6 0

Answer:

B.) The number of atoms is the same in the reactants and in the products, and the total mass is the same in the reactants and in the products.

Explanation:

law of conservation of matter/mass states that no atoms can be created or destroyed

hope this helps :)

In modern atomic theory, bohr's orbits are replaced by atomic orbitals. what is an atomic orbital?
Darya [45]

Bohr's theory states that the motion of the electron (particle) around the nucleus is very much similar to motion of the planets around the sun in the solar system. Both in the mathematical and physical sense.

The Bohr's Atomic theory only explains the motion of the electrons in discrete atomic orbitals that are predicted by the Bohr's equation.

It strictly implies that the electron only exists in these discreet orbitals and fails to explain anything about the nature of the electron in between the discrete orbitals.

The modern atomic theory does not share this limitation as it does not impose the electron to only occupy the discrete orbitals and neither does it impose particle nature upon the electron.

In the modern theory does not focus on describing the motion of the electron around the orbital but rather the probability of finding an electron around the nucleus. The modern atomic orbitals or electron clouds are the regions in which the probability of finding the electron is the highest when the wave function collapses.  The Schrödinger's wave equation explains the evolution of the wave function in time. Hence enabling us to predict the future possible locations of the electron but never the exact location as that is impossible due to the Heisenberg's Uncertainty principle.

What determines how the atoms are organized on the periodic table of elements?
tresset_1 [31]
The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods.

Which statements describe abiotic factors in an environment? Check all that apply.
olga nikolaevna [1]

Soil retains water and nutrients.

Several rocks rest in a stream.

Clouds create shade that changes temperatures

Abiotic factors are non-living components in the environment, or rather components in the environment that are not derived from life.

Explanation:

Abiotic factors interact with biotic factors to create ecoystems. An example of biotic factors interacting with abiotic factors include plants utilizing sunlight for photosynthesis and a wild beast drinking water form a watering hole in the middle of the savanna.
