When P1/P2 = C1/C2
and C is the molarity which = moles/volume
so, P1/P2 = [(mass1/mw)/volume] / [(mass2/mw)/volume]
P1/P2 = (mass1/mw)/1.5L / (mass2/mw)/1.5L
so, Mw and 1.5 L will cancel out:
∴P1/P2 = mass1 / mass2
∴ mass 2 = mass1*(P2 / P1)
= 0.278g * (78 bar / 62 bar)
= 0.35 g
∴ the quantity of argon that will dissolve at 78 bar = 0.35 g
1. Fossils, rocks and mountain range
2. The location of ancient climatic zones.
3. The continents have moves from the continental drift several lines of evidence
Answer:
The half-life varies depending on the isotope.
Half-lives range from fractions of a second to billions of years.
The half-life of a particular isotope is constant.
U^235Number of protons = 92 pNumber of electrons = 92 eNumber of neutrons = 235 – 92 = 143n
U^238Number of protons = 92pNumber of electrons = 92eNumber of neutrons = 238 – 92 = 146n
Electron configuration of U atom U = 92 U = [Rn] 5f^6 6d^0 7s^0 U = [Rn] 5f^36d^17s^2, 7s is completely filled and others are less than half filled.
(_92^238)U Decays to (_90^234)ThIt loses 2 protons, 2 electrons and loses 2 neutrons Th = [Rn] 6d^2 7s^2 There is no electron in 5f subshell and 6d contains 2e^-, 7s completely filled
Answer:
The correct option is: D. A suspension
Explanation:
A suspension is a type of heterogeneous mixture in which solid particles are suspended through out the bulk of the solvent through mechanical agitation. The solid phase is also known as the internal phase and the solvent is known as external phase. In a suspension, the solid particles are generally larger than one micrometer and thus are unable to dissolve in the medium. The solid particles of a suspension are large enough to get precipitated.
<u>Therefore, in the given situation, the chicken broth is </u><u>a suspension</u><u> </u>as the contents or solid particles of the container needs to be suspended in the solvent by shaking to prevent sedimentation.
