As a result of this reaction, the temperature of the system drops from about 20176。 P4S10 tetraphosphorus decasulfide。 deca(10)（希臘語的前綴的意義：單（1）；二（2）；三（3）；四（4）；五（5）；六（6）；庚（7）；八（8）；九（9）十（10）；Naming molecular pounds（分子化合物命名）Note: when the prefix ends in a or o and the name of the anion begins with a vowel (such as oxide), the a or o is often dropped. The prefix mono is usually omitted for the firstnamed element.（好吧 這句我也不懂。hexa(6)。 di (2)。 (b) phosphoric acid.Naming molecular pounds （分子化合物的命名）Rule:The procedures for naming binary (twoelement) molecular pounds are similar to those for naming ionic pounds. The element with the positive nature is named first and also appears first in the chemical formula. The second element is named with an–ide ending. （雙原子分子命名，活潑的元素放在首位，第二個(gè)元素以ide結(jié)尾。陰離子的后綴——IDE與酸形成的加前綴和一個(gè)后綴IC：）（懂不？？不懂多看一下下面的兩個(gè)例子，留意前后綴）Eg:Chloride (Cl) to hydrochloric acid (HCl) sulfide (S2 ) to hydrosulfuric acid (H2S) Note: only water solution of HCl is called hydrochloric acid, the pure pound is called hydrogen chloride.、（注：HCl水溶液叫做鹽酸，純的化合物稱為氯化氫。 (d)magnesium sulfate。（3 離子）。carbonate, chromate, dichromate, ferrate,hydrogen phosphate, oxide, peroxide, sulfate,sulfide, sulfite, thiosulfate.(2 ions)。 selenite ion (?) perbromate (?) , hypobromite (?)Note: exceptions to rules（特殊例子）: permanganate ion is MnO4, manganate ion is MnO42. ferrate(or perferrate) FeO4，chromate CrO42, dichromate Cr2O72 練習(xí)：硒酸鹽離子（？）；亞硒酸鈉離子（？）過溴酸鹽（？）次溴酸，（？））Naming anionsPolyatomic anions with hydrogen ionsThese ions are named by prefixing the word hydrogen or dihydrogen, as appropriate,to the name of the hydrogenfree way is to use the prefix bi:
