Answer:
Yes
Explanation:
As the earth orbits around the earth, the moon orbits around us, meaning it shows its entire body as it orbits
Their positive charge is located in a small region that is called the nucleus.
Explanation:
Ernest Rutherford in his gold foil experiment was able to demonstrate that the nucleus is made up of positive charges which occupies a small and tiny nucleus.
Rutherford bombarded a thin gold foil with alpha particles from a radioactive source.
- He observed that all the particles passed through but a small portion was deflected back.
- This led to his proposition of the nuclear model the atom.

Answer:
The balanced half-reaction for the reduction of dichromate ion to chromium ion in acidic aqueous solution:
Explanation:
The reaction :
Balancing of reaction in an acidic medium:
Step 1: Balance the atoms in the reaction:
Step 2: Balance oxygen atom by adding water on the side where no oxygen or less oxygen atom is present;
Step 3: Balance the hydrogen atom by adding hydrogen ions on the side where water is absent:
Step 4: Now balance charge by adding electrons on the side where more positive charge is present
The balanced half-reaction for the reduction of dichromate ion to chromium ion in acidic aqueous solution:
No, ammonium chloride in water is not a physical reaction. It is a chemical reaction. Hope this helps!
Answer:
It is called a reduction-oxidation, oxide-reduction reaction, or simply as a redox reaction, any chemical reaction in which one or more electrons are transferred between the reactants
Redox battery is an example of both a Flow Battery and a two electrolyte system.In this case, it depends on two different active aqueous electrolytes of vanadium dissolved in sulfuric acid separated by a membrane at which ionic interchange takes place.
Thats my opinión though.
