Answer:

3.23 atm

Explanation:

Use the equation P₁V₁=P₂V₂. P₁ and V₁ are initial pressure and volume. P₂ and V₂ are final pressure and volume. Solve for P₂.

(1.88 L)(3.81 atm) = (2.22 L)(P₂)

7.1628 L*atm = (2.22 L)(P₂)

P₂ = 3.226 atm

Flourine is found to undergo 10% radioactivity decay in 366 minutes determine its halflife

yuradex [85]

Answer:

$\boxed{\text{2408 min}}$

Explanation:

The integrated rate law for radioactive decay is

$\ln\dfrac{N_{0}}{N_{t}} = kt$

1. Calculate the decay constant

$\begin{array}{rcl}\ln \dfrac{100}{90} & = & k \times 366\\\\1.054 & = & 366k\\\\k & = & \dfrac{1.054 }{366}\\\\k & = & 2.879 \times 10^{-4} \text{ min}^{-1}\\\end{array}\\\\$

2. Calculate the half-life

$t_{\frac{1}{2}} = \dfrac{\ln2}{k}\\\\t_{\frac{1}{2}} = \dfrac{\ln2}{2.879 \times 10^{-4} \text{ min}^{-1}} = \text{2408 min}\\\\\text{The half-life for decay is } \boxed{\textbf{2408 min}}$

You are at home in your air conditioned garage. You are planning a family road trip from New York to Florida. You are lnfating t

Ksenya-84 [330]

Hello!

According to the Charles' Law, the volume of a gas is proportional to temperature when pressure is constant. When going from New York to Florida, if the pressure is left constant the volume of the tires will increase.

The final volume of the tires can be calculated from the following equation, derived from Charles' Law:

$V2= \frac{V1}{T1}*T2=\frac{10 L}{10degC}*32degC=32 L$

Have a nice day!
