That would be mechanical because you're not changing the substance only the appearance.
Answer:
2.23 x 10^-4 mol
Explanation:
0°C =273 K
PV= nRT
n= PV/RT
n= (5.00 atm * 0.0010 L)/ (0.0821 * 273 K)
n= 2.23 x 10^-4
Answer:
Option (2) At equilibrium, there is a much higher concentration of products than reactants.
Explanation:
The equilibrium constant for a reaction is simply the ratio of the concentration products raised to their mole ratio divided by the concentration of the reactants raised to their mole ratio.
If the equilibrium constant is close to 1 or 1, it means the concentration of the reactants and products are almost the same. But if the equilibrium constant is large as in the case of the question given above, it means that at equilibrium, the concentration of the products are higher than that of the reactants.
Answer:
See explanation below
Explanation:
Water has the anomality of having the solid less dense than the liquid state. The reason for this is that the hydrogen bonds in the solid ice forces the molecule to occupy more room to properly have the stability afforded by the hydrogen bonds. That is the reason why ice floats on water.
The other interesting consequence of this anomality is that the slope of the solid/liquid phase boundary is negative since at higher pressures the ice can be changed to its liquid phase which can be seen from the negative slope of the solid/liquid boundary.
A) True
B) False
C) False
D) True
E) False
F) True close up to 4 ºC when the water molecules start to behave like other liquids, that is the density of the liquid decreases.
G) True
H) True ( repeated question)
