Answer:
though many may argue that cake batter is a homogeneous mixture because of its observable uniformity, we know it is heterogeneous. ... In other words, the mixture of ingredients from cake batter results in some chemical reactions here and there, but we are still left with a mixture of things that can be separated.
Explanation:
A cell is made of molecules and a molecule is made of atoms. That's the simplest way of putting it. More complicated is that a cell is made up of macromolecules, such as proteins, lipids, etc. A molecule is a particular configuration of atoms.
Answer:
130 Liters
Explanation:
if 1 mol is 22.4 L, then 5.8 mol is 130 L (129.92 but use sig figs)
Answer:
gas molecules scatter short wavelengths of light (blue and violet) more than long (red and orange) so the sky looks blue. at sunrise and sunset, the light passes through thicker atmosphere and blue light is scattered more, so mostly red and orange light is visible.

Answer:
P[H2] = P[I2] = 0.02 atm
P[HI] = 5.98 atm
Explanation:
The ICE table for the given reaction is:
H2(g) + I2(g) ↔ 2HI(g)
Initial 3.01atm 3.01atm -
Change -x -x +2x
Equilib (3.01-x) (3.01-x) 2x
The equilibrium constant, Kp is given as:
x = 2.99 atm
Equilibrium partial pressure of H2 = I2 = 3.01-2.99 = 0.02 atm
Equilibrium partial pressure of HI = 2x = 2(2.99) = 5.98 atm
