Answer : The number of electrons present in the 5th shell are, 50.

Explanation :

As we know that the electrons are filled in the electrons shell of an atom from lower energy shells to the higher energy shells. Each shell contains fixed number of electrons that means 1st shell contains 2 electrons, 2nd shell contains 8 (2+6) electrons, 3rd shell contains 18 (2+6+10) electrons and so on.

The general formula of for the 'nth' shell will be : 2n^2. Where 'n' is the number of shell.

As we are given that the number of shell is, 5th

So, the number of electrons present in 5th shell are = 2n^2=2\times (5)^2=2\times 25=50

Hence, the number of electrons present in the 5th shell are, 50.

Each shell contains a fixed number of electrons. The general formula of the number of electrons can be hold in n-th shell is 2n². 5th shell can hold 2x5² = 50  number of electrons.

1st shell contains 2 X 1²= 2 number of electrons, 2nd shell contains 2 X 2²=8 number of electrons, 3rd shell contains 2 X 3²=18 number of electrons, 4th shell contains 2 X 4²=32 number of electrons,  5th shell contains 2 X 5²=50 number of electrons and so on.

“If you start with a faster forward reaction, you will end up with more __________.”
Finger [1]

Answer:

time to do another things !

Explanation:

Here we can not fill in the blank the words like: products, because in many cases, a slower forward reaction can give the better quantity of products.

We can not say that a faster forward reaction gives the products with better quality, because it depend on what are the reactions we mention about.

Personally, I think this is the answer for this question.

It seems that something is missing in this question.

Table salt contains 39.33 g of sodium per 100 g of salt. The U.S. Food and Drug Administration (FDA) recommends that adults cons
IrinaVladis [17]
 <span>First set up the equation 39.33g/100g = x/1.28g and that'll give you how much sodium is in each 100g of the mix. 

39.33g *1.28g= 100g * x 
x = 0.503424g 
x = Amount of sodium per 100g of the mix 

Now 2.4g / 0.503424 = 4.7674 
Multiply by 100 and you get 476.7353g</span>
