Answer:
The pH of pure water is 7, the negative logarithm of 1 X 10-7. A neutral solution is one that is neither acidic nor basic. The hydrogen ion concentration equals the hydroxide ion concentration, and both equal 1 X 10-7 M. In a neutral solution, then, pH = pOH = 7.
Explanation:
Answer: The empirical formula is C₃H₃O.
Explanation: Assume we have 100 g of the compound. Then we have 65.65.5 g of C, 5.5 g of H, and 29.0 g of O.

Although ice is solid, as long as temperatures are above −20°C (−4°F) there is always a very thin layer of water on the surface that makes it slippery. Extra melted water from the rubbing between the blade and the ice vastly reduces the friction allowing the skater to glide across the ice with little effort.
Answer:
A. Li-O
Explanation:
The highest polarization will occur between the atoms of Li-O because they have the most electronegativity difference between them.
Polarization occurs when there is a separation of charge between the atoms of heteronuclear molecules.
The electronegativity gives the tendency for an atom to attract the electrons within the bond pair to itself.
To know the atom with most polarization, it has to be one with highest electronegativity difference. Li and O have the highest difference. Also, since the bond is between a metal and non-metal, it is obviously the most polarized.
