Write the nuclear equation for the beta decay of Aluminum-25.
Brums [2.3K]

We want to write the nuclear equation for the beta decay of Aluminium-25.

The equation is:

^{25}_{13}Al \implies ^{25}_{14}Si +   ^{0}_{-1}e

First, as you may know, in a beta decay the number of protons is increased by one. Aluminium has 13 of them, so after the decay, we will have 14 protons.

This means that the aluminium will transform into silicon, then the nuclear equation is just:

^{25}_{13}Al \implies ^{25}_{14}Si +   ^{0}_{-1}e

Where the:

^{0}_{-1}e

Is an electron, which is the emitted particle in the beta decay.

A pump contains 1.5 L of air at 175 kPa. You draw back on the piston of the pump, expanding the volume until the pressure reads
Tresset [83]

Answer:

\large \boxed{\text{86.8 L}}

Explanation:

The temperature and amount of gas are constant, so we can use Boyle’s Law.

p_{1}V_{1} = p_{2}V_{2}

Data:

\begin{array}{rclrcl}p_{1}& =& \text{0.579 atm}\qquad & V_{1} &= & \text{150 L} \\p_{2}& =& \text{1.00 atm}\qquad & V_{2} &= & ?\\\end{array}

Calculations:  

\begin{array}{rcl}0.579 \times 150 & =& 1.00V_{2}\\86.85 & = & 1.00V_{2}\\V_{2} & = &\dfrac{86.85}{1.00}\\\\& = &\textbf{86.8}\\\end{array}\\\text{The new volume of the gas is } \large \boxed{\textbf{86.8 L}}
