Why do isotope decay

Chemistry
1 answer:
BaLLatris [955]2 years ago
7 0

Instability

Explanation:

Isotopes decays because they are unstable. Stable isotopes do not decay.

  • For every atomic nucleus, there is a specific neutron/proton ratio.
  • This ratio ensure that a nuclide is stable.
  • For example, fluorine F, is 10/9 stable.
  • Any nucleus with a neutron/proton combination different from its stability ratio either too many neutrons or too many protons will become unstable.
  • Such nuclide will split into one or more other nuclei with the emission of small particles of matter and considerable amount of energy.

if i add 25 ml of water to 135 ml of a 0.25 M NaOH solution what will the molarity of the diluted solution be​
DENIUS [597]

Answer:

0.21 M. (2 sig. fig.)

Explanation:

The molarity of a solution is the number of moles of the solute in each liter of the solution. The unit for molarity is M. One M equals to one mole per liter.

How many moles of NaOH in the original solution?

n = c \cdot V,

where

  • n is the number of moles of the solute in the solution.
  • c is the concentration of the solution. c = 0.25 \;\text{M} = 0.25\;\text{mol}\cdot\textbf{L}^{-1} for the initial solution.
  • V is the volume of the solution. For the initial solution, V = 135\;\textbf{mL} = 0.135\;\textbf{L} for the initial solution.

n = c\cdot V = 0.25\;\text{mol}\cdot\textbf{L}^{-1} \times 0.135\;\textbf{L} = 0.03375\;\text{mol}.

What's the concentration of the diluted solution?

\displaystyle c = \frac{n}{V}.

  • n is the number of solute in the solution. Diluting the solution does not influence the value of n. n = 0.03375\;\text{mol} for the diluted solution.
  • Volume of the diluted solution: 25\;\text{mL} + 135\;\text{mL}  = 160\;\textbf{mL} = 0.160\;\textbf{L}.

Concentration of the diluted solution:

\displaystyle c = \frac{n}{V} = \frac{0.03375\;\text{mol}}{0.160\;\textbf{L}} = 0.021\;\text{mol}\cdot\textbf{L}^{-1} = 0.021\;\text{M}.

The least significant number in the question comes with 2 sig. fig. Keep more sig. fig. than that in calculations but round the final result to 2 sig. fig. Hence the result: 0.021 M.

Which one of the following chemicals is most likely coming from the gas stove?
Eva8 [605]
Here's a hint. One of these is a liquid, one is a gas, and one is a radioactive gas. Match each of these descriptions to the right element, and tell me which one you would be most likely to be emitted from your stove.
