Answer:
In blood: Disperse phase : blood cell ; Dispersed medium : liquid plasme
In fruit jelly: Disperse phase : Fruit juice ; Dispersed medium : Pectin
Explanation:
Dispersion phase is defined as phase in which is present or scattered into another phase as colloidal particle is called dispersion phase.
The medium in which dispersed phase is present is called dispersed medium.
So, in a blood, tiny cells are the colloidal particles are dispersed phase which are present in the liquid medium called plasma.
The dispersed phase in fruit jelly is fruit juice is present as liquid in a pectin which is dispersed medium. Whereas pectin is in solid state
Answer:
2900 moles gas
Explanation:
PV =nRT => n = PV/RT
at STP ...
P = 1 Atm
V = 64.6KLiters = 6.46 x 10⁴ Liters
n = unknown
R = 0.08206 L·Atm/mol·K
T = 0⁰C = 273K
n = (1 Atm)(6.46 x 10⁴L)/(0.08206 L·Atm/mol·K)(273K) = 2897 moles ≈ 2900 moles
Answer:
210 82Pb-----> 206 80Hg + 4 2 He
55 24 Cr----->55 25 Mn + 0 -1 e
76 35 Br + 0 -1 e-----> 76 34 Se
Explanation:
Alpha decay occurs with atoms having high atomic number number. As the atomic number increases, the repulsions between the protons make the nucleus unstable. A point is reached where the attractive forces in the nucleus are unable to hold the nucleons together anymore. Part of the nucleus now breaks off as an alpha particle or a helium nucleus.
Beta decay involves the transformation of a neutron to a proton, electron and neutrino. It decreases the neutron-proton ratio.
The capture of an orbital electron converts a proton into a neutron with the emission of a neutrino. The atomic number of the product nucleus decreases. Orbital electron capture increases the neutron-proton ratio.
I really don’t know Actually I have to learn:(
The type of charge an electron carries is B negative
