf file with design details, interesting read for the scientifically inclined.

Q1. Ksp = 1E-24 M^2
Q2. Ksp = 8.79E-18 M
Q3.a. 3.52E-4M = Solubility
Q3.b.If the Ksp values are close and the ionic ratios are different you must calculate the solubility to determine which is the most soluble.
Q4.1.59E-9M^2
Q5. x=1.0E-5 mol
Q6.a. 1.2E-3M
Q6.b. Solubility = 7.1E-7M – assumption 7.1E-7<< Q7. 1.43g (Limiting reagent question)

Solubility Product Lab

Focus is on Initiating and Planning

Write a lab report for determining solubility product for Ca(OH)2 based on the questions suggested.

  • What are the theoretical considerations for explaining solubility of sparingly soluble salts and predicting the precipitations of these salts.
  • How would you determine the solubility product of Ca(OH)2
  • The suggested method was titration, alternate methods are welcome
  • Include every step in detail, meaning a proper practical procedure.
  • The analysis part needs to be done only when the lab is performed in class.
  • However speculation on possible sources would be good.
  • A written submission is required on Monday.

iCloud and Document syncing

This is a brief write up on “How to use iCloud to store documents like Pages, Keynote and Numbers and download them onto your  PC”

  • Install iCloud application for PC by downloading it from the following site -Download here
  • Install control panel by double clicking on the exe file that you just downloaded, login in using your apple id, or apple account to see all your documents.

After you have logged in you will technically be able to see all your photos, mails, outlook contacts etc. if you have already enabled sharing them while you set up your iCloud on your iPad or iPhone. But you will not be able to see your iWorks documents, you may be able to see them after you click manage however not downloadable at this time.

I am more interested in downloading documents made on my iPad like Pages, Key note and Numbers. What I noticed is that I am unable to access any of my documents that are on iWorks from the control panel.
So this is what you do.

Go to iWorks using this link

  • This link will open up a secure page to log you into your iCloud account on the browser
  • Enter your login credentials
  • Now you will be able to see all your documents Keynote, Pages and Numbers
  • Now if you select a document it will give you the option of downloading it as word, pdf or pages format. Appropriate formats are given for Keynote and Numbers.

 

However I find using dropbox much more convenient, after all this work around. I can access my documents directly in the dropbox program without using a browser. That is way better and convenient.

Only advantage for me now is that I can acces my Pages, Keynote and Numbers documents which I created on my iPad using iCloud on my PC and print them easily

Note:If you need to sync all your music, photos etc go to iTunes preferences, select sharing and check mark “share my library on my local network”, this should complete the process of sharing all other data

  • Copy and paste it
  • Now you are all set to use the wordpress stats
  • The same api key can be used to set up the akismet filter to control spam on your comments.
  • Now both your stats counter and akismet filter should work fine.

For you stats to be activated properly give some time as your stats counter does not have any information at this time.
Have fun with wordpress.
