Answer:
Explanation:
Hello,
In this case, for the considered reaction, the standard reaction entropy is computed considering the standard entropy of each product and reactant and their stoichiometric coefficients as shown below:
Thus, considering the ALEKS Data tab, we obtain:

<span>Some criminals are rational. Some are driven by psychological and emotional factors. Some are a combination. There is no single source of motivation that drives all criminals.
Let us look, for example, at a young man from a very poor neighborhood who becomes a drug dealer and perhaps an occasional thief or mugger. He may be acting in part rationally. He may believe that he has needs that he wants to fullfill</span>
Answer:
Kc = 105062.5 at 298K
Explanation:
First of all, we state the equilibrium:
3O₂(g) ⇄ 2O₃(g)
We know data about equilibrium concentration of oxygen. We suppose 1 mol of oxygen at the begining. During the reaction, x moles have reacted.
As ratio is 2:3, we can determine how many moles of ozone have been produced.
(x . 2)/3
So we have the final concentration of oxygen, so, let's find out x
1 - x = 0.016 moles
x = 0.984 moles
Then, the [O₃] in equilibrium will be (0.984 . 2) /3 = 0.656.
We supose a volume of 1 L, so we have molar concentration to determine Kc. Let's state the expression for it:
Kc = [O₃]² / [O₂]³
Kc = 0.656² / 0.016³ → 105062.5
The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol). The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms.
Answer: Option C.
The waste from these plants is safe, and its storage and disposal are simple
Explanation:
Nuclear power plants produce waste when producing electricity and these waste are not really harmful as you think, they are stored well before disposing appropriately.
Once the waste is removed the reactor, the wastes are cool down in storage pool, they are moved to dry caske which is a concrete storage and stores it for a long time and can be dispose until the site is available for it.
