Polonium-218 undergoes beta decay, converting a neutron into a proton. Then the daughter isotope undergoes another beta decay, a

sergij07 [2.7K]

Answer: $^{218}_{84}Po \rightarrow ^{218}_{85}At + ^{0}_{-1}e$ is the correct equation for beta decay.

Explanation:

When a beta particle, that is, $^{0}_{-1}e$ is emitted in a radioactive decay then it is known as beta decay.

Therefore, beta decay of Polonium-218 is as follows.

$^{218}_{84}Po \rightarrow ^{218}_{85}At + ^{0}_{-1}e$

Therefore, we can conclude that $^{218}_{84}Po \rightarrow ^{218}_{85}At + ^{0}_{-1}e$ is the correct equation for the given beta decay.

A gas with a volume of 4.0L at a pressure of 205kPa is allowed to expand to a volume of 12.0L. What is the pressure in the conta

mr Goodwill [35]

Answer:

68.3 kilo Pascal is the pressure in the container.

Explanation:

To calculate the new pressure , we use the equation given by Boyle's law. This law states that pressure is inversely proportional to the volume of the gas at constant temperature.

The equation given by this law is:

$P_1V_1=P_2V_2$
