Question

2. If a reaction is endothermic, the energy will release. T/F 3. Molecular compounds are made up of metals and non-metals. T/F 4. lonic compounds tend to be highly ionic. T/F 5. A triple bond consists of six electrons. T/F 6. Metal component names appear to the right in compound names. T/F 7. Which of the following molecular shapes has both water and H2S? (A) linear (B) bent (C) tetrahedral 8. Zinc oxide and titanium dioxide are effective sunscreens because they are. (A) transparent, (B) so opaque.

Answer 1

2) False A reaction is said to be endothermic if energy is absosbed. 3) False A mole cular compoundle foum when elements Share electrons in a covalent bonel to form mobiles Tonic compounds are formeel when metals react with non-mebal. 4) False. Ionic compound can be bolh hippy highly and poorly Ionic. It is based on the difference of electronegativity more the difference more conic is the compound. 57 True Triple bond is formed when 6 electrons are Shared between two atome. Ex: NEN by False Compound an names has metal component first Ex: calcium phosphate a Iron (1) onide etc.

77 Bent H₂S H₂O St H Hs 104.5 s bond angle Crame) 8) Transperent. They are effective because the particle size is very small to reflect visible light. So, they actually form a invisible layer Ctransperent) to protect from UV rays.
