It seems that you have missed the necessary table for us to answer this question, so I had to look for it. Anyway, here is the answer. <span>Based on Table S, an atom of the element POLONIUM has the weakest attraction for electrons in a chemical bond. Hope this answers your question.</span>
A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in another
Answer:
Explanation: In a chemical formula, the symbols for each element in the compound are followed by subscripts that tell us how many of that element are in the compound. The subscripts that follow each element's symbol indicate how many of that element are in the compound. Notice how H is located in more than one place.
Explanation:
Answer:
168°C is the melting point of your impure sample.
Explanation:
Melting point of pure camphor= T =179°C
Melting point of sample = 
= ?
Depression in freezing point = 
Depression in freezing point is also given by formula:
= The freezing point depression constant
m = molality of the sample = 0.275 mol/kg
i = van't Hoff factor
We have: = 40°C kg/mol
i = 1 ( non electrolyte)
168°C is the melting point of your impure sample.
