Answer:

The answer.

Explanation:

Group 17 consists of Halogens, and group 18 consists of Noble Gases.

Group 17 are very high electronegativities. They have seven valence electrons. They are highly reactive, especially with alkali metals and alkaline earth.  

In group 18 their elements are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable.

Nobel gases are placed there because they are extremely unreactive.

Halogen elements are placed there because they have seven valence electrons, they only require one additional electron to form a full octet.

How can a piece of wood floating on water illustrate the condition of lowest potential energy and maximum
drek231 [11]

Answer:

By minimizing the height of the body's center of gravity relative to its center of buoyancy

Explanation:

In hydrostatics, the equilibrium state of a floating body relates to either a maximum or minimum of the potential energy.An equilibrium is stable when the potential energy is minimum.Minimizing the height of the floating body's center of gravity relative to its center of buoyancy attains a stable equilibrium configuration.

If a decrease in temperature accompanies a reaction, what occurred?
Sliva [168]

Answer:

Energy was released

Explanation:

Decrease in temperature means less energy, but the energy had to have been transferred because energy can't be destroyed or created. So if the temp. went down, energy must have been lost. (If it had been absorbed, the temp. would have gone up)

If 7.35 L of gas at 17°C and 3.55 atm is compressed at a pressure of 123 atm and 34°C, calculate the
MaRussiya [10]

Answer: V2= 0.224L

Explanation:

P1=3.55atm, V2= 7.35L, T1= 290, P2= 123atm, V2=?, T2= 307K

Applying general gas equation

P1V1/T1= P2V2/T2

Substitute and Simplify

3.55×7.35/290 = 123×V2/307

V2= 0.224L
