Understand how to represent chemical reactions using an equations Question If two compounds in a chemical reaction are listed with the coefficients 2 and 5 respectively, which is NOT a possible numerical combination of these compounds that will result in their complete reaction? Select the correct answer below: a.4 and 10 b.100 and 250 c.8 and 18 d.40 and 100

8 and 18

Explanation:

This is more math relevant question. lemme try to solve it.

given coefficients: 2 and 5

the relation between 2 and 5 = x and y

x = x ; y = 2x + (x/2)

to see possible numerical combination, we apply one by one all possible combinations in this equation.

1) 4 and 10

x= 4

y =  2x + (x/2)

 = 2 x (4) + (4/2)

 = 8 + 2

y = 10

this numerical combination is possible.

2) 100 and 250

x = 100

y = (2 x 100) + (100/2)

    = 200 + 50

y = 250

This numerical combination is also possible.

4) 40 and 100

x = 40

y = (2 x 40) + (40/2)

 = 80 + 20

y = 100

Given possible combination 40 and 100 is right.

3) 8 and 18

x = 8

y = (2 x 8) + (8/2)

 = 16 + 4

y = 20

so, here given possible combination, 8 and 18 is not right. The right combination will form 8 and 20.

cuz he is really really short, assuming an unorthodox and inherently unlucky configuration of elevator buttons…

explanation:

the answer is: reproductively

i think i spelled it wrong lol

anyways hope i
