Answer:

Anion ( F^-)

Explanation:

An anion is formed when a non metal receives an electron from metallic atom.

Fluorine atom has electronic configuration of 1S2 2S2 2P5. It therefore needs 1 electron to attain the noble gas configuration. Thus to do this, fluorine will receive 1 electron from metallic atom to form fluoride ion(F^-) with electronic configuration as 1s2 2s2 2p6 and thus forming ionic bond.

This can be seen when sodium react with fluorine to form sodium fluoride according to the equation

1. Na —> Na+ + e-

2. F + e- —> F-

Combining 1 and 2, we have:

Na + F + e- —> Na+ + F- + e-

Na + F —> Na+F-

The above illustration indicates ionic bonding as electron was transferred from the sodium atom to the fluorine atom, thus forming sodium ion (Na+) and fluorine ion(F-)

Answer:

An anion

Explanation:

An ion of flourine wife form an anion. What is an anion? An anion is a negatively charged atom.It occurs as a result of gain of electron by an atom to stabilize it's octet structure.

This is a common phenomenon for non metals and halogens are a good example of that which are strongly electronegative with electronic configuration of 2,7......

When elemental iron corrodes it combines with oxygen in the air to ultimately form red brown iron(iii) oxide which we call rust.
iren [92.7K]
<span>The mass of the nail would increase, because the iron is adding oxygen to its chemical composition. This would increase the overall mass. If the mass increases from 23.2g to 24.1g, then the increase would be the difference between the two masses, or 0.9g.</span>

Which of the following does not influence the effectiveness of a detergent? A-air temperature B-water temperature C-energy appli
Natasha2012 [34]

<em> A-air temperature does not influence the effectiveness of a detergent</em>

\boxed{\boxed{\bold{Further~explanation}}}

In chemical reactions several factors influence among others:

1. Temperature

The temperature of the reaction that is raised will cause the particles to move more actively so that collisions between particles will become more frequent so that the speed of chemical reactions will be greater

2. Pressure

Addition of pressure will increase the concentration because the volume is reduced, a greater concentration will accelerate the reaction

3. Concentration / substance level

The greater the level, the more substances dissolved and involved in the reaction, thereby increasing the speed of the reaction

4. Stirring

The mechanical force applied to the solution that reacts will cause more collisions to accelerate the reaction

5 Catalysts

Addition of a catalyst to accelerate the reaction without reaction with reactant substances

Detergents are used as cleaning removers of dirt on clothes or oily/fatty items

The main structure of detergent is surfactant which has hydrophobic (binding fat) and hydrophilic (which binds water) parts

Surfactants also function to reduce water surface tension so that it is easier to bind dirt

Surfactants can be anionic in which there are derivatives of Benzene, namely: Alkyl Benzene Sulfonate obtained from sulfonation reactions where hydrogen in benzene is substituted by sulfonate groups (HSO₃⁻) reaction with sulfuric acid (H₂SO₄)

If we see the answer choices:

A. Air temperature

Air does not play a role in the reaction or cleaning process of dirt by detergents, so it is not an effective or ineffective factor in detergent cleaning

B. Water temperature

The right water temperature by adjusting the conditions of clothing materials will increase the effectiveness of detergents, for example, hot temperatures suitable for lifting oil/oil stains, warm/cold temperatures for clothes that are not too dirty and made of silk/wool

C. Energy gave

The energy in the cleaning process can be done through mechanical energy so that the collision between the particles of detergent and dirt will occur more so that faster removal of dirt

D. the length and frequency of the treatment

Sufficient time and the frequency of contact between detergents and ingredients, especially for dirty and hard-to-lose materials, will make removal of dirt better
