Why ions move and in which direction they move in the presence of an electric field created between two electrodes having opposi

te charges
Chemistry
1 answer:
Allushta [10]2 years ago
8 0

Answer and Explanation:

In an electric field generated between two electrodes there is a separation of charges: a negatively charged electrode called <u>cathode</u> and a positively charged electrode called <u>anode</u>. Ions are charged particles, so they can be positive or negative charges. Opposite charges attract each other. So, the cathode - negatively charged - attracts positively charged particles. On the other hand, the anode - positively charged - attracts negatively charged particles.

Therefore, positive ions move towards the cathode and negative ions move towards the anode.

What is the difference between a state and a microstate of a system?
Brut [27]

Answer:

a) A microstate is a snapshot of positions and speeds at a particular instant.

b) A thermodynamic state is a single possible arrangement of the positions and kinetic energies of the molecules.

c) A thermodynamic state is a set of conditions, usually temperature and pressure, that defines the properties of a bulk material.

d) A microstate is a single possibility for all the positions and kinetic energies of all the molecules in a sample.

e) A thermodynamic state is a set of conditions, usually temperature, volume and number of moles, that defines the properties of a bulk material.

Explanation:

A state of a system in thermodynamics give the properties that a material is been made up, these properties could be pressure, temperature, volumes and others , they are been called thermodynamic property

Microstates helps us to know how molecules is been arranged in single instant. Kinetics energy as well as position of molecules in a particular substance can be known in single instant.

A sample of metal has a mass of 21.35 g, and a volume of 6.28 mL. What is the density of this metal?
Scilla [17]

Answer:

3.40g/mL

Explanation:

Density is a measure of mass over volume, so to get the density all we have to do is divide the mass by the volume.

21.35g ÷ 6.28 mL = 3.40g/mL

A gas generation tube contains both the reactants involved in a chemical reaction and the gases that are produced.
Lady bird [3.3K]

The reaction will come to an end if all the reactants are used up. The reaction's limiting reactant is reactant B.

Limiting Reactant: The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be obtained.

This reactant is the one that restricts the production of products throughout the reaction. The reaction will come to an end if all of the reactants are used up.

surplus reactant

This is the limiting reactant that is present in excess and reacts with it all. Oxygen in the surroundings, as an illustration.

When all of the reactant B has been utilized, the reaction ends.
