Water is made up of two elements, hydrogen and oxygen. How many hydrogen atoms are there in one molecule of water? A. One B. Two C. Three D. Four 相关知识点: 试题来源: 解析 B。解析:一个水分子的化学式是H₂O,这表示一个水分子由两个氢原子和一个氧原子组成,所以答案是B。A选项一...
How could such complicated molecules have been formed and have started to interact in the primitive soup Scientists were stumped. Then, in 1953, two scientists named Harold Urey and Stanley L. Miller did a very simple experiment to find out what had happened on the primitive Earth. They set ...
These are molecules with millions of hydrogen, carbon, nitrogen, and oxygen atoms. How could such complicated molecules have been formed in the primitive soup? Scientists were stumped. Then, in 1953, two scientists named Harold Urey and Stanley L. Miller did a very simple experiment to find ...
Atoms form molecules and compounds by sharing electrons to create chemical bonds. Understanding the nature of this bonding begins by knowing the number of electrons associated with each atom. With the information from a periodic table of the elements, and some straightforward arithmetic, you can calc...

(O2) is being forced through the catalyst, where it forms two oxygen atoms. Each of these atoms has a strong negative charge. This negative charge attracts the two H+ ions through the membrane, where they combine with an oxygen atom and two of the electrons from the external circuit to ...
For example, to find the molecular mass of NH3, the first step is to look up the atomic masses of nitrogen (N) and hydrogen (H). H = 1.00794 N = 14.0067 Next, multiply the atomic mass of each atom by the number of atoms in the compound. There is one nitrogen atom (no subscript...
