Anatomy of a chemical equation Chemists record chemical changes and reactions by combining symbols to create a chemical equation.
"Love is more a chemical equation than a coming together of hearts," says Dr Melanie Schlatter, Consultant health psychologist in Dubai.
When interpreting the chemical equation for the reaction between aqueous sodium hydroxide and dilute nitric acid, 20% of students appeared to hold the view that [Na.sup.+] and [NO.sub.-3] ions had reacted in aqueous solution to produce aqueous sodium nitrate.
Now sponsored by carlton.ie/galway city (that's a website for a hotel, by the way, not a chemical equation) it looks as competitive as the Pamplona bull run and could end up being just as messy.
According the presented chemical equation we can obtain by anaerobic fermentation from 1 kmol of 100% glucose 6 kmol (134.4 [m.sup.3]) of biogas (50% methane and 50% carbon dioxide).
The chemical equation is [Fe.sub.2][O.sub.3] + 3CO 2Fe + 3C[O.sub.2], which states that one molecule of iron ore ([Fe.sub.2][O.sub.3])and three molecules of carbon monoxide (CO), the latter produced by blasting hot air onto coke (prebaked coal), react to produce two molecules of iron (Fe) and three molecules of carbon dioxide (C[O.sub.2]).
Bargaining to strike a deal in Damascus, whether in the world of commerce or politics, is defined by a few basic rules: The process takes time, it often requires third parties to come in and out of the picture like catalysts in a chemical equation, some gains are not calculated immediately but materialize later, and a deal is consummated only if all sides obtain their key demands in a win-win situation.
By keeping this chemical equation balanced, pH can be maintained at the appropriate level.
And while I know I am not as good as they think I am, I sometimes allow the chemicals, the serotonin and dopamine, to course and snap and fire all along my internal pathways before I pause and say, "No, it was you." Or maybe it was us, and the chemical equation, when complete, is a narrative of the balance that has occurred between two parts.
Well I'm assured that the chemical equation - a hybrid of logical and emotional thought - is not as complicated as it first looks.
This shifting equilibrium that occurs when the amount of a material on one side of a chemical equation changes we will here call "mass action." The equilibrium shift--say moving the reaction to the left--always works in a direction that reduces the original change.
