Sahil watched a demonstration in which a scientist combined two substances in a sealed container and analyzed the results. the ending substances did not look the same as the starting substances.

sahil was given a diagram with the repeating groups of atoms that make up the starting substances, plus information about the properties of the starting and ending substances. he created a model of the repeating groups of atoms that might make up the two ending substances.

does his model correctly show why the properties of the ending substances are different from the properties of the starting substances? describe what could be correct or incorrect about his model.

hope its not to late..............Samira's model correctly demonstrates how the properties changed with the rearrangement of the atoms. However not all atoms are accounted for. There is a missing reactant. Samira's model correctly demonstrated how the atoms in two compounds reacted to form two new products. However, the elements present in the reactants side should be the elements that make up the new products in the product side. But as the diagram shows, Sameera has mistakenly added a new element to one of her products which will be wrong.

The model that has been correctly demonstrating the reaction has been Samira's model.

The reaction of reactant results in the change in the atoms bonded to the compounds and results in the product with varying amount of stoichiometric coefficient in the product.

Rearrangement of atoms in a reaction

The model that has been correctly demonstrating the rearrangement of atoms has been Samira’s model. The addition of the reactants and the product has been consisted of same atoms; however, there has been change in arrangement but not in number and type of atoms.

The model that has been correctly demonstrating the reaction has been Samira's model.
