Why don’t Noble Gases have a value for electronegativity?

Mathematics
1 answer:
kumpel [21]3 years ago
7 0

Answer:

The answer is 1.

Step-by-step explanation:

Nobel gases have full shell of valence electrons, that is why they tend to not enter any chemical reactions because they are satisfied while metals have very few electrons in the valence shell, so they are active in any chemical reaction.

One can convert temperature from Kelvin into Fahrenheit using the formula F=95(K−273)+32. What is the temperature in Kelvin corr
DiKsa [7]

Answer:

The temperature in Kelvin corresponding to F degrees Fahrenheit is K=\frac{F-32}{95}+273

Step-by-step explanation:

Given : One can convert temperature from Kelvin into Fahrenheit using the formula F=95(K-273)+32.

To find : What is the temperature in Kelvin corresponding to F degrees Fahrenheit?

Solution :

Temperature from Kelvin into Fahrenheit is given by,

F=95(K-273)+32

Writing Kelvin in terms of Fahrenheit,

Subtract 32 both side,

F-32=95(K-273)

Divide by 95 both side,

\frac{F-32}{95}=K-273

Add 273 both side,

\frac{F-32}{95}+273=K

Therefore, The temperature in Kelvin corresponding to F degrees Fahrenheit is K=\frac{F-32}{95}+273

How can I solve this does anyone knows?
Ipatiy [6.2K]
A. C = 17h + 15
b. 83 = 17h + 15 
    -15           - 15  subtract 15 from both sides 
    68 = 17h
    ------------
         17               divide both sides by 17
      4=h  
  They cleaned the house for 4 hours
c. C = 20x
to do this last part, you would put both equations into the calculator under y=, then look at the table to determine when the price is the same. According to the calculator, the price is the same at 5 hours

If θ is an angle in standard position whose terminal side passes through (3, 4), evaluate tan(1/2)θ.
aleksandr82 [10.1K]

The tangent half angle formula, one of several, is

\tan \dfrac a 2 = \dfrac{1 - \cos a}{\sin a}

We have θ is opposite 4 in the 3/4/5 right triangle so

\cos \theta = \dfrac{3}{5}

\sin \theta = \dfrac{4}{5}

\tan \dfrac{\theta}{2} = \dfrac{1 - 3/5}{4/5} = \dfrac{5-3}{4}=\dfrac{1}{2}

Answer: 1/2

This is actually pretty deep.  It says half the big acute angle in the 3/4/5 triangle is the small diagonal angle of the 1x2 rectangle.   Similarly, the small acute angle in 3/4/5 triangle is twice the small diagonal angle of the 1x3 rectangle.
