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
Answer:
i think the answer is the last one.
The water molecules move by active transport into the cell from high water concentration to low water concentration.
Explanation:
The density of substance that contain 850 milligrams for every Ml is
0.85 g/Cm³
calculation
<em> </em><em>step 1:</em><em>convert 850 Mg to g</em>
<em>that is 1 mg=0.001 g</em>
<em> 850 mg =? g</em>
<em>= (850 mg x 0.001 g)/ 1 mg=0.85 g</em>
<em>step 2: convert Ml to Cm³</em>
<em> that is 1 Ml = 1 cm³</em>
<em>therefore density =</em><em> 0.85 g/Cm³</em>
''Find the density of the plastic and compare it to the density of water''
