Fast, slow, why do some reactions occur faster than others?

Chemistry
1 answer:
Liula [17]3 years ago
3 0

Answer:

When the concentration of a reactant increases, there will be more chemical present. Due to more reactant particles moving together, more collisions are allowed to happen and with that, the rate of the reaction is increased. So, the higher the concentration of reactants, the faster the reaction rate will be.

Hope this helped you! :)

When a vacancy exists in an inner electron shell of an atom (as a result of photoelectric effect, Compton scattering, or bombard
Helen [10]

Answer:

The answer is "Auger".

Explanation:

The Auger effect is an effect size when the vacancy of even an atom throughout the inner shell was complemented by the release of even an electron from the same atom. Whenever a central electron is lost, a higher energy level electron can drop into the void and release energy, which can be the result.

Electrons surround the , of an atom in various energy levels called
nasty-shy [4]

surrounds the nucleus of an atom in various energy levels called orbitals.

Explanation:

Electrons surrounds the nucleus of an atom in various energy levels called orbitals.

According to the Bohr's model of an atom, the extra nuclear space is made up of electrons in specific spherical orbits called shells or energy levels.

  • The region of a maximum probability of where an electron is located is sometimes referred to as an electron cloud or orbital.
  • Electrons move round the nucleus in certain permissible orbits.
  • An electron in an energy level posses a definite amount of energy associated with it at that level.
  • Electrons moves through the energy levels by gaining or losing energy.

How many moles of hcl are required to make 500 ml of a 3.0 mol/l solution of hcl?
LiRa [457]

Answer:

1.5 moles

Explanation:

To find the number of moles of HCl in 500 mL of a 3 M solution of HCl, we consider moles in 1 liter/ 1000 mL.

3 moles HCl is contained in 1000 mL

x moles is HCl is contained in 500 mL

=  \frac{3 \:  \times  \: 500}{1000}  \: moles \\  = 1.5 \: moles

Hence the number of moles of HCl in 500 mL is 1.5 moles.
