Question

Question 26 (1 point) If the volume of a sample of Ne is doubled by a temperature change at constant pressure, what must have happened to the temperature (in K)? O It stayed the same lt tripled It went down to 1/3 It went down to 1/2 It doubled Question 27 (1 point) Which technique listed below separates a mixture of liquids on the basis of their boiling points? Odecantation filtration fractional crystallization distillation drinking Question 28 (1 point) Based on hydrogen-bonding, which of the following is likely to have the greatest viscosity? Formaldehyde, H2CO Dimethy ether, H3C-O-CH3 Methanol, CH3OH Benzene, CoHo Water, H20

Aplogies. Hello If you could Answer all that would be Super helpful! thanks!

Answer 1

26 F the volume of a sample is doubled by a Tempreature changed (Pressure constant) then, V&T (Charles laul) The Tempreature is doubled. The techniques used to seprate mixture - (27) f their boiling on the basis o distillation . points - (28) Based on Ha Bonding - the greatest viscosity is methanol (eth oH) (99) Greatest amount of melting of 1kg ice.
