Which hypothesis regarding the origin of life on Earth suggests that oxidation-reduction (redox) reactions may be responsible fo
telo118 [61]

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.

Which polyatomic ion forms A neutral compound when combined with group a1 monotonic ion in a 1:1
kolezko [41]

Answer:

"Nitrate" is a polyatomic ion forms A neutral compound when combined with group a1 monotonic ion in a 1:1

Explanation:

Nitrate is a polyatomic ion with the molecular formula NO⁻ ₃. Organic complexes that comprise the nitrate ester as a functional group are also named nitrates. Nitrates are shared apparatuses of fertilizers and explosives. Almost all nitrate salts are soluble in water. Usually nitrates that enter the body by eating or drinking leave the body without harm. These nitrites in the blood cause changes in hemoglobin, or the molecules that help move oxygen in the body. Nitrates can make it so that less oxygen is available for the body to function properly.

When a chemical reaction is at equilibrium, which of the following statements is always TRUE?
AysviL [449]

<u>Answer:</u> The correct answer is Option D.

<u>Explanation:</u>

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric coefficients. It is represented by K_{eq}

For a general chemical reaction:

aA+bB\rightarrow cC+dD

The K_{eq} is written as:

K_{eq}=\frac{[C]^c[D]^d}{[A]^a[B]^b}

There are 3 conditions:

  • When K_{eq}>1; the reaction is product favored.
  • When K_{eq}; the reaction is reactant favored.
  • When K_{eq}=1; the reaction is in equilibrium.

At equilibrium, the  ratio of concentration of reactants to the concentration of products is equal to 1.

At equilibrium, the rate of forward reaction is equal to rate of backward reaction.

Hence, the correct answer is Option D.
