Everyone knows that helium makes your voice high pitched, but there is another gas with the opposite effect. It is composed of the elements Sulfur and Fluorine, with the molecular formula SF6. Let's assume that we perform a reaction in the lab at constant temperature and pressure and that both Sulfur (assume sulfur is monatomic in this state) and Fluorine are in gaseous form. What ratio of elements would give us only product without excess starting material? 3 Moles Sulfur and 1 Mole Fluorine. 1 Mole Sulfur and 3 Moles Fluorine. 1 Mole Sulfur and 6 Moles Fluorine. 6 Moles Sulfur and 1 Mole Fluorine. Which of the following can be concluded from law of multiple proportion: the elements consist of identical particles of same mass. some elements consist of diatomic molecules. different elements have different masses. each compound consist of identical molecules. Two elements, Sodium and Chlorine, react to form crystals out of a water solution. What can be said about the space between the atoms in the crystal lattice? The atoms pack so tightly that they completely flatten against each other In between the atoms is air. O There is nothing but space between the atoms in the crystal O Water molecules get stuck in between the sodium and chlorine atoms.
