Which statement about bonding is correct? (1 point)

Chemistry
2 answers:
ZanzabumX [31]2 years ago
7 0

The statement correct about bonding is the release of energy in bond formation, and is exothermic. Thus, option C is correct.

The bonds have been defined as the sharing of electrons between atoms for the stabilization and forming compounds. The formation and breaking of the bond results in the absorption and release of the energy.

<h3>Endothermic and Exothermic reaction</h3>

The reaction in which the energy has been released has been termed as exothermic reaction. The reaction in which energy is absorbed is termed as endothermic system.

The bonds are stable, and to break the bond energy has to be provided to the system. The energy will result in the delocalization of electrons and thereby breaking of bonds.

Since energy has been absorbed by the system during breaking of bonds, the reaction has been an endothermic reaction.

The formation of the bond has been releases the energy in the system and is an exothermic reaction. Thus, option C is correct.

An ion of oxygen- 16 contains 8 protons and has a 2- charge. How many electrons does it have?
Verdich [7]

Answer:

i would say 10, so the anser is A.

Explanation:

because there are the same number of protons and electrons, therefore for a regular O, you are supposed to have only 8 protons, but it is charged, thus, whatever the charge is will be taken into consideration into how much the proton and electron doe it have. Thus, for this case, it has 10, because the charge is negative and you have 8 electron plus 2 = 10.

Grease is applied to the moving part of machine. <br>​
RideAnS [48]

Answer:

Explanation:

The moving part won't move on its own there's a force but the force isn't enough for something like a bike chain it need grease to move smoothly or else it will just be super stuck or slow.

A solution is a homogenous mixture of solute and solvent. There are different types of solutions. A carbonated drink is an examp
goblinko [34]

Answer:

  • A.) Gases are readily soluble in water at higher temperatures: FALSE
  • B.) Carbon dioxide gas will be less soluble in water when the partial pressure is low: TRUE
  • C.) Zinc sulfate is soluble in water: TRUE
  • D.) Propanol and heptane are miscible: FALSE
  • E.) Table salt dissolves in water to form a solution: TRUE

Explanation:

The answer choices are:

  • A.) Gases are readily soluble in water at higher temperatures.
  • B.) Carbon dioxide gas will be less soluble in water when the partial pressure is low.
  • C.) Zinc sulfate is soluble in water.
  • D.) Propanol and heptane are miscible.
  • E.) Table salt dissolves in water to form a solution.

<h2>Solution</h2>

Let's see every statement

<u><em>A.) Gases are readily soluble in water at higher temperatures.</em></u>

This is false. At higher temperature, the gas molecules will have higher kinetic energy, meaning that they will move faster and escape more easily from the liquid phase. Thus, gases are less soluble at higher temperatures.

<u><em>B.) Carbon dioxide gas will be less soluble in water when the partial pressure is low.</em></u>

This is TRUE.

HIgher pressures "push" the gas molecules into the liquid phase. When more molecules get dissolved the pressure is partially relieved.

This relation is stated by Henry's Law: the solubility of gases in liquids is directly proportional to the pressure of the gases above the surface of the solution. Thus, carbon dioxide will me less soluble in water when the pressure is low.

<u><em>C.) Zinc sulfate is soluble in water.</em></u>

This is TRUE.

You must resort to the rules of solubility or search the properties of this salt.

Th solubility rules state that most sulfates are soluble in water. Exceptions are sulfates of Ag⁺,Ca²⁺, Sr²⁺, Ba²⁺, Hg²⁺, and Pb²⁺. Thus, you can expect that zinc sulfate is soluble in water.

<u><em>D.) Propanol and heptane are miscible.</em></u>

This is false.

Propanol is a polar compound. It is miscible with water because water is polar too. Heptane is not polar. Thus, following the rule that "like dissolves like" propanol and heptane are not miscible.

<u><em></em></u>

<u><em>E.) Table salt dissolves in water to form a solution.</em></u>

This is TRUE.

This is a classical example of an ionic compound (sodium chloride) that is soluble in water (a polar solvent), showing the rule that polar solvents dissolve polar and ionic compounds.

It is also an everyday fact: rice, for instance, absorbs salt from water because the salt is dissolved in the water.

Based on these ideas, what are the pro's and con's for both Sexual Reproduction and Asexual reproduction?
Svetradugi [14.3K]
Asexual
Pro:
1. inexpensive to make offspring (usually make a lot at a time and not invest a lot of time in raising them).
2. Do not need a mate to reproduce.
3. Can rapidly expand a population
Con:
1. genetically identical- prone to extinction because once a parasite has evolved to attack a specific genotype, it can kill them all.
2. Lineages usually don't last longer than a couple thousand years

Sexual:
Pros:
1. Genetically unique- so more likely to create a "successful" offspring
2. Lineages more likely to last hundreds of thousands of years

Cons:
1. More effort into creating offspring- require more parental effort
2. STD's- easily to pass
3. need to find a mate or else won't be successful as an organism.

Hope this helps you.
