Determine the gram formula mass of the compound KMnO4
If all of this O3 is converted to oxygen, O2, at the same temperature and pressure then what will be the volume of the oxygen formed?
What mass of hydrogen can be produced from 2.90 g of aluminum and 14.0 g of HCl in the above unbalanced reaction?
The drying oven, although thought to be set at 125°C, had an inside temperature of 84°C. How will this error affect the reported percent by mass of the limiting reactant in the salt mixture. too high, too low, or unaffected
Treatment of 1.385 g of an unknown metal M with an excess of aqueous HCl evolved a gas that was found to have a volume of 382.6 mL at 20.0 C and 755 mm Hg pressure.
Aliphatic esters have carbonyl stretches that absorb around 1750 - 1735 cm-1. Unstrained aliphatic ketones have carbonyl stretches that absorb around 1715 cm-1. Explain this observation.
Give the number of valence electrons of each element and draw the Lewis structure for each molecule.
Consider an ideal gas with a volume of V1. To what volume would you need to compress the gas to double its pressure?
What is the pH of the formic acid solution before you begin titrating? b. What is the pH after 50.0 mL of the potassium hydroxide solution has been added?
Fructose contains only C,H, and O. 17.1g of carbon dioxide gas and 7.26 g of water vapor were produced when 12.1 g of solid fructose were combusted with excess of oxygen gas.
