IUPAC nomenclature of structure 1 is 5-bromo-3-ethyl-2,2-dimethylhexane and for structure 2 it is 1,1,4-trimethyl-3 -(1-methylethyl)cyclohexane
IUPAC nomenclature is based on naming a molecule's longest chain of carbons connected by single bonds, whether in a continuous chain or in a ring. All deviations, either multiple bonds or atoms other than carbon and hydrogen, are indicated by prefixes or suffixes according to a specific set of priorities
In structure 1 the longest chain was found to be a 6 carbon chain and the numbering started from the side where it is highly substituted. Hence the name is 5-bromo-3-ethyl-2,2-dimethylhexane
In structure 2 we have a cyclic structure and so the numbering will be done in such a way that all the substituent gets the least numbering hence the name of the compound will be 1,1,4-trimethyl-3 -(1-methylethyl)cyclohexane

Which example involves the transformation of chemical enegy directly to light energy?
1.A glow stick
2.Photosynthesis
3.Windmill
4.A hydroelectric dam
Answers
A glow stick is an example of a device that directly converts chemical energy into light energy.
A) A glow stick generates luminance, or light energy, using chemical energy from the compounds contained within it. When the stick is broken or twisted, the chemicals inside it are released and, through a chemical reaction, chemical energy is transformed into light energy.
B) plants employ light energy during photosynthesis to create oxygen and energy in the form of sugar (glucose).
C) The wind serves as the energy source for a windmill, and when the rotor blades revolve, the wind energy is transformed into mechanical energy. Then, electrical energy is created from that mechanical energy. The light energy produced by these electrical currents is subsequently employed in lamps. As a result, the chemical energy is not changed directly.
D) Water provides mechanical energy to a hydroelectric dam. When the water reaches the turbine, the gravitational potential energy that it had because of its height is transformed into kinetic energy. Then electrical energy is created from this kinetic energy.
Therefore, Glow Stick is the sole example where chemical energy is transformed into light energy in this manner.

state any three properties that can be used to classify elements
Answers
Answer:
The elements on the Periodic Table have been organized into groupings based on the chemical and reactive properties of the elements. The three major groups are the metals, nonmetals, and metalloids. The metals towards the left and lower parts of the Table tend to give up electrons in chemical bonding. The nonmetals to the right and upper parts of the Table tend to accept electrons in chemical bonding. The metalloids some say have an identity crisis and are a band of elements in between the metals and nonmetals which can show characteristics of the bordering groups depending on the type of bonding or chemical reaction. This group is also the foundation of our semiconductor, integrated circuit industries.Other groupings of the elements are into "families" based on the chemical nature of the elements. Some of these are the alkali metals, alkaline earth metals, transition metals, chalcogens, halogens, and inert/noble gases. There is also a semi-grouping of elements above atomic number 83 as these tend to be unstable and show natural radioactivity. Additionally, one could group the elements based on their physical states at room temperatures, such as solids, liquids, and gases.
In all both, chemical and physical properties are used to classify and group elements into useful associative collections based on these attributes. It simply depends on the purpose for the classification.

water dissolves salts because it: select one: a. is hydrophobic, and salts are also hydrophobic. b. forms covalent bonds with the atoms of the salt crystal. c. has partial positive and negative charges. d. evaporates quickly at room temperature.
Answers
Salts get dissolved in water because it has partial positive and negative charges. So option (c) is correct.
Why does salt dissolves in water?The water molecules pull the Na and Cl ions apart while breaking the ionic bond which held them together. After the salt ions are pulled apart, they get surrounded by water molecules. The salt dissolves to form a homogeneous solution.
The slightly positive portion of sodium is attracted to the slightly negative portion of oxygen on the water molecule. At the same time, the slightly electronegative chlorine moieties of NaCl are attracted to the slightly electropositive hydrogen moieties of water.In either case, no true bond is formed, the stronger covalent bonds of water (also commonly held by hydrogen bonds between water molecules) win, NaCl gets pulled apart, resulting in dissociation of Na+ and Cl- ions with the Na+ and Cl- ions setting loosely in place between the intact H₂O molecules. NaCl is then dissolved.Salts are ionic and are expected to dissolve in water because water itself is polar. Therefore, ionic salts are expected to dissolve in polar solvents.

What is a covalent bond?
The exchange of one or more pairs of electrons between two atoms forms a covalent connection. The two atomic nuclei are drawing these electrons in unison. When there is insufficient space between two atoms' electronegativities for an electron transfer to take place and create ions, a covalent bond is formed. Bonding electrons are shared electrons that are present in the region between the two nuclei. The bound pair serves as the "glue" that binds the atoms in molecular structures.
The only covalently bound substance that is the simplest is a hydrogen molecule. Two hydrogen atoms with one electron in each's 1s orbital make up the compound.

On adding more CO2 equilibrium shifts to left, adding more oxygen the equilibrium shift to right, increasing a temperature will shift the equilibrium to left and adding the catalyst will not affect the equilibrium.
According to Heisenberg Uncertainty Principle, if the equilibrium of a system of reaction is disturbed by making any changes in the property the reaction will shift into that direction by itself that stabilizes the equilibrium again.
According to the reaction,
CH4O + O2 = H2O + CO2 + Heat
a. Adding more CO₂ will shift the reaction towards the left side or we can say that adding carbon dioxide into the system will shift the reaction towards the reactant side. Because the concentration of carbon dioxide on the product side has increased, the equilibrium is disturbed so in order to stabilize the equilibrium again the reaction will shift towards the reactant side.
b. Adding more oxygen means that we are adding more amount of reactants which disturbs the equilibrium of the reaction so to stabilize the equilibrium again the reaction will shift towards the product side.
