Question

one possible reason for obtainig a lower than expected yield during an experiment is ?

MULTIPLE CHOICE QUESTIONS 1. The density of an object that floats in water is: a) Greater than the density of water b) Equal to the density of water c) The result of the difference between the density of the water and the density of the container Lower than the density of water 2.

When a student places it into a container of water, the liquid level rises from 21.25 mL to 26.47 mL. What is the density of the ore? a) 0.312 g/ml b) 0.63 g/ml c) 1.58 g/ml d) 3.21 g/ml

Explanation / Answer

4. Option c: Side reaction. Two or more reactions when occur simultaneously, so that some reactants are converted into by-products. Which decreases yield of a reaction.
