Complete and balance an equation for each reaction a)CaI2+Hg(NO3)2---> No reaction b)2Al+Cl2---> 2AlCl c)Ag+HCl---> No reaction d)C2H2+O2---> (i dont know this one sorrry) e)MgCl2---> Mg + Cl2 f)H2O2---> H2 + O2 i have no clue how to do the last one either. Ca(OH)2 + HCI →__ CaCl2 H2O 3. The magnesium is losing electrons, so it is undergoing oxidation. {eq}\rm 2Mg(s) + O_2(g) \to 2MgO(s) {/eq} It is explicitly mentioned that Mg is the limiting reagent. . MG+O2=MGO. Which most likely represents the starting equation? Compound states [like (s) (aq) or (g)] are not required. Hope it helped u . To balance an equation, we CAN change coefficients, but NOT SUBSCRIPTS to balance equations. The balanced equation for the reaction is: 2Mg(s)+O2(g)→2MgO(s) When 10.1 g of Mg are allowed to react with 10.5 g of O2, 14.5 g of MgO are collected. #2Mg(s)+O_2(g)->2MgO(s)# Now, there are equal amounts of magnesium atoms and oxygen atoms on both sides, and so the equation is balanced. A student balanced the chemical equation Mg + O2 → MgO by writing Mg + O2 → MgO2. Chemistry, 21.06.2019 20:30. (a) Write a balanced equation for the reaction Why is it 2Mg+O2->2MgO and not Mg+O->MgO . Here it has 2 Mg & 2 O on the left side and 2 Mg and 2 O on the right side and the Chemical equation is Balanced. On the left we have 2x O so on there right, we should mulitply MgO by 2 so we have on each side 2x O. Mg + O2 → 2MgO. For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but PhC2H5 + O2 = PhOH + CO2 + H2O will; Compound states [like (s) (aq) or (g)] are not required. The balanced equation is therefore. Achloride dissolves in water to form a colored solution. That is the basic principle for balancing an equation. Chemistry, 21.06.2019 17:30, edgartorres5123. What is the balanced equation for Mg+O2? Mg + O2 → MgO. On hte right side we have 2x Mg, so we have to multiply on the left side Mg by 2 to have the same amount of Mg on both sides.
