Answer:
3 years
Explanation:
Given data:
Initial amount of sample = 160 Kg
Amount left after 12 years = 10 Kg
Half life = ?
Solution:
at time zero = 160 Kg
1st half life = 160/2 = 80 kg
2nd half life = 80/2 = 40 kg
3rd half life = 40 / 2 = 20 kg
4th half life = 20 / 2 = 10 kg
Half life:
HL = elapsed time / half life
12 years / 4 = 3 years
The compound responsible for the characteristic smell of garlic is allicin, that is having molecular formula C₆H₁₀OS₂.
Molar mass of C₆H₁₀OS₂=162.26 g mol⁻¹.
number of moles of C₆H₁₀OS₂=1 mol
So mass of C₆H₁₀OS₂ can be calculated as:
Given mass of the C₆H₁₀OS₂= 162 g
The orbital shape, i.e. the radial probability distribution, of the 2s sublevel shows it to be more stable than that of the 2p sublevel because it closer to The nucleus.
The nucleus of an atom consists of neutrons and protons, which in flip are the manifestation of more primary debris, known as quarks, which are held in affiliation through the nuclear sturdy pressure in positive solid combos of hadrons, referred to as baryons.
The nucleus of the atom, also called the atomic nucleus, is the small, dense, spherical center of an atom. The nucleus incorporates subatomic debris: the protons and the neutrons. Protons are definitely charged particles with a mass of about 1 amu (atomic mass unit).
It is composed of protons, which have a fantastic charge, and neutrons, which haven't any price. Protons, neutrons, and the electrons surrounding them are lengthy-lived particles found in all ordinary, clearly going on atoms.
