Answer:
It's better to explain it.
Explanation:
Neutrons do not affect the electron configuration, but the sum of atomic number and the number of neutrons, or neutron number, is the mass of the nucleus. You know that neutrons are found in the nucleus of an atom. Under normal conditions, protons and neutrons stick together in the nucleus. During radioactive decay, they may be knocked out of there. Neutron numbers are able to change the mass of atoms, because they weigh about as much as a proton and electron together. if your asking What is the role of a neutron in an atom? then, Neutrons are very important in providing stability for an atom. Some atoms don't "need" neutrons - The hydrogen atom does not have any neutrons. However, as the atomic number ( # of protons ) increases, the number of neutrons increases as well.
Protons don't like each other. Naturally, 'positive charges repel', so it wouldn't be possible to have more than one proton in the nucleus. Here's where the neutron comes in.
Hope this helps. :)
Answer:
A reaction is spontaneous if ΔG is negative.
Explanation:
- The change in free energy (ΔG) is the difference between the heat released during a process and the heat released for the same process occurring in a reversible manner.
- The sign of ΔG gives an indication for the spontaneity of the reaction:
If ΔG is negative, the reaction is spontaneous.
If ΔG = zero, the reaction is at equilibrium.
If ΔG is positive, the reaction is non-spontaneous.
Answer:
By Filtration using Filter Paper
Explanation:
Aluminium Powder is made from Aluminium with the help of mechanical means. This powder is mainly used in paints, cosmetics, fingerprint powders, thermite, rocket fuels e.t.c.
Also, Aluminium Powder is insoluble in water and organic solvents. Therefore, when mixed in Ethanol it will form a suspension. The Aluminium Powder can therefore be easily separated by simple Filtration using Filter paper.
Herbivores, which eat autotrophs, are the second trophic level. Carnivores, organisms that consume animals, and omnivores, organisms that consume both plants and animals, are the third trophic level. Autotrophs are called producers, because they produce their own food.
