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.

What is the empirical formula of C3H6N2
Evgen [1.6K]

Answer:

The empirical formula of the compound C₃H₆N₂ is C₃H₆N₂

Explanation:

The empirical formula of a compound is the formula of the compound given in the (smallest) whole number ratio of the elements of the compound

The empirical formula of S₂O₂ is SO

The empirical formula of C₃H₆O₃ is CH₂O

The given compound's molecular formula is C₃H₆N₂

The smallest whole number ratio of of the elements of the compound is 3:6:2, therefore, the empirical formula of the compound C₃H₆N₂ is C₃H₆N₂.

Density is the ratio of a sample's mass to its volume. A bar of lead has a mass of 115.2 g. When it is submerged in 25.0 mL of w
Margarita [4]

Answer:

$10.97 \ g/cm^3$

Explanation:

Given :

Mass of a bar of lead = 115.2 g

Initial water level $\text{in the graduated cylinder}$ = 25 mL

Final water level $\text{in the graduated cylinder}$ = 35.5 mL

Difference in the water level = 35.5 - 25

                                               = 10.5 mL

                                               = 10.5 \ cm^3

We know that when a body is submerged in water, it displaces its own volume of water.

Therefore, the volume of the lead bar = volume of the water displaced = 10.5 mL  = 10.5 \ cm^3

We know that mathematically, density is the ratio of mass of body to its volume.

Density of the lead bar is given by :

$\rho =\frac{\text{mass}}{\text{volume}}$

$\rho =\frac{\text{115.2 g}}{\text{10.5 cm}^3}$

  = $10.97 \ g/cm^3$

In a classroom which comparison would a teacher most likely use for describing a mole
irina [24]
Mole - one of the most important concepts in chemistry - is a kind of link to go from the microworld of atoms and molecules in a normal macrocosm grams and kilograms.
In chemistry often have to consider large numbers of atoms and molecules. For fast and efficient calculation made using the weighing method. But it is necessary to know the weight of individual atoms and molecules. In order to identify the molecular weight must be added the weight of all atoms in the compound.
