Answer:
Ernest Rutherford postulated the nuclear structure of the atom, discovered alpha and beta rays, and proposed the laws of radioactive decay. He received the Nobel Prize in Chemistry in 1908.
Erwin Schrödinger proposed the quantum mechanical model of the atom, which treats electrons as matter waves. ... The Heisenberg uncertainty principle states that we can't know both the energy and position of an electron.
hope it helps
The neutralization of the base with an acid will result to the formation of salt and water. In this case, a mole of strong acid will have one halide that will react with the Na atom. Since there are two Na atoms in each of the molecule of Na2HPO4, this will need 2 halide atoms.
Answer:
7.5 × 10¹⁵ Hz
Explanation:
Given data
- Wavelength of the radio waves (λ): 40 nm = 40 × 10⁻⁹ m = 4.0 × 10⁻⁸ m
- Frequency of the radio waves (ν): ?
- Speed of light (c): 3.00 × 10⁸ m/s
We can determine the frequency of the radio waves using the following expression.
c = λ × ν
ν = c/λ
ν = (3.00 × 10⁸ m/s)/4.0 × 10⁻⁸ m
ν = 7.5 × 10¹⁵ s⁻¹ = 7.5 × 10¹⁵ Hz
Answer:
The scientist have developed to classify organisms because the living things with similarities can put into groups, which can further make easy to understand the relationship between them.
Explanation:
The scientist have classified organisms in different groups which can make their study easier. In this manner the organisms with same character will be in same group and their relationship and behavior with themselves as well as with others can be studied easily. It will make things less confusing. In this way the inheritance and genetic behavior can also be studied easily. This classification are based on various other categories like structure, function and also relationship with others.
