Answer. Methane molecule is made up of five atoms; four of hydrogen and one of carbon. Carbon atom is sharing its 4 valence electrons with 4 hydrogen atoms each having 1 electron.

Explanation:

Dalton model of atom said that the matter is made up of smallest indivisible particle that is an atom. From which he predicted that methane molecule will be made up one carbon atom and 4 hydrogen atoms.

Quantum model of atom described the structure of atom with the help of four quantum numbers. These number explained the position, magnetic character and spin of electrons  inside the atom. and further explained the sharing of electron between one one carbon and 4 hydrogen atoms.

Hence from these two models we can predict that methane molecule is made up atoms with sharing of electrons.

What conclusions can you draw about how temperature and salinity affect the flow of water? Write an evidence-based claim.
S_A_V [24]

Temperature and salinity changes the density of water.

<h3>Effect of Temperature and salinity on water</h3>

Temperature and salinity directly affect density of water. Water that low temperature is more denser than water that has high temperature while on the other hand, Freshwater which has no salt is less denser than seawater which has more salt concentration so we can conclude that temperature and salinity changes the density of water.

Draw the other possible resonance structure of each organic ion. In each case, draw the structure that minimizes formal charges.
pshichka [43]

Three resonance structures  can be drawn for the allyl cation while two resonance structures can be drawn for the amidate ion.

Sometimes, we cannot fully describe the bonding in a chemical specie using a single chemical structure. In such cases, we have to use a number of structures which cooperatively represent the actual bonding in the molecule. These structures are called resonance or canonical structures.

The resonance structures of the allyl cation and the amidate ion are shown in the images attached to this answer. These structures show the different bonding extremes in these organic ions.

For each of the following compounds, identify what type of bonding holds them together.
svet-max [94.6K]

Explanation

NaCl:  Ionic crystal lattice forces

Hg:   Metallic bonding

CO₂:  London dispersion forces

CH₄:  London dispersion forces

Li₂O:  Ionic crystal lattice forces

Ag:  Metallic bonds

Ionic crystal lattice forces are strong electrostatic force of attraction between oppositely charged ions arranged into a crystal lattice of ionic compound. NaCl and Li₂O are ionic compounds

London dispersion forces holds the molecules of carbon dioxide and methane. They are weak attractions found between non-polar (and polar) molecules.

Metallic bonds exists between Mercury and Gold atoms. This is due to sea of electrons present.
