Cory wants to do an experiment to confirm that matter is conserved during a chemical reaction. He decides to use the reaction of baking soda and vinegar. When added together, the two substances foam and bubble. Cory gathers the following equipment: a scale to measure masses a large flask in which to mix the vinegar and baking soda vinegar baking soda a lab book and pen What does Cory still need in order to do his experiment? A. a hot plate B. a way to measure the volume of liquids C. a way to calculate how much baking soda to use D. a way to capture and measure gas

personal, she chose to do it.

i believe the answer is 5,000

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
