Balanced equation for the reaction is; 2Mg + O₂ --> 2MgO stoichiometry of Mg to O₂ is 2:1 we need to first find the limiting reactant number of Mg moles - 0.66 g / 23 g/mol = 0.029 mol number of O₂ moles - 0.43 g / 32 g/mol = 0.013 mol If Mg is the limiting reactant 2 mol of Mg reacts with 1 mol of O₂ then 0.029 mol of Mg reacts with - 0.029/2 = 0.0145 mol but only 0.013 mol of O₂ is present therefore O₂ is limiting reactant. amount of product formed depends on amount of limiting reactant present, stoichiometry of O₂ to MgO is 1:2 when 0.013 mol of O₂ reacts - 0.026 mol of MgO is formed mass of MgO produced is - 0.026 mol x 39 g/mol = 1.014 g 1.014 g of MgO formed
Thermal Energy- is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.
Heat-energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects.
Temperature- is a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object, which is a type of energy associated with motion.
