Answer:

Primordial soup

Explanation:

The primordial soup is a theoretical mixture of organic compounds (water vapor, carbon dioxide, nitrogen, methane and ammonia) that may have given rise to life on Earth. When one wants to explain how living organisms appeared on Earth, the theory of primordial soup is often used, which seems to be the most plausible scientific explanation.

Conditions on Earth in its early days were very different from current conditions. The atmosphere had no oxygen, being rich in hydrogen, ammonia, methane and water. According to the primordial soup theory, these substances were prepared to produce amino acids, which would have been able to combine to create organic material that, eventually, could have given rise to life. In order for this to happen, it was necessary to have a catalyst; the amino acids did not appear spontaneously.

The only molecules that can be considered "organic" are methane and carbon dioxide, but these are abiotic and not considered fundamental in the biochemical molecular structure of the first organism.

The likely designation of the list of molecules is "primordial soup," but the proposition that these somehow collected, merged and formed anything associated with the first organism is naturalist mythology, as there are no naturalist processes capable of selectively formulating the required biochemical assemblies needed to construct a functioning organism.

Abiogenesis, the naturalist myth of origin of life is based on chemical evolution, as the Darwinian myth of "warm little ponds," Oparin-Haldane primordial soup, and Miller-Urey test tube goo. No naturalist processes can assemble all the required biochemically required compounds required for the the origin of life.

List the following bond types in order of increasing strength: non-polar covalent bonds, ionic bonds, hydrogen bonds, polar cova
ss7ja [257]

Answer: Option (B) is the correct answer.

Explanation:

  • An ionic bond is formed by the sharing of electrons between two chemically combining atoms.

In an ionic bond, there occurs attraction between oppositely charged ions due to which there occurs strong forces of attraction between them. Therefore, ionic bonds are the strongest bonds.

  • A polar covalent bond is formed due to unequal sharing of electrons between the combining atoms.

For example, H_{2}O is a polar covalent compound. Partial opposite charges tend to develop on the atoms of a polar covalent compound.

  • A non-polar covalent bond is formed due to equal sharing of electrons between the combining atoms.

For example, Cl_{2} is a non-polar covalent molecule. No partial charges will be there on the atoms of a non-polar covalent molecule.

  • A hydrogen bond is defined as the bond formed between a hydrogen atom and an electronegative atom.

For example, in HCl compound there occurs hydrogen bonding.

In this type of bond, dipole-dipole attractive interactions tend to take place. And, strength of hydrogen bonds is very weak.

Thus, we can conclude that given bond types are arranged in order of increasing strength as follows.

      Hydrogen bonds < non-polar covalent bonds < polar covalent bonds < ionic bonds

To answer this question, you will need to write the balanced equation and set up a BCA table. Using appropriate rounding rules,
Elenna [48]

Water decomposes when electrolyzed to produce hydrogen and oxygen gas. If 2.5 grams of water were decomposed 1.04 grams of oxygen will be formed.

BCA table:

2H_{2}O ⇒ H_{2} + O_{2}

B  0.13        0 + 0

C  -0.13      0.065 + 0.065

A  0             0.065

Explanation:

Balanced equation for water decomposition into hydrogen and oxygen gases

   2H_{2}O ⇒ H_{2} + O_{2}

B  0.13        0 + 0

C  -0.13      0.065 + 0.065

A  0             0.065

Number of moles of water = \frac{mass}{atomic mass of 1 mole}

mass = 2.5 grams

atomic mass= 18 grams

number of moles can be known by putting the values in the formula,

n = \frac{2.5}{18}

  = 0.13 moles

2 moles of water gives one mole of oxygen on decomposition

so, 0.13 moles of water will give x moles of oxygen on decompsition

\frac{1}{2} = \frac{x}{0.13}

x = 0.065 moles of oxygen will be formed.

moles to gram will be calculated as

mass =number of moles x atomic mass

        = 0.065 x 16

         = 1.04 grams of oxygen.
