In order to apply the principle of conservation of mass to this reaction, we must prove that the mass on the left hand side is equivalent to the mass on the right hand side. In order to do this, we must first acquire the atomic masses of each substance involved. These are:
Fe - 56
O - 16
Now, we substitute these values into the equation:
4(56) + 3(2*16) = 2(56 * 2 + 16 * 3)
224 + 96 = 320
320 = 320
As we can see, the principle of conservation of mass holds true.
Ice floats because it is about 9% less dense than liquid water. ... The heavier water displaces the lighter ice, so ice floats to the top. One consequence of this is that lakes and rivers freeze from top to bottom, allowing fish to survive even when the surface of a lake has frozen over
The molar volume of the gas : V = 447.993 L
<h3>Further explanation</h3>
Given
n = 1 mol
P = 0.05 atm
T = 273 K
Required
The molar volume
Solution
Ideal gas law :
PV=nRT
V = nRT/P
Input the value :
V = 1 x 0.08205 x 273 / 0.05
V = 447.993 L
