nickel (II) oxide heated with carbon

To answer the question, "nickel (II) oxide heated with carbon," we can break it down into steps:

Step 1: Identify the reactants and products.

• Reactants: nickel (II) oxide (NiO) and carbon (C)
• Products: nickel (Ni) and carbon dioxide (CO2)

Step 2: Write the balanced chemical equation. The balanced equation for the reaction is: NiO + C -> Ni + CO2

Step 3: Determine the stoichiometry. From the balanced equation, we can see that 1 mole of NiO reacts with 1 mole of C to produce 1 mole of Ni and 1 mole of CO2.

Step 4: Calculate the molar masses.

• Molar mass of NiO: 74.69 g/mol (nickel: 58.69 g/mol, oxygen: 16.00 g/mol)
• Molar mass of C: 12.01 g/mol
• Molar mass of Ni: 58.69 g/mol
• Molar mass of CO2: 44.01 g/mol (carbon: 12.01 g/mol, oxygen: 16.00 g/mol)

Step 5: Calculate the mass of reactants and products.

• Given the mass of NiO and C, you can calculate the moles of each using their respective molar masses.
• Then, using the stoichiometry from the balanced equation, you can determine the moles of Ni and CO2 produced.
• Finally, convert the moles of Ni and CO2 back to mass using their respective molar masses.

Step 6: Analyze the results. By following these steps, you can determine the mass of nickel and carbon dioxide produced when nickel (II) oxide is heated with carbon.
