Heat loss through thermopane double window. a double-glazed window called thermopane is one in which two layers of glass are separated by a layer of dry, stagnant air. in a given window, each of the glass layers is 6.35 mm thick separated by a 6.35 mm space of stagnant air. the thermal conductivity of the glass is 0.869 w/m*k and that of air is 0.026 over the temperature range used. for a temperature drop of 27.8 k over the system, calculate the heat loss for a window 0.914 m * 1.83 m.(note: this calculation neglects the effect of the convective coefficient on one outside surface of one side of the window, the convective coefficient on the other outside surface, and convection inside the window.)

Question 1 how do an ionic bond and a covalent bond differ? an ionic bond is an attraction between oppositely charged ions. a covalent bond is a sharing of electrons between atoms. a covalent bond is an attraction between oppositely charged ions. an ionic bond is a sharing of electrons between atoms. there is no difference. both an ionic bond and a covalent bond share electrons. there is no difference. both an ionic bond and a covalent bond are attractions between oppositely charged ions. question 2 what is the definition of a covalent bond? a bond between two positive ions a bond between two negative ions a bond between a positive and a negative ion a bond between two atoms question 3 what is a bond called that shares electrons between two neutral atoms? covalent bond ionic bond metallic bond polar bond question 4 water (h2o) is composed of the same elements as carbon monoxide (co). how do their properties compare? they have different properties because the arrangement of atoms is different. they have the same properties because they have the same atoms. they have different properties because they have different atoms. they have the same properties because they have the same arrangement of atoms. question 5 what is the definition of a chemical bond? a mutual attraction between the nuclei and electrons in two different atoms a mutual attraction between the nuclei and electrons in a single atom a mutual repulsion between the nuclei and electrons in two different atoms a mutual repulsion between the nuclei and electrons in a single atom
