Math - Trig - Double Angles
I was looking at another of your questions, and in Npgm's proof, he/she modified both sides of the equation. You absolutely cannot do this. You must change only one side of the equation. My teacher called this "math etiquette," but it is etiquette that must be ...

In chemistry you can, with the help of a balanced chemical equation, convert anything to anything. The coefficients in the balanced equation are used for that purpose. First, the equation you wrote is not balanced. The proper equation is C6H12O6 + 6O2 ==> 6CO2 + 6H2O ?...

Two ways to do it but both actually are the same. k=0.693/t1/2 Substitute k into the equation below. ln(12/N) = kt Solve for N. I get 0.375 g. Second way: 1/(2n)* 12 [1/2(40/8)]*12 = ?? Again, 0.375g.

Sorry for pestering you on this but I really appreciate your help. The way I first did the equation, I had too many products. My question is when I do these should the products only be in the form of either a)CO and H2O or B)C and H2O? So if I set up the products to have ...
