Title: Help with balancing chemical equations? Post by: RJW on Aug 25, 2012 I need help with these two equations, please. And if anyone has really good tips to make balancing easier, please share them with me !
a) Aluminum Iodide and chlorine gas react to form aluminum chloride and Iodine gas. b) Sodium sulphate and calcium chloride react to form calcium sulphate and sodium chloride. Thank you ! Title: Help with balancing chemical equations? Post by: rjt6250 on Aug 25, 2012 AlI3(it's Al and capital i) is the formula for aluminum iodide
And Cl(g) is chlorine g.The (g) symbolizes gas. Similarly (l) symbolizes liquid, (s) is solid and (aq) us aqueous meaning dissolved in water and is usually used for acids. 1) 2AlI3 + 2Cl (g) ---->2 AlCl + 3I2(g) I2(It's capital i) is diatomic meaning it will always come with a 2 next to it when by itself. Other diatomic molecules are hydrogen H2, nitrogen N2, fluorine F2, oxygen O2, iodine I2 , carbon C2, bromine B2. How I remember it is. Have - hydrogen H2 No- nitrogen N2 Fear - fluorine F2 Of - oxygen O2 Ice - iodine I2 Cold - carbon C2 Beer- bromine B2 2) Sodium sulfate= Na2SO4 Calcium chloride= CaCl2 Calcium sulfate CaSO4 Sodium chloride=NaCl So: Na2SO4 + CaCl2 ----> CaSO4 + 2NaCl |
