The hypothesis that suggests that redox reaction is responsible for the formation of complex organic molecules is :

  • Reducing Atmosphere Hypothesis

<h3>Reducing atmosphere</h3>

Reducing atmosphere hypothesis states that a reducing atmosphere is a condition whereby the atmosphere has an abundance of negative charges which leads to reducing reaction by the additon of electrons to compounds.

The addition of electrons to the compounds leads to the formation of complex organic molecules. some examples of reducing gases are :

  • Hydrogen and
  • Carbon monoxide

Hence we can conclude that The hypothesis that suggests that redox reaction is responsible for the formation of complex organic molecules is : Reducing Atmosphere Hypothesis.

What is the mass number of sodium?
Nataliya [291]

Answer: Since all sodium atoms have 11 protons, this one has 11 protons. This tells us that it also has 11 electrons. Since the mass number is 23, we know that the sum of protons and neutrons in the nucleus must equal 23.

So the answer is : Mass number = 23

What is the pH of a solution that has a concentration of 1 X 10-3 hydrogen ions?
kykrilka [37]

Given :

Concentration of hydrogen ions, H^+ = 10^{-3} \ ions.

To Find :

The pH of a solution.

Solution :

We know, pH of a solution is given by :

pH = - log [ H^+]\\\\pH = -log ( 10^{-3})\\\\pH = 3

Therefore, the pH of the solution is 3 .

How many moles of ammonia are there in a 346 g sample of pure nh3?
Citrus2011 [14]
Molar mass NH3 = 17.031 g/mol

1 mole NH3 -------------- 17.031 g
?? moles NH3 ---------- 346 g

346 x 1 / 17.031

=> 20.31 moles of NH3

skad [1K]
<span>It generally does not mean that there is double the oxygen, but in this case there is double, because the subscript number tells how many atoms of that element are in a particle. In this case, there are two of the oxygen, hence the DI-oxide verbiage, and one of the carbon. When there is only one, it's MONOxide, to indicate only one atom.</span>
