英语化学求分子式和试验试!A compound contains only carbon,hydrogen,and oxygen.Combustion of 10.68 mg of the compound yields 16.01 mg CO2 and 4.37 mg H2O.The molar mass of the compound is 176.1 g/mol.What are the empirical and molecular for
It cannot be an element because there is more than one kind of nuclei in the CuO sample. It cannot be a mixture because a chemical bond is formed between Cu and O. It is a compound because the two elements are present in a fixed proportion by mass. A compound is a pure substance. ...
Phospholipids are the main component of the cell, or plasma, membrane. The cell membrane is important because it creates a thin, flexible barrier between the cell and the environment that is semi-permeable, only allowing certain molecules in and out....
6CO2 + 12H2O + Light Energy → C6H12O6 + 6O2 + 6H2O Here, six molecules of carbon dioxide (CO2) combine with 12 molecules of water (H2O) using light energy. The end result is the formation of a single carbohydrate molecule (C6H12O6, or glucose) along with six molecules each of oxygen...
a镍包铝粉是一种以铝为核心,外表均匀,完整的包覆一层镍壳的复合粉末涂料。本文采用热喷涂工艺,以Na2SiO3•9H2O为粘结剂,将镍包铝粉喷涂在机体材料60Si2Mn表面来研究镍包铝粉的耐磨性和耐腐蚀性,同时与60Si2Mn作比较。结果表明,在那些不严格要求使用碳化物那样硬的材料的地方,铝化镍涂层本身也可以考虑做耐磨涂层...
