Temperature is the correct answer.
Temperature is actually a degree of hotness or coldness which can be measured by using a scientific instrument called thermometer. The above situation in the question refers to the daily cold in the winter which shows the daily weather expressed here is temperature and not wind or winter itself.
Answer:
It is a proposed explanation for a phenomenon.
Answer: 0.100 m
Explanation:
= Elevation in boiling point
i = Van'T Hoff factor
= boiling point constant
m = molality
1. For 0.100 m
i= 3 as it is a electrolyte and dissociate to give 3 ions.
Thus concentration of ions =
2. For 0.100 m
i= 2 as it is a electrolyte and dissociate to give 2 ions.
Thus concentration of ions =
3. For 0.200 m
i= 1 as it is a non electrolyte and do not dissociate to give ions.
4. For 0.060 m
i= 4 as it is a electrolyte and dissociate to give 4 ions.
Thus concentration of ions =
Thus as concentration of ions is highest for and the boiling point will be highest.
Arm. The center is the yellow, in the very middle. I hope this helps.
6.667 moles
Molar mass H3PO4 is 98 g/mol
mass of H3PO4 = 98 x 6.667 = 653.4g
mass of Cu = 27 , moles of Cu = 27 / 63.5 = 0.425
moles of Cr produce this Cu = .425 x 2/3 = 0.283 moles
or 0.283 x 52 = 14.7g
