<span>Two scientists wrote a paper detailing their research and conclusions and submitted it to a scientific journal. Several months later, they received the paper back from the publisher with many comments attached from several fellow scientists. It is either that they revise their study or replicate the study. Most scientists would revisit their work and the findings they had from their research. Most probable if they were successful and the comments of the publisher and the co-scientists were positive they could replicate the study to validate its accountability.<span>

Answer: If the oxidation number of copper changes from 0 to +2 then yes this is a redox reaction as copper lost 2 electrons and was oxidized.
Explanation:
When an element or atoms loses an electron then it acquires a positive charge.
This charge on an atom represents its oxidation state.
For example,
Here, oxidation number of copper changes from 0 to +2.
A redox reaction in which electrons are removed from an atom or a reaction where an increase in oxidation number of an atom takes place is called oxidation-half reaction. The atom itself gets oxidized.
This means that here copper lost 2 electrons and was oxidized.
Thus, we can conclude that if the oxidation number of copper changes from 0 to +2 then yes this is a redox reaction as copper lost 2 electrons and was oxidized.
I think the answer is sunlight
Answer:
There are other details missing in the question. i.e Assume that x is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis E = p/2πε0y3 can be used, where p is the dipole moment, and y is the distance between ions. A) What is magnitude______N B) Direction? +x-direction or -x-direction C) Is this force attractive or repulsive?
A) Magnitude of electric force = 6.576 x 10 raised to power -13 N
B) Since the force direction is always dependent on the electric field and electric field = F/q, since the chlorine has a negative charge as such the direction of the electric force will be in the X - direction
C) Since the charges are of different nature, as such the force between them will be ATTRACTIVE.
Explanation:
The detailed steps is shown in the attachment
The answer is B. The strength of the magnetic field decreases.
