Electronegativity is defined as a measure of the tendency of atoms to attract electrons in a chemical bond.

Calculate the initial rate for the formation of c at 25 ∘c, if [a]=0.50m and [b]=0.075m

Alenkinab [10]

Rate = k * [A]^2 * [B]^1

Use the data from any trial to calculate k. 

k = (rate)/([A]^2 * [B]^1) 

E.g., for Trial 1, we have 

rate = 3.0×10−3 M/s 
[A] = 0.50 M 
[B] = 0.010 M 

Plug those numbers in and crank out the answer. 

Now with the calculated value of k, calculate the initial rate for [A] = 0.50 M and [B] = 0.075 M 

rate = k * [A]^2 * [B]^1 

k = calculated value 
[A] = 0.50 M 
[B] = 0.075 M

A six row combin harvests 266 pounds of corn per min. How many bushels of corn does it harvest per hour? (Note: 1 Bu = 56 Lbs) R

kiruha [24]

Answer:

The six-row combin harvests 285 bushels of corn per hour.

Explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three.

If the relationship between the magnitudes is direct, you can apply the following formula:

a ⇒ b

c ⇒ x

So: $x=\frac{a*b}{c}$

In this case you can apply it in the following way: if 56 pounds is equal to 1 bushel, 266 pounds to how many bushels is it?

$x=\frac{266 pounds*1 bushel}{56 pounds}$

x=4.75

This is, a six row combin harvests 4.75 bushels of corn per min.

So, being 1 hour equal to 60 minutes, you can apply the following rule of three: if in 1 minute a six-row harvester harvests , in 60 minutes how many bushels of corn it harvests?

$bushels of corn=\frac{60 minutes*4.75 bushels of corn}{1minute}$
