Answer 1

I can’t see the image you mentioned — please either attach it here or paste the reaction and the given quantities (masses, molar masses if provided, etc.). Once I have that I’ll pick the correct answer and show the work.

Meanwhile, here’s the quick method I’ll use so you know what to expect:

1. Write the balanced chemical equation for the reaction from the image.
2. Convert the given masses of reactants to moles:
moles = mass (g) ÷ molar mass (g·mol⁻¹).
3. Determine the limiting reagent by comparing the mole ratio of reactants to the stoichiometric ratio in the balanced equation.
4. Use the limiting reagent’s moles and the stoichiometric coefficient to find moles of product:
moles product = moles limiting reagent × (coeff of product ÷ coeff of limiting reagent).
5. Convert moles of product to grams:
mass product (g) = moles product × molar mass of product.
6. Compare the computed mass to the choices (117.50, 109.98, 32.00, 12.31 g) and choose the closest.

If you paste the reaction and numbers now I’ll run the calculation and pick the best choice.
