Precipitate the reactants in achemical reaction. II. TRUE or FALSE. Write TRUE if the statement is correct and FALSE if it is not.
21. Sugar is very soluble in a nonpolar liquid like mineral oil.
22. Acetone has a higher vapour pressure than ethanol.
23. In a water molecule, the hydrogen is partially positive, while the oxygen is partially negative.
24. The stability of the DNA structure arises from the H-bonding of base pairs.
25. Components of electronic devices include nonpolar substanceslike transient suppression diodes, metalloids and semimetals.
26. Vapour pressure rises as the strength of IMFA decreases.
27. Boiling point, melting point, viscosity ang surface tension increases as the strength of IMFA decreases.
28. lon-dipole interaction exists between ions and a nonpolar compound. 29. Hydrogen bonding occurs with polar molecules bonded with highly- electronegative atoms.
30. Water is a polar molecule, thus it is miscible with nonpolarmolecule like oil.
