The graph that shows that gases become increasingly soluble in a liquid as the temperature of the liquid decreases is a graph that shows these characteristics:
1) vertical-axis (traditional y-axis): solubility
2) horizontal-axis (traditional x-axis): temperature
3) graph: a curve with negative slope, i.e. the as the temperature (horizontal-axis) goes further to the right (increasing), the solubility (vertical-axis) goes downward.
An example of the application of this property is the CO2 in the sodas. CO2 incorporated at low temperature.
Answer:
When the solution (with phenolphthalein) changes to colorless
Explanation:
When titrating with HCl is common to add phenolphthalein as an acid-base indicator.
Phenolphthalein is pink or fucsia when added into a basic solution. On the other hand when it is in acid solutions, is colorless.
So, when titrating, the NaOH solution will be initialy pink due to the phenolphthalein and when reaching the equivalence point, that color will fade out into colorless. This is how you know you hace reached the equivalent point.
Answer:
578.04 °C
Explanation:
The temperature is given in Kelvin which has value = 304.89 K
Kelvin and Celsius are both units of the temperature which can be incontrovertible.
The conversion of T(K) to T( °C) is shown below:
T( °C) = T(K) - 273.15
Given that = T(K) = 304.89
So,
T = (304.89 + 273.15) °C = 578.04 °C
<u>The temperature in degrees Celsius is 578.04 °C . </u>
