Protons= Atomic Number (44).
Neutrons= Atomic Mass (106) - Atomic Number (44) = 62.
Therefore RUTHENIUM-106 has 44 protons and 62 neutrons.

Answer:
Explanation:
Answer:
A. to determine the efficiency of the reaction
Explanation:
Percentage is the ratio of the actual yield to theoretical yield as a percentage. It is calculated by dividing the actual yield by theoretical yield then multiplying by 100%.
Calculation of percentage yield is important as it helps in the determination of efficiency of a reaction. For example in most industries for the purpose of making the most product with the least waste.
Additionally, calculating the percentage yield helps in determining other products that may be formed during the reactions.

Given
Nt = 2.5 g C-14
No = 40 g
half-life = 5730 years
Required
time of decay
Solution
General formulas used in decay:
![\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{t/t\frac{1}{2} }}}](https://tex.z-dn.net/?f=%5Clarge%7B%5Cboxed%7B%5Cbold%7BN_t%3DN_0%28%5Cdfrac%7B1%7D%7B2%7D%29%5E%7Bt%2Ft%5Cfrac%7B1%7D%7B2%7D%20%7D%7D%7D)
t = duration of decay
t 1/2 = half-life
N₀ = the number of initial radioactive atoms
Nt = the number of radioactive atoms left after decaying during T time
Input the value :
![\tt 2.5=40.\dfrac{1}{2}^{t/5730}\\\\\dfrac{2.5}{40}=\dfrac{1}{2}^{t/5730}\\\\(\dfrac{1}{2})^4=\dfrac{1}{2}^{t/5730}\\\\4=t/5730\rightarrow t=22920~years](https://tex.z-dn.net/?f=%5Ctt%202.5%3D40.%5Cdfrac%7B1%7D%7B2%7D%5E%7Bt%2F5730%7D%5C%5C%5C%5C%5Cdfrac%7B2.5%7D%7B40%7D%3D%5Cdfrac%7B1%7D%7B2%7D%5E%7Bt%2F5730%7D%5C%5C%5C%5C%28%5Cdfrac%7B1%7D%7B2%7D%29%5E4%3D%5Cdfrac%7B1%7D%7B2%7D%5E%7Bt%2F5730%7D%5C%5C%5C%5C4%3Dt%2F5730%5Crightarrow%20t%3D22920~years)
