What is the compound name for S4O5

Tetrasulfur pentoxide

Tetrasulfur pentoxide

Explanation: S is sulfur on the periodic table and O is oxygen on the periodic table. We use those two elements as our root words.

Since both elements are non-metals we name them using prefixes. The prefix for 4 is tetra- and the prefix for 5 is penta-.

So now we have Tetra sulfur pentoxygen, the last step is to -ide the second element which is where we get the answer Tetrasulfur pentoxide.

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
