Answer:
covalent bond is the answer
Alpha particles, also called alpha ray or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a <u>helium-4 nucleus. </u>They are generally produced in the process of alpha decay, but may also be produced in other ways.
Composition: 2 protons, 2 neutrons
Mass: 6.644657230(82)×10−27 kg; 4.0015061...
Electric charge: +2 e
Symbol: α, α2+, He2+
The concentration of a cell is generally 0.15 M (0.9 % NaCl)
As given the solution has concentration = 200mm = 0.02 M
This concentration of solution is less than the concentration of cell
Hence solution is hypotonic (less concentration) and cell will be hypertonic
Answer:
The ΔS° for this reaction is -626.22 J/K.
Explanation:
The equation used to calculate ΔS° is of a reaction is:
![\Delta S^o_{rxn}=\sum [n\times \Delta S^o_f(product)]-\sum [n\times \Delta S^o_f(reactant)]](https://tex.z-dn.net/?f=%5CDelta%20S%5Eo_%7Brxn%7D%3D%5Csum%20%5Bn%5Ctimes%20%5CDelta%20S%5Eo_f%28product%29%5D-%5Csum%20%5Bn%5Ctimes%20%5CDelta%20S%5Eo_f%28reactant%29%5D)
The equation for the enthalpy change of the above reaction is:
We are given:
Putting values in above equation, we get:
The ΔS° for this reaction is -626.22 J/K.
