Beryllium-8 decays through the release of an alpha particle. Draw what the nucleus would look like after an alpha particle is emitted. What element does it become?

Explanation:

Beryllium-8,⁸Be, undergoes alpha decay through the equation shown below

₄⁸Be - ₂⁴He ⇒ ₂⁴He

Hence, after an alpha decay, beryllium becomes alpha particle (helium) itself with it's nucleus shown in the attached picture. Generally, beryllium undergoes a double alpha decay as shown in the reaction below

₄⁸Be ⇒ ₂⁴He + ₂⁴He

Combustion is the act or process of burning. therefore, i believe the answer is  a: burning wood. 

We first assume that this gas is an ideal gas where it follows the ideal gas equation. the said equation is expressed as: pv = nrt. from this equation, we can predict the changes in the pressure, volume and temperature. if the volume and the temperature of this gas is doubled, then the pressure still stays the same.
