For instance, the chemical formula for water is H2O. The subscript on the symbol for hydrogen is a two, which means there are two hydrogen atoms in water. The oxygen atom lacks a subscript, as there is only one atom of oxygen in the chemical formula for water. A chemical compound ...
(1)H2O:One day the science teacher asked the class,“What's the chemical formula for water?“A boy put up his hand, and the teacher said,”“Yes?”the boy said“HIJKLMNO”.“Are you trying to be funny?”asked the teacher angrily.“No, sir.”said the boy.“You said the formula ...
解答 71.B 细节理解题.根据小男孩的回答:"You said the formula was H to O."可知H2O应该是听上去和H to O一样,在这里是指发音一样.故选B.72.C 常识判断题.根据One day the science teacher asked the class,"What's the chemical formula for water?"并联系化学常识可知H2O就是水的化学分子式,所以...
Chemical formulae provide insight into the elements that constitute the molecules of a compound and also the ratio in which the atoms of these elements combine to form such molecules. For example, the chemical formula of water, which is H2O, suggests that two hydrogen atoms combine with one ...
