Answer:
The answer to your question is below:
Explanation:
Density: is the ratio between the mass of an object and its volume.
density = mass/ volume. Its units are g/ml, g/cm³ or kg/m³.
What does it tell you about the substance?
Density tells the degree of compactness of a substance. It could tell if the substance is solid or it is porous.
Diffusion is a spontaneous movement of particles from an area of high concentration to an area of low concentration. ... Osmosis is the spontaneous net movement of water across a semipermeable membrane from a region of low solute concentration to a more concentrated solution, up a concentration gradient.
Answer:
80g=0.08kg
20cm=0.02m
density=m/v
= 0.08/0.02
=4kg/m^3
it is less than density of water so it floats
Answer:
Following are the chemical equation to the given question:
Explanation:
The Electrode is a silver film that is covered with such a thin coating of silver chloride, either by dipping its wire directly into silver-molten chloride, plating the wire using hydrogen peroxide, or oxidation silver in a chloride. In the given silver electrode, this anode acts as a cathode and thus reduces.
Half of the response reduction:
Half-effect oxidation:
