if an atom of polonium-218 were to undergo alpha emission, followed by two beta emissions, which nuclide would result? lead-214

tia_tia [17]

Po, (218, 84) - Alpha Particle (4, 2) = (218 - 4, 84 - 2) = <span>(214 , 82)</span>

(214 , 82) - 2Beta = (214, 82 - 2*(-1)) = (214 , 84)

Polonium has atomic number of 84.

So answer = Polonium-214

If the number of moles of a gas initially contained in a 2.10 l vessel is doubled, what is the final volume of the gas in liters

Anon25 [30]

Avagadro's law gives the relationship between volume of gas and number of moles of the gas. When the temperature and pressure are constant, volume is directly proportional to number of moles of gas.
$\frac{V1}{n1} = \frac{V2}{n2}$
V -volume and n - number of moles of gas.
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
initial number of moles n1 - N
n2 - 2N as the number of moles are doubled
V1 - initial volume - 2.10 L
V2 - final volume - V
substituting the values in the equation
$\frac{2.10L}{N} \frac{V}{2N}$
V = 4.20 L
final volume is 4.20 L

The chemical force for which of the following ions is directed into the cell? The chemical force for which of the following ions

Over [174]

Answer:

Both sodium and calcium.

Explanation:

The membrane potential is maintained inside and outside of the cell due to the unequal distribution of the different ions. This membrane potential difference is important for the generation of action potential.

The resting membrane potential is around +30 mV. This is due to the presence of potassium ions. The sodium and calcium ions must enter in the cell to change this membrane potential and generates the action potential in the body.

Thus, the correct answer is option (3).
