Long term because if you leave something out to be weathered then it can’t be unweathered because of the drastic change of the object.
Um okay so I'm not 100 percent sure so I asked Google and it said the answer is genes.
Answer:
initial temperature=![-3.31^{\circ}C](https://tex.z-dn.net/?f=-3.31%5E%7B%5Ccirc%7DC)
Explanation:
Assuming that the given follows the ideal gas nature;
![P_1=0.723atm](https://tex.z-dn.net/?f=P_1%3D0.723atm)
![V_1=13.5L](https://tex.z-dn.net/?f=V_1%3D13.5L)
![T_1=?](https://tex.z-dn.net/?f=T_1%3D%3F)
![P_2=0.612atm](https://tex.z-dn.net/?f=P_2%3D0.612atm)
![V_2=17.8L](https://tex.z-dn.net/?f=V_2%3D17.8L)
![T_2=28 ^{\circ}C =273+28K=301K](https://tex.z-dn.net/?f=T_2%3D28%20%5E%7B%5Ccirc%7DC%20%3D273%2B28K%3D301K)
mole of gass will remain same at any emperature:
![\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BP_1V_1%7D%7BT_1%7D%20%3D%5Cfrac%7BP_2V_2%7D%7BT_2%7D)
putting all the value we get:
![T_2 =269.7K =-3.31 ^{\circ} C](https://tex.z-dn.net/?f=T_2%20%3D269.7K%20%3D-3.31%20%5E%7B%5Ccirc%7D%20C)
initial temperature=![-3.31^{\circ}C](https://tex.z-dn.net/?f=-3.31%5E%7B%5Ccirc%7DC)
Answer:
D.
Explanation:
Inverse and proportional means as one goes up the other goes up or if one goes down the other goes down.

The question says only to convert the Zn(OH)₂ into moles. But the given answer has many errors such as formula, mass and moles.
<span>The corrected answer is as follows.
</span>Moles (mol) = mass (g) / molar mass (g/mol)
<span>
</span><span>Mass of Zn(OH)₂</span><span> = 0.45 g
Molar mass of Zn(OH)₂ = </span><span>99.424 g/mol
</span>Hence, moles of Zn(OH)₂ = 0.45 g / 99.424 g/mol
<span> = 4.526 x 10⁻³ mol
