First, verify that the equation contains the same type and number of atoms on both sides of the equation. Cami, debes tener claro que no todo el "N" del HNO3 se reduce (esto se explica porque existe el Cu (NO3)2 como producto en la ecuación y éste no sufre cambios en el estado de oxidación) por lo que al balancear, el NO3 (-) no te dará el coeficiente correcto. Thus, it is reduced. 2:3.11.19 g/mL will be needed to react with 9. Thus, it is reduced. 3Cu (s) + 8HNO3 (aq) à 3Cu (NO3)2 (aq) + 2NO (g) + 4H2O (l) If this reaction took place rather than the first reaction, would your yield of CuCl be affected assuming you started with the same amount of copper metal? Explain your answer.3Fe(NO3)2 + 8HNO3 + 12H+ + 12e- → 3Fe(NO3)3 + 5NO + 10H2O 7. 6 D. From the equation: 3Cu + 8HNO3 ---> 3Cu(NO3)2 + 4H2O + 2NO, calculate the mass of copper needed to react with 63g of nitric acid.19 g/m: will be needed to react with 9. Óxido Nítrico - NO. Count The Number of Each Atom. C.3CuS + 8HNO3 → 3S + 2NO + 3Cu(NO3)2 + 4H2O 6. 82. tentukan reduktor dan oksidator dari reaksi 3Cu+8HNO3=3Cu (NO3)+2NO+4H2O. Durante la reacción, el nitrógeno presente en el ácido nítrico cambia su estado de oxidación de +5 a +2. Do not select this one! This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Name (a) a metallic hydroxide soluble in excess of NH 4 OH. Question: if 5. BALANCEADA. 4. Hence, copper acts as There are 4 easy steps to find the molar mass of 3Cu + 8HNO3 + 3Cu(NO3)2 + 2NO + 4H2O based on its chemical formula. Calculators. 3CuS+8HNO3→ 3Cu(NO3)2+3S+2NO+H2O 3CuS+ 8HNO3→3Cu(NO3)2+ 3S+2NO+H2O 3CuS+ 8HNO3→ 3Cu(NO3)2+ 3S+ 2NO+ 4H2O. ¿Cómo es la proporción de la densid … 3Cu(NO 3) 2(aq) + 2NO (g) + 4H 2 O (aq) How many grams of HNO 3 are needed to dissolve 11.86 mol de Agua 2.
