What is the percent composition of sulfur in SO2

Alicia created a physical model to show how one of the human body systems works. She first adds sand and pebbles to a glass of water. Then, she uses filters to separate the solids from the water.

A student reacted NiS2 (MM = 122.83 g/mol) with O2 (MM=32.00 g/mol) to make SO2 (MM=64.07 g/mol) according to this balanced equation 2NiS2+5O2=2NiO+4SO2 If the actual amount of SO2 made were (4.3090x10^2) g ehen the theoretical yield was (8.

The enthalpy of formation of water is - 285.8 kJ/mol. What can be inferred from this statement? The enthalpy of the products is equal to the enthalpy of the reactants. Heat is absorbed during the process. Heat is released during the process.

Sketch the structure of the nitrogen containing product that is formed when ethalymine reacts with water.
