Hello there!
In this case, for this chemical equilibrium problem, it turns out possible for us to solve for the equilibrium concentrations by firstly setting up the equilibrium expression:
Thus, by plugging in an ICE chart, in terms of x (reaction extent), we can write:
And could be solved for x as follows:
Therefore, the equilibrium concentrations turn out to be:
Regards!
Answer:
for the first question, the context is necessary in order to answer...
Fat is immiscible (does not mix) with water because fat is nonpolar and water is polar (remember like dissolves like: polar mixes with polar, nonpolar with nonpolar).
soap bubbles by having many soap molecules surround fat molecules with their nonpolar end, and direct their polar ends outwards.
For your second question:
Dirt and oil are nonpolar. When we wash our bodies with water (which is polar) it does not do a good job in removing these nonpolar molecules. Soap, on the other hand, has a long nonpolar end and a small polar end. The nonpolar end of the soap molecule attaches to the dirt and oil on your skin and when the water from the shower head hits the soap, it pulls the dirt, oil, and soap off of you by attaching itself to the polar end of the soap molecule.

Answer:
2 g
Explanation:
Since both sides have to be equal, add together the weight from the left side to get the total of 137
Subtract 135 from that
The answer is 2.
Answer:
7.5 × 10¹⁵ Hz
Explanation:
Given data
- Wavelength of the radio waves (λ): 40 nm = 40 × 10⁻⁹ m = 4.0 × 10⁻⁸ m
- Frequency of the radio waves (ν): ?
- Speed of light (c): 3.00 × 10⁸ m/s
We can determine the frequency of the radio waves using the following expression.
c = λ × ν
ν = c/λ
ν = (3.00 × 10⁸ m/s)/4.0 × 10⁻⁸ m
ν = 7.5 × 10¹⁵ s⁻¹ = 7.5 × 10¹⁵ Hz
Answer:
Because the atmospheric pressure at higher altitudes is lower than at sea level.
Water, or any liquid for that matter, boils when its vapor pressure equals the external pressure above the liquid.
