Concept explainers
(a)
Interpretation: The Lewis dot structure of element He (2) needs to be determined.
Concept Introduction: The group number of main-group elements is equal to the number of valence electrons present in that element. The Lewis dot structure is drawn using the symbol of an atom and number of valence electrons present in it.
(b)
Interpretation: The Lewis dot structure of element Na (11) needs to be determined.
Concept Introduction: The group number of main-group elements is equal to the number of valence electrons present in that element. The Lewis dot structure is drawn using the symbol of an atom and number of valence electrons present in it.
(c)
Interpretation: The Lewis dot structure of element Cl (17) needs to be determined.
Concept Introduction: The group number of main-group elements is equal to the number of valence electrons present in that element. The Lewis dot structure is drawn using the symbol of an atom and number of valence electrons present in it.
(d)
Interpretation: The Lewis dot structure of element P (15) needs to be determined.
Concept Introduction:The group number of main-group elements is equal to the number of valence electrons present in that element. The Lewis dot structure is drawn using the symbol of an atom and number of valence electrons present in it.
(e)
Interpretation: The Lewis dot structure of element H (1) needs to be determined.
Concept Introduction: The group number of main-group elements is equal to the number of valence electrons present in that element. The Lewis dot structure is drawn using the symbol of an atom and number of valence electrons present in it.

- Fill-in-the molecules for the oxidation or reduction of the starting alcohol.arrow_forwardName the following carbohydrates give both the systematic and common names. Don't forget to identify the Isomer.arrow_forwardWhat is the product of the reaction of XeF4 with H2O? Group of answer choices H2XeF2 H2XeF4 XeO3 H2XeOarrow_forward
- While noble gas exerts the strongest London (dispersion) forces on neighboring atoms? Group of answer choices Xe Ar Kr Nearrow_forwardWhich of the following elements is corrosive to your skin due to that element breaking down C=C bonds? Group of answer choices fluorine iodine bromine chlorinearrow_forwardWhat the best source of sulfide to use on a small scale in the lab? Group of answer choices thiourea H2S NaHS Na2Sarrow_forward
- Which of the following statements about sulfur is FALSE? Group of answer choices H2S is the product of an oxygen-depleted ecosystem. In the acid mine drainage reaction, FeS2 is a product. One allotrope of sulfur has the formula S20. In the environment, bacterial oxidation can convert S2− to elemental S or SO42−.arrow_forwardOf the following choices, which is the best reason that most materials DON'T spontaneously combust even though our atmosphere is about 21% oxygen? Group of answer choices The reduction of O2 in the gas phase (O2 + e− → O2−) is spontaneous. The reduction of O2 in acid solution (O2 + H+ + e− → HO2(aq)) is spontaneous. O2 is not a reactant in combustion. The O2 bond dissociation energy is 494 kJ/mol, leading to a high activation energy for combustion.arrow_forwardplease answer in the scope of the SCH4U course, I am having a hard time understanding, may you show all steps please and thank you! can you also put the final answers in the table so its understandablearrow_forward
