At 50 degrees Celsius and standard pressure inter-molecular forces of attraction are strongest in a sample of ethanoic acid.
Ethanoic acid has hydrogen atom bonded with a more electronegative atom; Oxygen. As a result, the molecule possesses strong intermolecular Hydrogen Bonds. Therefore; ethanoic acid, and all other carboxyllic acids have the tendency to form dimers.
Answer:
1 mole of calcium contains 6.023 
atoms.
Explanation:
1 mole is the amount of a substance that contains exactly 
constituent particles. 1 mole of a substance is always equal to the atomic mass of the element.
Hence, 1 mole of calcium will also have atoms.
Number of atoms in 1 mole calcium = 6.023 atom
Answer:
In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. More reactive metals have a greater tendency to lose electrons and form positive ions .
Explanation:
Yes ur well come
This all depends on lots of independent variables such as force used to roll the ball, wind resistance, etc. With no variables included, they would both move at the same velocity.
