Volumen = constant => P/T = constant
T1 = 21°C + 273.15 = 294.15 k
P1 = 0.82 atm
T2 = - 3.5°C + 273.15 = 269.65 k
P2 = ?
P2 / 269.65k = 0.82atm / 294.15k
P2 = [0.82atm / 294.15k] * 269.65kg = 0.75 atm
Scientists use models to show the characteristics of compounds. Of the different models,ball-and-stick model and space-filling model are commonly used but similar. Ball-and- stick model shows the bond between both atom and not the relative size of the atoms. Space-filling model shows the relative size of the atom and not the bond between the atoms. Both are 3-Dimensional and use color spheres within the model.
Hey there!
5 moles will be produced.
N₂ has a molar mass of 28.014 g/mol.
Convert 70g to mol:
70 ÷ 28.014 = 2.5
In N₂ there are 2 nitrogen atoms. In NH₃ there is 1 nitrogen atom.
So, there will be twice as many moles of NH₃ because every one molecule of N₂ will produce two molecules of NH₃.
2.5 x 2 = 5 moles
Hope this helps!
The answer is C. because the dwarf planet's orbit lies between mars and Jupiter but it orbits the sun. Hope it helped!

lol i hope i’m not too late
