Answer:

The lowest whole number ratio of the elements in a compound is called <u><em>the empirical formula.</em></u>

Step-by-step explanation:

A molecular formula consists of the chemical symbols of the constituent elements of a compound followed by numerical subscripts that describe the number of atoms of each element present in the molecule.

Then, the representation of the elements that form a compound and the proportion in which they are found, or the number of atoms that form a molecule is called the chemical formula.

The empirical formula is an expression that represents the simplest proportion in which atoms that form a chemical compound are present. It is then the simplest representation of a compound. Therefore, it is called the minimum formula.

In summary, the empirical formula is a formula that indicates the simplest integer ratio of all atoms in a molecule.

Finally, <u><em>the lowest whole number ratio of the elements in a compound is called the empirical formula.</em></u>

Need help! Will brainiest if right!
tangare [24]

Answer:

Y=3x+5

Step-by-step explanation:

If we take x = 1, according to the first function (the answer) y would be 8.

Other options:

—————

Formula 3:

Y= 2^x+5 == 7

Formula 4:

Y = x+8 == 9

True answer = 10.

——————

Ok, so the last one seems more accurate lets test the first and last one on two more numbers:

——————

X = 15

Formula 1:

50

Formula 4:

23

True answer = 60.

The first formula wins.

————————-

X= 10

Formula 1:

35

Formula 4:

18

True answer = 41

The first formula wins.

——————

So, we can see that the first formula is most accurate.

Consider the following theorem and proof.Theorem: The number âš2 is not rational number.Proof: Let's suppose âš2 is a rational n
ololo11 [35]

Answer:

The statement "Both of the numbers a and b cannot be even." is justified by the fact that a/b is simplified lowest terms

Step-by-step explanation:

We need to  show that the √2 is an irrational number.

And from the given steps of proof stated in the question, we need to find the assumption that justifies the fact : " Both of the number a and b cannot be even".

First take the given options :

Option a : √2 is a rational number

√2 being an rational or irrational has no relation of a and b to be even or odd. So, this option is rejected.

Option B : a/b is simplified lowest terms

This shows that a and b are not even because if a and b are even then a/b can be simplified in other lowest term.

Option c : √2 is a irrational number

Similarly, By using the inverse part of Option A, option c is also rejected.

Option d : The fact that b divides a evenly

This only shows that the a is even. This does not give any idea about b is even or not. So option D is also rejected.

Option E : The fact that a and b are whole numbers

This fact does not imply that the a and b are even or odd. So option E is also rejected.

Hence, The statement "Both of the numbers a and b cannot be even." is justified by the fact that a/b is simplified lowest terms
