A reaction of magnesium with nickel (iii) chloride will produce magnesium chloride and nickel. Using 31.76g of magnesium would produce how many grams of nickel?

1. Write and balance the equation.

2. Convert 31.76 g Mg to mols. mol grams/molar mass.
3. Using the coefficients in the balanced equation convert mols Mg to mols Ni.
4. Convert mols Ni to grams. g Ni = mols Ni x atomic mass Ni

To determine how many grams of nickel would be produced from the reaction, we need to calculate the molar ratio between magnesium and nickel.

Here are the steps to find the answer:

Step 1: Write the balanced chemical equation for the reaction.
2 Mg + 2 NiCl₃ → 2 MgCl₂ + 2 Ni

Step 2: Calculate the molar mass of magnesium (Mg) and nickel (Ni).
- Molar mass of Mg = 24.31 g/mol
- Molar mass of Ni = 58.69 g/mol

Step 3: Convert the given mass of magnesium (31.76 g) to moles.
- Moles of Mg = mass / molar mass
- Moles of Mg = 31.76 g / 24.31 g/mol
- Moles of Mg ≈ 1.306 mol (rounded to three decimal places)

Step 4: Use the molar ratio from the balanced equation to find the moles of nickel produced.
From the equation, we can see that the molar ratio of Mg to Ni is 2:2 (or 1:1).
Therefore, Moles of Ni = Moles of Mg ≈ 1.306 mol

Step 5: Convert the moles of nickel to grams.
- Mass of Ni = moles of Ni × molar mass of Ni
- Mass of Ni = 1.306 mol × 58.69 g/mol
- Mass of Ni ≈ 76.61 g (rounded to two decimal places)

Thus, using 31.76 grams of magnesium would produce approximately 76.61 grams of nickel.

To find the mass of nickel produced, we first need to determine the stoichiometry of the reaction. The balanced chemical equation for the reaction between magnesium and nickel (III) chloride is:

2Mg + 3NiCl3 -> 3MgCl2 + 2Ni

From the equation, we can see that 2 moles of magnesium react with 2 moles of nickel to produce the products.

Step 1: Calculate the molar mass of magnesium (Mg):
The atomic mass of Mg is 24.31 g/mol.

Step 2: Calculate the moles of magnesium used:
moles of Mg = mass of Mg / molar mass of Mg
= 31.76 g / 24.31 g/mol
= 1.31 mol

Step 3: Determine the ratio of moles between magnesium and nickel:
From the balanced equation, the ratio is 2 moles of Mg to 2 moles of Ni.

Step 4: Calculate the moles of nickel produced:
moles of Ni = (moles of Mg / moles ratio) * moles ratio of Ni
= (1.31 mol / 2) * 2 mol
= 1.31 mol

Step 5: Calculate the mass of nickel produced:
mass of Ni = moles of Ni * molar mass of Ni
= 1.31 mol * (58.69 g/mol)
= 76.94 g

Therefore, using 31.76 g of magnesium would produce approximately 76.94 grams of nickel.
