Correct me if I'm wrong, anyone who is more informed on this than I am, but wouldn't it be because of the magnetic fields and whatnot? The longer I think on it, the more I feel like I'm wrong, so don't take my word for it 100%

Lady bird [3.3K]

Answer:

0.41kg/sec

Explanation:

PV= nRT

Given : V= 505 L

P=0.88 atm

R= 0.08206 Latm/K*mol

T= 172 .0C = 172+273 = 445 K

n = PV /RT = 0.88 * 505 / 0.08206 * 445 = 12.17 moles per sec of N2 are consumed

As per reaction : N2 + 3H2 ----> 2NH3

1 mole N2 is consumed to produce 2 moles NH3

moles of NH3 produced per sec :

(2 moles NH3/1mol N2) * 12.17 moles N2 = 24.34 moles NH3 per sec

grams of NH3 produced per sec =

24.34 moles NH3 per sec * molar mass NH3 = 24.34 moles NH3 per sec * 17.031 g/mol = 414.5 g NH3 per sec

rate in Kg/sec = 414.5 g NH3 per sec * (1kg /1000g) = 0.4145 Kg/sec

= 0.41kg/sec

an irregularly shaped solid is dropped into a graduated cylinder filled with 45.00 mL of water. the water level with the object
posledela

The density of the object is 1.96 g/cm³.

Mass = 73.5 g

Volume = 82.5 mL – 45.00 mL = 37.5mL = 37.5 cm³

Density = mass/volume = 73.5 g/37.5 cm³ = 1.96 g/cm³
