Covalent
bonds = sharing of electrons between two atoms of the same elements or elements
close to each other on the periodic table. Usually they are metals sometimes
non-metals. In polar bonds electrons are
shared unequally. Non polar bonds share electrons equally.
Ductility - a materials ability to stretch, ie if you pull it apart does it stretch to a wire.
density - ratio of volume to mass
conductivity - materials ability to conduct a current.
hopefully with these definitions you can figure out the answer.
Out of the options, glass is the least fluid. The proof of this also lies in the fact that glass is the most difficult to melt out of all of the mentioned substances, and melting point gives us a rough estimate of the strength of intermolecular forces.
Answer:
Explanation:
Molal freezing point depression constant of butanol Kf = 8.37⁰C /m
ΔTf = Kf x m , m is no of moles of solute per kg of solvent .
mol weight of butanol = 70 g
235.1 g of butanol = 235.1 / 70 = 3.3585 moles
3.3585 moles of butanol dissolved in 4.14 kg of water .
ΔTf = 8.37 x 3.3585 / 4.14
= 6.79⁰C
Depression in freezing point = 6.79
freezing point of solution = - 6.79⁰C .
Answer:
Double replacement.
Explanation:
Chemical Reactions => Double Replacement Reactions.
Let's call Ted as T, Emily as E, Jack as J, and Brenda as B.
In the first match, we have T and E playing against J and B; and in the second match, we have T and B playing against J and E. We can state a 'reaction' of this if the first match would be the reactants and the second match the products:
You can note that this is similar to a double replacement reaction, remember that a double-replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds. The general form of a double-replacement reaction is:
which is similar to the reaction of the game, so the answer would be Double replacement.
