Silicon generally forms at least polar covalent bonds, like carbon, as befits its status as a Gropu 4A nonmetal. The only obvious exception I can think of is SiC, which despite the similarity you might expect to graphite or diamond does, I think, have significant ionic or metallic character to its bonding in the solid state.
It would had to have melted in order to change the properties from a solid into a liquid. It also depends on the type of solid wheither a chemical or a ice cube. If it was a ice cube if would dilutte the liquid solution and changes the taste ot texture (feel) if it was a chemical the properties could change the liquid into a solid only depending on th type of chemical. EX..Liquid Nitrogen and a piece of raw chiken the outcome after putting the chicken in the nitrogen would be frozen. Because the chemical Nitrogen freezes the particles which makes the chicken frozen.
Answer:
To express the efficiency of a reaction, you can calculate the percent yield using this formula: %yield = (actual yield/theoretical yield) x 100. A percent yield of 90% means the reaction was 90% efficient, and 10% of the materials were wasted (they failed to react, or their products were not captured).
Explanation:
The hydrogen bonds is an intermolecular force.
This is, it is an atracction among molecules, which trends to keep the molecules close one to each other quite strongly.
Vaporization is the pass from liquid, where the molecules are pretty close one to each other, to gas, where the molecules are more distant from each other. To reach that separation of the molecules, the strong hydrogen bonds must be overcome, which means a higher energy requirement than in similar compounds without hydrogen bonds.
That is reflected in high values for the enthalpy of vaporization in the compounds with hydrogen bonds (like hydrogen halides).
So, that leads to the option D. of the list of answers. enthalpy heat of vaporization gives the best indication of the relative strenght of hydrogen bonds.
