Answer:
No
Explanation:
No, Ana's prediction of sorting out : mixture 1 'marble salt' with by her fingers, ie handpicking is not right.
Marble & salt particles mixture can't be sorted by handpicking. They can be seperated by the method of sieving rather, as marble particles being bigger stay in the sieve & salt particles being smaller (finer) pass through it.
he mass defect of the helium nucleus ⁴He₂ is 0.030377 u
Further explanation
Mass defect means the difference between the mass of particles forming an atom with an atomic mass.
Δm = mass defect ( u )
mp = mass of proton ( u )
me = mass of electron ( u )
mn = mass of neutron ( u )
M = atomic mass ( u )
A = mass number
Z = atomic number
