Answer:
See explanation for solution
Explanation:
Mass fraction × 100= percent
Mass fraction of Nitrogen = 78/100= 0.78
Mass fraction of Oxygen= 20/100= 0.20
Mass fraction of Water vapour = 2/100=0.02
Answer : The number of sodium ions is equal to the number of formula units of salt.
Explanation : In the given reaction of NaCl the statement which describes it the best is that the number of sodium ions is found to be same along with the formula units in the product side.
+ ----> NaCl.
Its clear from the equation that one mole of Na and one mole of Cl combines together to give the product, which is one mole of NaCl. The number of ions on both the sides are equal.
fractional distilation because the solvent will evaporate and pass through the condenser and the sonvent will be in the beaker while the solute remains in the round bottomed flask
Waterways or lakes. at least that’s what google said lol.
<span>Answer: at 0.01 °C and 0.0060 atm the three phases (solid, liquid and gas)

</span><span>1) Water at 0.0060 atm and 0.01° C is at its triple point.
</span>
2) The triple point is the point in the phase diagram at which the three physical states coexist: gas, liquid and solid.
3) That means that water can freeze and boil at the same time. In fact they can happen any of the six changes of phase: freezing (liquid to solid), melting (solid to liquid), evaporation (liquid to gas), condensation (gas to liquid), sublimation (solid to gas), and deposition (gas to solid).
The phase diagram is unique for any substance, meaning that it is different for different substances: the normal boiling and melting points are different.
