Answer:

I believe it's plasma, solid, liquid, gas.

Explanation:

<h2>plasma and solids consist of lots, one jumbled, one together. liquid is still quite a bit, and gas is everywhere but there isn't much in one.</h2>

A gas has a volume of 3.25 liters at 54 C and 231 kPa of pressure. At what temperature will the same gas take up 4.35 liters of

Firdavs [7]

Answer: 318 K

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 231 kPa

$P_2$ = final pressure of gas = 168 kPa

$V_1$ = initial volume of gas = 3.25 L

$V_2$ = final volume of gas = 4.35 L

$T_1$ = initial temperature of gas = $54^oC=273+54=327K$

$T_2$ = final temperature of gas = ?

Now put all the given values in the above equation, we get:

$\frac{231\times 3.25}{327}=\frac{168\times 4.35}{T_2}$

$T_2=318K$

At 318 K of temperature will the same gas take up 4.35 liters of space and have a pressure of 168 kPa

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

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

an atom has 79 protons, 78 electrons and a mass number of 118. how many neutrons does this atom have

igomit [66]

Answer:

Explanation:

Electrons weigh almost nothing, so their mass doesn't really matter for these types of problems. Just subtract 118-79 to find the remaining mass which is for the neutrons.
