<h3>Further explanation </h3>The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.
Usually radioactive elements have an unstable atomic nucleus.
The main particles are emitted by radioactive elements so that they generally decay are alpha (α), beta (β) and gamma (γ) particles
General formulas used in decay:
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
No=192 μCi
Nt=3 μCi
t1/2=2.67 days
Answer:- 27.9 g of hydrogen.
Solution:- The given balanced equation is:
The problem asks to calculate the grams of hydrogen required to react completely with 6.50 moles of CO.
We will start with 6.50 moles of CO and multiply it by the mol ratio to get the moles of hydrogen. Looking at the balanced equation, there is 8:17 mol ratio between CO and .
In next step, the moles of hydrogen are converted to grams on multiplying the moles by molar mass.
Molar mass of is 2.02 g per mol. The set up is made using dimensional analysis and shown below:
= 27.9 g
So, 27.9 grams of [tex]H_2] will react completely.
