Write a balanced chemical equation for the reaction between silver nitrate and aluminum. What type of reaction is this?
The water temperature before the reaction was 34.5°C, and after the reaction it had risen to 52.0°C. How many moles of water were formed?
For 2,5-dimethylhexane, draw a Newman projection (looking down the C3-C4 bond) representing the most stable conformation, least conformation and a gauche conformer
a mixture of nitrogen and hydrogen reacts as fully as possible to form a 56 l mixture of ammonia and hydrogen at stp. when this mixture is compressed to 10.0 atm and chilled to 200.0 K, all of the ammonia is liquefied leaving 3.2 L of hydrogen sti..
At a certain temperature, the half life of SO2Cl2 is 7.5 x 10^2 min. Consider a sealed flask with 122.0 g of SO2Cl2. How long will it take to reduce the amount of SO2Cl2 in the sealed flask to 45.0g?
At high temperature, hydrogen and carbon dioxide will reversibly react to form carbon monoxide and water vapor. At 986 C there are 0.11mol of each product and 0.087mol of each reagent in a 1.00L flask. What is Kc under these conditions
