Answer:contact forces or transfer energy(not sure)
Explanation:
Answer:
<u>One Electron</u> is transferred.
Explanation:
The reaction is as follow,
<span> AgNO</span>₃<span> + Na </span>→ <span>NaNO</span>₃<span> + Ag
Reduction of Ag;
AgNO</span>₃ + 1 e⁻ → Ag
Oxidation State +1 0
Oxidation of Na;
Na → Na⁺ + 1 e⁻
Oxidation State 0 +1
Result:
Therefore, Sodium transfers one electron to silver to reduce it.
Answer:
Explanation:
Benzene is an example for six membered aromatic hydrocarbons
29. B) A population changes in response to a change in the environment.
<u>Evolution is the process by which new species of organisms develop from earlier forms. Most often, in response to a change in a species environment. It's the frequent change of the alleles in a population. </u>
30. A) Describes the relationship between an organism and its environment
<u>Darwin made this theory of evolution by natural selection as an explanation for adaptation. Darwin defined natural selection as the </u>
<u>"principle by which each slight variation, if useful, is preserved."</u>
There are two subshells that are s and p, which are present in the second energy level.
The energy level can be defined as the fixed distances from the nucleus of an atom where electrons may be found. Each energy level is divided into some Subshells. These subshells are known as s-subshell, p-subshell, d-subshell, and f-subshell. This subshell contains some orbitals, these orbitals are the place where there is the maximum probability of getting the electrons. In one orbital, a maximum of two electrons can be present.
Hence, there are two subshells in the second energy level.
