Explanation:
I'm not sure if this is what you are looking for but i will attempt to answer.
Isotopes are variations of the same atom. They have the same number of protons but have a different number of neutrons. As a result of this, the atomic number remains the same but the mass number changes.
A calculation you could perform in relation to isotopes would be calculating the relative atomic mass. The relative atomic mass is the weighted average of masses of isotopes.
Relative atomic mass (RAM)= the addition of
For example, the element Indium has a relative isotopic mass of 112.90406, 4.29% of the time. It has a relative isotopic mass of 114.903878, 95.71% of the time.
From this
RAM=
2Al+6HCl ->2AlCl3+3H2 .nAl=m/M=13,5/27=0,5(mol) =>nH2=0,5.3/2=0,75(mol)....VH2=n.22,4=0,75.22,4=16,8(lít)...

Explanation:
Hello,
Based on the information, one could use the following formula to compute the magnitude of acceleration in this case:
Now, final velocity is after the 4.0 s have passed, it means 4.0 m/s. On the other hand, initial velocity is taken into account at t=0.0s. Thus, the acceleration turns out into:
The magnitude of acceleration is then 4m/s^2 and the sign suggests the direction; in such a way, since it has a negative value, it means that the acceleration shifts leftwards, which accounts for a breaking.
Best regards.
either c or d but more likely d because food is mainly broken down in your stomach
