Saturn and Jupiter are similar to the sun and aren’t solid , while Earth, Moon, and Mars are made of rock which makes it have more compositions. It’s just the way the planets were made.
Hopefully this helps you! If not I’m sorry :(
There are 0.400 mol Br₂ in the sample..
Mass of Br₂ = 20.5 mL Br₂ × 3.12 g Br₂/1 mL Br₂ = 63.96 g Br₂.
Moles of Br₂ = 63.96 g Br₂ × (1 mol Br₂/159.81 mol Br₂) = 0.400 mol Br₂
Let's look at the molar weight of the answers:
NO is 30 g/mol
NO2 is 46
N2O is 44
N2O4 is 124
<span>We have the grams of the product, so we need the moles in order to calculate the molar weight. We us PV=nRT for this, assuming standard temperature and pressure. </span>
You were given the liters (.120L)
Std pressure is 1 atmosphere
You're looking for n, the number of moles
<span>Temp is 293.15 kelvin, thats standard </span>
And r is the gas constant in liters-atm per mol kelvin
(.120 liters)(1atm)=n(293.15K)(.08206)
Solving for n is .0049883835 mol
<span>.23g divided by .0049883 mol is about 46g/mol. You're answer is B I think, NO2
I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer:
It will be C.
Explanation: If you read all of the other choices closely they don't make sense in context. (Option A) wouldn't make sense because removing things that could be reused would be inefficient to the body (and waste can't typically be reused in the human body). (Option B) growing too tall isn't particularly healthy or helpful, but it's not exactly life threatening either. And the very last choice is just nonsense period.
