The partition coefficient K in a gas chromatographic experiment can be described by: Cm Cs K = where "Cs" and "Cm" refer to the

concentration of solute in stationary and mobile phases respectively. A large value of K implies ___.
Physics

Amiraneli [1.4K]3 years ago
4 0

Explanation:

K in chromatography is defined as a partition coefficient. It is an equilibrium constant that determines the measure to which the solutes partition between  two phases.

K = Cm/Cs

where Cm is solute concentration in mobile phase

          Cs is solute concentration in stationary phase

When K is more, then it implies that the solute concentration in the mobile phase is more in chromatography test.

E=mc^2 n its given 1kg = 9x10^16J

so need to figure out the total mass loss n u can find the energy released

mass loss when 4x H atom combines to form 1x He atom in a fusion reaction is given as 4.59x10^-29kg

1 mole of He has 6.02x10^23 He atoms

so 2.7 moles of He has 2.7x6.02x10^23 He atoms

the total mass loss for 2.7 moles of He created in a fusion reaction

= 2.7x6.02x10^23 x 4.59x10^-29kg

= 7.46x10^-5kg

radiation energy released from this fusion reaction

= 7.46x10^-5 x 9x10^16J

= 6.7x10^12J

its 60 BILLION times more than burning carbon!!

Sidana [21]

Complete Question

The spaceship Intergalactica lands on the surface of the uninhabited Pink Planet, which orbits a rather average star in the distant Garbanzo Galaxy. A scouting party sets out to explore. The party's leader–a physicist, naturally–immediately makes a determination of the acceleration due to gravity on the Pink Planet's surface by means of a simple pendulum of length 1.08m. She sets the pendulum swinging, and her collaborators carefully count 101 complete cycles of oscillation during 2.00×102 s. What is the result? acceleration due to gravity:acceleration due to gravity: m/s2

Answer:

The acceleration due to gravity is  g = 167.2 \ m/s^2  

Explanation:

From the question we are told that

     The length of the simple pendulum is L = 1.081.08 \ m

      The number of cycles is  N =  101

       The time take is  t =  2.00 *10^{2 \ }s

Generally the period of this oscillation is mathematically evaluated as

         T = \frac{N}{t }

substituting values

         T = \frac{101}{2.0*10^2 }

        T = 0.505 \  s

The period of this oscillation is mathematically represented  as

               T = 2 \pi \sqrt{\frac{l}{g} }

making g the subject of the formula we have

              g = \frac{L}{[\frac{T}{2 \pi } ]^2 }

              g = \frac{4 \pi ^2 L }{T^2 }

Substituting values

               g = \frac{4 * 3.142 ^2  * 1.08 }{505.505^2 }

               g = \frac{4 * 3.142 ^2  * 1.08 }{0.505^2 }  

              g = 167.2 \ m/s^2

Why should it take significantly more energy to move a beam of alpha particles than a beam of beta minus (β–) particles?
a_sh-v [17]
An 'alpha particle' is the same thing as the nucleus of a helium atom ... 
a little bundle made of 2 protons and 2 neutrons.

A 'beta' particle is an electron.

The mass of an alpha particle is more than 7,000 times the mass of 
an electron, so it certainly takes more energy to get it moving.
