WebFor the iron-carbon system the eutectic point occurs at a composition of 4.26 wt% C and a temperature of 1148°C. Cast iron, therefore, has a lower melting point (between approximately 1150°C and 1300°C) than traditional steel, which makes it easier to cast than standard steels. Because of its high fluidity when molten, the liquid iron easily ... WebAug 27, 2011 · Protons = 17, electrons = 18 There are two isotopes differing in neutron number only : Cl-35 (75%) having 35-17= 18 neutrons Cl-37 (25%) having 37-17= 20 neutrons Wiki User ∙ 2011-08-27 14:01:17...

WebCarbon with a -2 charge must have 8 electrons (6 protons/electrons in neutral atom plus 2 more electrons to give it a -2 charge = 8) Isotopes are simply specifying the number of neutrons and protons (together called nucleons) in the atom. So, Carbon-12, which has an atomic mass number of 12, has 6 neutrons (12 nucleons - 6 protons = 6 neutrons). WebIf 8 moles of FeS are burned (combined with oxygen) how many moles of sulfur dioxide are produced? 4FeS + 7O2 = 2Fe2O3 + 4 SO2 8 Name the reactants that is not oxygen in the following reaction: 4FeS + 7O2 = 2Fe2O3 + 4 SO2 cuh rechargeable
