Answer:

The sulfur S and fluorine F elements will form negative ions.

Explanation:

Ions are molecules that have gained or lost an electric charge. Therefore, they can be positive (loss of electrons) or negative (they have gained electrons), also called cations or anions, respectively.

So negative ions are negatively charged particles that are also called electrons. The elements or particles will gain electrons in order to complete the valence electron octet.

In groups 15 to 17, the charge is generally negative because these elements are more likely to gain electrons than to lose them, thereby reaching a full octet of eight valence electrons.

In this case, <u><em>the elements sulfur S and fluorine F belong to group 16 and 17 respectively. Then these will form negative ions.</em></u>

Answer:

Good Question

see Negative ions are those which gain electrons to attain stability

Now, We know All metals tend to donate electrons which inturn results in positive charge

Now Have a closer look at options

a) F

It is fluorine

it's configuration is 2,7

that means it requires one electron to complete it's octet from 7 to 8

therefore, it will gain one electron which results in

{f }^{ - }

b)Li

lithium is metal having one electron in outermost shell So it will rather loose electron to attain stability

c)Ne

Neon is Noble gas which exists in neutral stare

d)S

Sulphur needs 2 more electrons to attain stability

therefore it exists as negative ion

e)Al

Aluminum is metal So it exists as positive ion

f)Be also exists as positive ion

____________ use cleaning solutions that eventually become spent and must be disposed of properly.
Elanso [62]

The answer is- Part washers use cleaning solutions that eventually become spent and must be disposed of properly.

Cleaning solutions: Cleaning solution is a liquid solvent or solution used to clean the working surfaces and the parts of a machine.

What type of cleaning solution is Part washers?

  • Parts washers are mechanical devices that are designed to be cleaned to remove debris, dirt, oil, paint, and other substances that could potentially contaminate parts to prepare them for assembly, packaging, or even painting.
  • They are basically used to clean parts to make them ready for functional use.
  • Cleaning solutions for washing used parts are considered a special waste because they can be hazardous waste and are waste from an industrial process.
  • Used solvents are almost always hazardous waste. Both solvent and aqueous parts washers produce a sludge that is usually hazardous because it contains toxic metals and solvents from the parts being cleaned.
  • Absorbents used to wipe parts after washing are also dangerous if they contain toxic metals in concentrations exceeding regulatory limits or listed hazardous solvents, and used oil may also contain hazardous waste.
  • Thus, these cleaning solutions must be disposed of properly.

An ice cream company decides to make a new lower calorie flavor,but testers reported that the flavor wasnt as good as the origin
IgorLugansk [536]

Answer:

Yes, the given instance is an example of a trade-off.

Explanation:

  • The trade-off seems to be a strategy to minimize or surrender one or more favorable results in consideration for increasing either receiving other favorable results to optimize cumulative benefit or efficacy within such conditions.
  • The above is indeed a trade-off since the participants are experimenting in exchange again for ice cream individuals have to enjoy. The ice cream manufacturer always gets a review of the technician in exchange for free ice cream.

Lubov Fominskaja [6]

Answer:

C )

Explanation:

Controlled scientific experiment tests scientific assumption (hypothesis), under controlled conditions.

In controlled scientific experiment, alters the test variable (independent variable) and observes the effects on the outcome variable (dependent variable).

Eg : Studying impact of sunlight on plant's group, where former independent variable is altered & its effects on dependent outcome variable is observed.
