Answer:

No, Stephanie is incorrect. Formation of petroleum cannot take place under the presence of oxygen.

Explanation:

Since, the petroleum is fossil product. Fossil fuel are formed under high pressure and temperature with absence of oxygen for longer period. so the way she is performing is completely incorrect. With the presence of oxygen in no way petroleum will be formed. The temperature and pressure should be in different combination for the formation of the petroleum. Along with the layers of sediments to maintain the pressure is required.

Answer:

Sample Response: Stephanie is incorrect, because fossil fuels form in the absence of oxygen. If oxygen is present, they cannot form.

Answer:

4 people

Explanation:

In order to know this, we need to gather the data.

First we have 3.5x10⁴ g of LiOH. This grams are to be last for the whole 9 days mission shuttle.

So, we first need to know how much of CO₂ will be neutralized by this mass. This can be done calculating the moles of LiOH, and then, the moles of CO₂

The molecular weight of LiOH is 23.94 g/mol and for CO₂ is 44 g/mol so:

CO₂ + 2LiOH -------> Li₂CO₃ + H₂O

moles of LiOH = 3.5x10⁴ / 23.94 = 1461.988 moles

We have a mole ratio of 1:2 so the moles of CO₂:

moles CO₂ = 1461.988 / 2 = 730.994 moles

The mass of CO₂ for the 9 days will be:

m CO₂ = 730.994 * 44 = 32163.74 g

Now, let's see how much it has to be used per day:

m CO₂/d = 32163.74 / 9 = 3573.75 g per day

This means that we can only take a few astronauts, and this number is:

n° astronaut = 3573.75 / 8.8x10²

<h2>n° astronaut = 4.06</h2><h2>In other words, only 4 astronaut</h2>

scoundrel [369]
I think the correct answer would be NH4ClO4. It would produce a basic solution since as it dissociates into ions OH ions are being formed as the concentration of this increases, the pH of the solution would increase as well making it basic. Hope this helps.
