I think it is B silicon and iron.
Answer:
The temperature of the gas after it is filled is 596 K
Explanation:
According to Gay-Lussac law, the pressure of a gas mass is directly proportional to temperature to a constant volume. That means than if pressure rise, the temperature too. We can assume then the volume is constant because the tank is isolated. The tank will be full when pressure will be in equilibrium, that means when pressure will be 1 atm because it is environment pressure. Using the following equation:
P1 /T1 = P2 /T2 and replacing, T2 = P2 *T1 / P1 = 1 atm * 298K / 0.5 atm = 596 K.
I hope my answer helps you
Im not sure how correct these are but i hope they help :)
some potential barriers are
youd have to wait for the chemicals to clear up before goiun gback into that room if u have kids that r little you would have to make sure they dont lick wutever it is u cleaned otherwise it might poison them and if u use to much of it it could make the air poisoness for a few which could be dangerous toi breathe in.
again im not to sure how correct these r but i hope they were right and i hope they help :)
<span>They haven't figured out a position to put hydrogen in yet. Some elements are chemically similar yet placed in different groups. It doesn't have space for the f block in the main composition of the table.Group VIII B is comprised of 3 columns, instead of the more space efficient one.</span>
Answer: The pH of a 0.00250 M oxycodone solution is 9.96
Explanation:

cM 0 M 0 M

So dissociation constant will be:

Give c= 0.00250 M and
= 5.47


Putting in the values we get:


![[OH^-]=c\times \alpha](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3Dc%5Ctimes%20%5Calpha)
![[OH^-]=0.00250\times 0.0369=9\times 10^{-5}](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D0.00250%5Ctimes%200.0369%3D9%5Ctimes%2010%5E%7B-5%7D)
Also ![pOH=-log[OH^-]](https://tex.z-dn.net/?f=pOH%3D-log%5BOH%5E-%5D)
![pOH=-log[9\times 10^{-5}]=4.04](https://tex.z-dn.net/?f=pOH%3D-log%5B9%5Ctimes%2010%5E%7B-5%7D%5D%3D4.04)


Thus pH of a 0.00250 M oxycodone solution is 9.96
