Review the types of elements that create ionic bonds as

Chemistry

777dan777 [17]3 years ago
7 0

Answer:

N2 Covalent

CCl4 Covalent

SiO2 Covalent

AlCl3 Covalent

CaCl2 Ionic

LiBr Covalent

Explanation:

With covalent bonds, there is a sharing of electron pairs between the atoms.

With ionic bonds, there is complete transfer of valence electrons between atoms. Formed by the interaction of a metal with a non-metal.

Where:

Electrons aren't transferred in covalent bonds.

Protons aren't  transferred in covalent bonds

Protons aren't shared in covalent bonds

N3-

C4+

Cl-

Si4+ = Metal

O2- = Non-metal

Al3+ = Metal

Li+ = Metal

Ca2+ = Metal

Br  1-, 1+, 5+ = Halogen

N2 = N3- and N3- Covalent

CCl4 = C4+ and Cl- x4 Covalent

SiO2 = Si4+ and O2- x 2 Metal with non metal Covalent

AlCl3 = Al3+ and Cl- x 3 Covalent Though this one is complex as to why because it seems like it should be ionic

CaCl2 = Ca2+ and Cl- x 2 Metal with non-metal Ionic

LiBr = Li+ and Br- Covalent as neither is a non-metal

In a food chain, energy does NOT flow directly from - F producer to decomposer G producer to consumer H consumer to decomposer J
IgorLugansk [536]

Answer:

producer to decomposer

Explanation:

This is because in a food chain , energy flow from one trophic level to another. The producer which include plants are the source of energy which they manufacture good in the presence of light energy from sun. Energy flow directly from the producer to the primary consumer which are heterotrophs that feed on plants. Energy flow from consumer to decomposer after the consumer died and it is decayed.

6 At STP, which element is a good conductor of electricity?(1) chlorine (3) silver
alexgriva [62]
For an object to conduct electricity it should have free or delocalised electrons that are free to pass the charge and hence take part in conducting electricity.
From the given choices
Chlorine is a halogen existing as a diatomic gas. Iodine too is a halogen and 2 Iodine atoms held together by covalent bond. Cl - Cl bonds and I-I bonds are  covalent bonds. the outer electrons of Cl and I take part in covalent bonds therefore they are fixed and not free to move about. therefore no free electrons to conduct electricity.
Sulfur is a solid that too is held together by covalent bonds so it does not have free electrons to conduct electricity.

Silver is a metal and a general property of metals are their ability to conduct electricity.
metal structure are metal ions tightly packed together. when the metal atoms are tightly packed their valence electrons are removed and delocalised. Positively charged metal ions are embedded in a sea of delocalised electrons.
therefore there are delocalised electrons that can conduct electricity 


answer is 3) silver

Select the true statements regarding these resonance structures of formate.? Each carbon-oyxgen bond is somewhere between a sing
son4ous [18]

Answer : Option 1) The true statement is each carbon-oxygen bond is somewhere between a single and double bond and the actual structure of format is an average of the two resonance forms.

Explanation : The actual structure of formate is found to be a resonance hybrid of the two resonating forms. The actual structure for formate do not switches back and forth between two resonance forms.

The O atom in the formate molecule with one bond and three lone pairs, in the resonance form left with reference to the attached image, gets changed into O atom with two bonds and two lone pairs.

Again, the O atom with two bonds and two lone pairs on the resonance form left, changed into O atom with one bond and three lone pairs. It concludes that each carbon-oxygen bond is neither a single bond nor a double bond; each carbon-oxygen bond is somewhere between a single and double bond.

Also, it is seen that each oxygen atom does not have neither a double bond nor a single bond 50% of the time.
