What is the mole fraction of water in pure water
irinina [24]
In pure water, all of the molecules in the liquid are water molecules so the mole fraction is 1 (100 % H2O, 55 mol/L). In sea water, the concentration of water molecules in the solution is less than that of pure water so the vapor pressure of sea water is also lower.

A battery can provide a current of 4.60 A at 3.40 V for 2.50 hr. How much energy (in kJ) is produced? 1st attempt kJ Energy
Lunna [17]

Answer:

The energy produced equals 140.760 kJ

Explanation:

The relation between power, current and voltage is

Power=Current\times Voltage

Applying the given values in the relation above we get

Power=4.60\times 3.40=15.64W

Now Since Power=\frac{Energy}{Time}\\\\Energy=Power\times Time

Again applying the calculated values we get

Energy=15.64\times 2.50\times 3600=140760Joules=140.76kJ

The term that best describes a 10-gram of KCIO3 per 100 grams of water solution at 30 degrees celsius is:
In-s [12.5K]
The term that best described a 10 gram of KClO3 per 100 grams of water solution at 30 degree Celcius is Saturated. The solubility chart is needed for this work. If the solubility chart is drawn for KClO3, it will be observed that the proportion of KClO3 that is needed to dissolve in 100ml of water to make the solution saturated is 10 grams at 30 degree Celcius.
