I think the answer is a or c
Answer:
H-F bonds are the strongest.
As Fluorine is the most electronegative element.
A)
1 g/cm³ --------------- 0.001 kg/cm³
5.52 g/cm³------------ ?
5.52 x 0.001 / 1
= 0.00552 kg/cm³
b) 1 g/cm³ ----------- 62.428 lb/ft³
5.52 g/cm³ ------- ?
5.52 x 62.428 / 1
= 344.60 lb/ft³
hope this helps!
Answer: Force disadvantage and distance advantage
Explanation: When mechanical advantage is less than one the force of the strength decreases because input force is greater than output force.
The distance increases ie the object is moving over a long distance.
Example when fishing with a long fishing rod the force applied to move the fish from the water is greater than the weight of the fish itself. The advantage of using the long fishing pole is that the distance over which the fish travels is greatly increased.
Hope this helps. It took me about half an hour before I could get this answer from my various searches. The idea might not be clear but this was what I was able to understand.
The correct answer is option 3. The degree of polarity of a chemical bond in a molecule of a compound can be predicted by determining the difference in the electronegativities of the atoms in a molecule of the compound. Electronegativities of the atom tell how the electrons are distributed in the molecule.
