What is the easiest way to memorize chemistry formulae?
Q. For anybody who did well on the AP chemistry, what is the best method to memorize formulae? And did you really need a lot of formulae and "constants" memorized for the multiple choice part where you only get the periodic table? I understand you get some formulae for the written part.

A. i pinned them up by my sink and read them while i brushed my teeth. that way you read them for around ten minutes each day and they soon sink in. i revise a lot of formula this way.

In a microsoft excel worksheet, is it possible to hide the formulae only?
Q. I would want a situation where if one opens the worksheet they can see the figures, but not the formulae behind the figures. Thank you. I would want to keep the worksheet as a shared worksheet, where others may be able to work with the entry of data to the cells from where the formulae links.
Asked by onelife006 - Tue Jun 6 13:11:57 2006 - - 4 Answers - 0 Comments
A. Right click on the cell that has the formulae, Select Format Cells, Choose Protection, Tick Hide. now this does not hide the cells until the worksheet is protected so first, if there are cells where input is required: Select all the cells that require data input by using mouse and CTRL key, then follow above for Protection but just Untick Locked. Finally, choose Tools from the menu, then Protection and Protect sheet, you will be given the chance to give a password or you can leave it blank. (Before adding any other information to your spreadsheet you will have to Unprotect it first)

Can we add common worksheet function with different formulae in Excel?
Q. The very frequent trouble with me is to make formulae in different cells forgetting something and add after words a common function in all formulae by editing and typing all such formulae. Is there any easy way to do this? Suppose I have (A1*b1)+c1formula in d2 and (a2*b2)+c2 formula in d2, is there any easy way such as copying etc., to add work sheet function =round() with all formulae?
Asked by dsilva_manuel - Thu Jan 24 03:00:38 2008 - - 1 Answers - 0 Comments
A. You probably meant that (A1*B1)+C1 is in D1, not D2. If you're just computing a result in the D column, the same formula will work everywhere, because cell references (A1, B1, etc.) are relative. (btw, you can make them absolute using the $, $A$1, for example). Just change the formula in D1 to be whatever you need, with round(), and copy it directly down the D column. The cell references will change to always use the row you need, as long as you don't use $. For example, if I change D1 to "=(A1*Round(B1,0))+C1", copy this cell, and paste to D2, I'll have "=(A2*Round(B2,0))+C2". Basically, change it once and copy the change down. The only reason this may not work is if you're changing the basic formula, like you multiply B and C,… [cont.]

A. The lengths of the arc of a degree along longitude and latitude are not constant. WGS84 ellipsoid has its own way of defining the earth, based on star positions and complex calculations. It is not possible to go into the details of such calculations here. I think you can try the following site instead, which gives a detailed account of various attributes and parameters of WGS 1984. I hope this will serve your purpose.

What are the formulae for maximum bending moment and deflection in a trimming joist with UDL & point load ?
Q. Hi! Does anyone know how to calculate the maximum bending moment and deflection in a simply supported beam with a UDL acting across its entire length and a point load acting at some distance other than the centre of the span? It's for the design of a timber trimming beam in a loft conversion. Any help would be much appreciated! Thanks.
Asked by cmagicroundabout - Sat Apr 12 08:01:52 2008 - - 2 Answers - 0 Comments
A. Now the problem lies in the fact that the point load is at any point. There really is no easy formula, you can use superposition but it will be difficult to get the max moment via that method. The reason for this is that the max moment from the udl is at the mid span and the max moment from the point load is at the point load. Don't recommend this method. I recommend to draw out the FBD and calculate the shear and moment diagrams, and read the max moment off of that. If your not sure how to do this use the worst case scenario udl w/ the point load mid span, it will be Conservative but still safe. How conservative depend on the location of the point load. use: wL^2/8 + PL/4 = Mmax Deflection is a different problem but similar, their… [cont.]

Is the formulae for chlorine gas the same as chlorine water ?
Q. I know that the chemical formulae must be different for a chlorine gas and chlorine water.

Can someone out there who knows please explain how you change the element of chlorine (or anything else for that matter) into a gas or waer, thanks a million

A. I assume you mean chlorinated water Chlorine is Cl2 Chlorinated water is a mixture of chlorine, water, hypochlorous acid and hydrochloric acid. The exact formula and proportions of each depends on the ph quote from wikipedia When chlorine is added to water, it reacts to form a pH dependent equilibrium mixture of chlorine, hypochlorous acid and hydrochloric acid: Cl2 + H2O HOCl + HCl Depending on the pH, hypochlorous acid partly dissociates to hydrogen and hypochlorite ions: HClO H+ + ClO- In acidic solution, the major species are Cl2 and HOCl while in alkaline solution effectively only ClO- is present. Very small concentrations of ClO2-, ClO3-, ClO4- are also found[1].

Why do the roman numerals mean in the name of chemical formulae?
Q. I have a few questions: Is this numbering limited only to the transition metals? As if it is something like Tungsten (VI) Fluoride it refers to Tungsten. Does VI mean the charge?

A. yes they do mean the charge e.g. Iron (II) Oxide = Fe 2+ O 2- Iron (III) Phosphate = Fe 3+ PO4 3- Copper (II) Sulphate = Cu 2+ SO4 2- Technically they are only linked to transition metals, because transition metals can have different valencies/charges. Metals only lose electrons so they are always with a positive/+ charge. some elements can have a 6+ charge but i havent seen one before, but some transition metals might be able to. e.g. your example Tungsten (VI) flouride is WFe6 is W 6+
