Select the simplest mole ratio for each substance. Glucose (C6H12O6): Sulfuric acid (H2SO4): Butene (C4H8):
Rom4ik [11]

<u>Answer:</u>

1. In Glucose: C : H : O = 1 : 2 : 1

2. In Sulfuric acid: H : S : O = 2 : 1 : 4

3. In Butene: C : H = 1 : 2

<u>Explanation:</u>

Mole ratio is defined as the ratio of amounts in moles present in a compound. Simplest mole ratio basically means that the moles are present in the least whole number ratio.

  • In Glucose, (C_6H_{12}O_6)

Moles of Carbon atom = 6

Moles of Hydrogen atom = 12

Moles of Oxygen atom = 6

Mole ratio of the atoms: C : H : O :: 6 : 12 : 6

Making this, the simplest mole ratio C : H : O = 1 : 2 : 1

  • In Sulfuric acid, (H_2SO_4)

Moles of Sulfur atom = 1

Moles of Hydrogen atom = 2

Moles of Oxygen atom = 4

Mole ratio of the atoms: H : S : O = 2 : 1 : 4

  • In Butene, (C_4H_8)

Moles of Carbon atom = 4

Moles of Hydrogen atom = 8

Mole ratio of the atoms: C : H = 1 : 2

What was the advantageous adaptation mentioned that humans have evolved in order to survive
Marizza181 [45]
The  pattern  recognition  is  the  advantage  of  human  having evolved  in  order  to  survive. Each  stage of pattern  recognition  introduces   various  of   both  internal  and  external  noise  which  makes  accuracy  difficulties  and   it  is  exponentially  increasing  as  you  move  down  the  chain. As  pointed out  signal  detection  theory  can   never  be  perfect and must  be  traded  off  between missing pattern  and  .

Lubov Fominskaja [6]

Answer;

-Aerobic respiration;

Explanation;

-Aerobic respiration is the process in living things that evolved as oxygen levels increased in earth's atmosphere. Aerobic respiration is the process in which cellular energy is produced in the presence of oxygen. Cells breakdown nutrients, such as glucose, in the mitochondria to produce energy in the form of ATP which can be used by the cells.
