Which would you predict to have a higher melting point, SiO2 or CO2? Why? Please list the actual melting point values. Did your prediction agree Yes or No?

From the position of the element indium in the Periodic Table, predict the formula of its highest valency normal oxide. Select an answer from the list below. Select one: In2O3 InO₂ InO3 In205 InO Indium in your answer has a valency of 5. this is incorrect

Please don't provide handwritten solution ....

QUESTION 5 "Place the following three choices in order of increasing melting point. Some of the examples can have multiple isomers. Do not look up values, instead use the rules you have been taught in this course Ar He Xe" Ar< He < Xe He< Ar< Xe He < Xe < Ar Ar < Xe < He Xe < Ar< He QUESTION 6 Place the following three choices in order of increasing viscosity. C 7H 16 H ₂0 C 6H 14 C7H16
