Titanium can be extracted from titanium chloride by the following reaction: TiCl4 + 2 Mg → Ti + 2 MgCl2 .The maximum theoretical mass of titanium that can be extracted is 72g. In the reaction, only 20 g of titanium was made. Calculate the percentage yield.

How do you identify the anode on a power source such as a battery? how do you identify the cathode? how are terms anion and cation?

Will mark brainliest how many electrons can be held in the energy level n = 4?
