Q: Q: Hybrid orbitals are formed only in which type of bonded atoms? Read this paragraph and choose the correct option from the provided answers: The following ideas are important in understanding hybridization: 1. Hybrid orbitals do not exist in isolated atoms. They are formed only in covalently bonded atoms. Hybrid orbitals have shapes and orientations that are very different from those of the atomic orbitals in isolated. Choices: - ionically - partially - thermally - covalently A:
A: covalently

Q: Q: All alkanes are composed of carbon and hydrogen atoms, and have similar bonds, structures, and formulas; noncyclic alkanes all have a formula of cnh2n+2. the number of carbon atoms present in an alkane has what? Read this paragraph and choose the correct option from the provided answers: All alkanes are composed of carbon and hydrogen atoms, and have similar bonds, structures, and formulas; noncyclic alkanes all have a formula of CnH2n+2. The number of carbon atoms present in an alkane has no limit. Greater numbers of atoms in the molecules will lead to stronger intermolecular attractions (dispersion forces) and correspondingly different physical properties of the molecules. Properties such as melting point and boiling point (Table 20.1) usually change smoothly and predictably as the number of carbon and hydrogen atoms in the molecules change. Properties of Some Alkanes[3] Alkane. Choices: - done limit - crippling limit - such limit - no limit A:
A: no limit

Q: Q: Co 2 , h 2 o, methane, o 3 , nitrous oxides (no and no 2 ), and chlorofluorocarbons (cfcs) are known as what type of gases? Read this paragraph and choose the correct option from the provided answers: Greenhouse gases include CO 2 , H 2 O, methane, O 3 , nitrous oxides (NO and NO 2 ), and chlorofluorocarbons (CFCs). All are a normal part of the atmosphere except CFCs. The table below shows how each greenhouse gas naturally enters the atmosphere ( Table below ). Choices: - chemical gases - hydrogen gases - carbonate gases - greenhouse gases A:
A: greenhouse gases

Q: Q: What are drilled to monitor groundwater pollution? Read this paragraph and choose the correct option from the provided answers: Test wells are drilled to monitor groundwater pollution. Choices: - sewers - aquifers - draining wells - test wells A:
A: test wells
