What occupations have to use algebraic formulas? Also which formula is it and how is it used?
Q. I have to do a math paper on algebraic formulas used in the world. I have to write about a proffesion that uses a formula and how they use it. Would anyone know an occupation and the formula it uses?

A. Try these websites, so you have something to cite in your paper: there are many more, but these should get you started. Follow some of the links, I didn't look at all of them.

What are some important formulas used for solving algebra problems? When is each used and how are they used?
Q. This is a question I have, I'm in ninth grade, so it probably shouldn't be too hard. The thing I don't understand is that how is there just a few important formulas, when there are so many formulas over all. Can someone answer and explain this question to me please?

A. in order to solve an equation you must have an equal sign. it is not an equation unless you have a Left Hand Side (LHS) of the equation, and a Right Hand Side (RHS) of the equation. let me mention non equations for a paragraph: If there is no equal sign (or greater than or less than) you do the rules of Order of Operations to simplify, and that is all you can do when no equation, you cannot change what it is, just how it looks. example: 3/3. you can multiple by one (1/3)/(1/3) to make it into 1/1 = 1. but you did not change its reduced value. with equations, the Order of Operations allows you to strip away the parts on the LHS or RHS you do not want often, by doing the parts of the Order of Operations that are least. ex: 4*(3x + 2 )^2 - [cont.]

How do you write formulas for compounds and molecules in chemistry?
Q. 1.) a compound containing half as many barium atoms as iodine atoms 2.) a compound that contains twice as many potassium atoms as carbon atoms, and three times as many oxygen atoms as carbon atoms Any help would be appreciated! I dont understand how to write the formulas for either. i tried that for the second one and i got it wrong.
Asked by j - Sun Sep 28 14:24:23 2008 - - 3 Answers - 0 Comments
A. SGE, These sorts of problems work best taken one step at a time, and adjusting as necessary. For example, in the first example, if you have one iodine atom, you'd half one-half baruium atoms. You know you can't do that, so multiply everything by two: you get BaI2! In the second, if you have one carbon atom, you have two potassium atoms (K2C). If you have that one carbon atom, you have three oxygen atoms (CO3). Put the two together, and you get K2CO3! Not so hard, when you get the hang of it! Hope that helped!

A. Empirical formula: is the simplest formula that represents the whole number ratio between the elements in a compound. Examples: CH, CH4, CH2O, K2Cr2O7, K3Fe(CN)6 Molecular Formula: shows the actual number of each type of atom in a molecule. Examples: C6H6, CH4, C6H12O6, K2Cr2O7, K3Fe(CN)6. Molecular formula = (Empirical formula) x n n = integer The molecular formula is whole number multiple of empirical formula. If n = 1, both the formulas will be the same. To calculate the molecular formula from empirical formula and molar mass follow the steps 1-3 below: 1. Calculate empirical formula mass 2. Calculate the value of n by dividing the molar mass by the empirical formula mass 3. Multiply the empirical formula by n

What are the formulas for hexadiene and nonadiene?
Q. These are a few formulas I have to write for organic chemistry. What exactly does the suffix -diene mean? I wasn't really paying attention and I didn't get it. And how do you write the formula for hexadiene and nonadiene? Like... heptane would be C7H16, and etc.

A. -diene means that there are 2 double bonds. You have to designate in the name where exactly the double bonds are, like for example 1,3-butadiene is 4 carbons with double bonds starting at the first and third carbons. So hexadiene is going to be a hexane with 2 double bonds. Any saturated alkane has 2n+2 hydrogens. For every double bond you add, you take away 2 hydrogens. So hexane would be C6H14, and hexadiene would have 4 less hydrogens than that, so it would be C6H10. Nonane would be C9H20, so nonadiene would be C9H16. Hope that helps!
