(04.02 LC) A synthesis reaction can be identified because it only has pure elements on the left side of the arrow and compounds on the right side of the arrow. (2 points) Group of answer choices True False

they are made of gases.

they have a spherical shape.

they make energy through fusion.

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.

it is stable as it is in group 0 which have full outer shells of electrons

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.
