Answer:
The answer to your question is: V = 6.93 L
Explanation:
Data
N₂ = 5.6 g
Volume of NH₃ = ?
14 g of N ---------------- 1 mol
5.6 g ----------------------- x
x = (5.6 x 1) / 14 = 0.4 mol of N
Reaction
N₂ + 3H₂ ⇒ 2NH₃
1 mol of N₂ ---------------- 2 moles of NH₃
0.4 mol of N₂ -------------- x
x = (0.4 x 2) / 1
x = 0.8 mol of NH₃
Formula
PV = nRT
P = 5200 torr = 6.84 atm
V = ?
n = 0.8
R = 0.082 atm L/ mol °K
T = 450°C = 723°K
Substitution
V = (0.8)(0.082)(723) / 6.84
V = 6.93 L

Answer:
volume=0.4ml
Explanation:
use the equation
n=c×v. first make v become the subject of the formula by dividing c on both sides of the equation
v=n/c
v=0.100÷2.5×10^-2
v=4×10^-4
v=0.0004L
now convert 0.0004L to ml by multiplying 0.0004 with 1000 to get 0.4ml
therefore the volume in ml is 0.4ml

Explanation:
add both because there both forces are going down
Answer:
No
Explanation:
The moon has no atmosphere, because it is a giant space rock that somehow managed to land in earth's orbit and gravitational pull of force.
Answer:
Buoyant objects will bob up and down from the waves, the forces put on said buoyant object can be converted to more useful forms to do work.
