Question

Na_2SO_4 (an ionic solid) is soluble in water (polar liquid) The Ozone layer is in the stratosphere at an altitude of about 30 Km. Electronegativity tends to increase as we go up a group (decrease or across a period from right to left A polyatomic ions is a group of atoms that is held together by ionic bonds and has acquired a charge. A polyatomic ions is a group of atoms that is held together by ionic bonds and has acquired a charge. Nuclear fission is the reaction that provides the sun's energy. A transmutation process is a nuclear reaction in which a nuclide of one element is changed into nuclide of the same element. The primary effect at ground level Ozone accumulation is skin cancer.
