Question

In an experiment, 0.520 g of chromium metal reacts with 3.807 g of iodine. Using the conservation of mass law, predict the mass of product. 2 Cr + 3 I2= 2 CrI3

Answer 1

well conservation of mass means that mass can not be made or destroyed but turned into different forms.

Answer 2

\[2Cr+3I_{2}\rightarrow2Crl_{3}\]

Answer 3

so we want to know the mass of the final product right?
well I would think by following the law that the mass in the end will equal the mass in the beginning.
