Cesium is one of the most reactive alkali metals. When it comes into contact with water, it reacts to form cesium hydroxide and hydrogen gas. The gas forms a bubble around the solid, which brings the cesium to the surface, and exposes it to more water. This then causes more cesium to react, releasing more energy that ignites the hydrogen gas, causing explosions on the water surface. a) How much heat would be liberated if 0.150 mol of solid cesium...
Solutions of sodium carbonate and silver nitrate react to form solid silver carbonate and a solution of sodium nitrate. A solution containing 4.50 g of sodium carbonate is mixed with one containing 3.50 g of silver nitrate. After the reaction is complete, the solutions are evaporated to dryness, leaving a mixture of salts. How many grams of each of the following compounds are present after the reaction is complete? sodium carbonate silver nitrate silver carbonate sodium nitrate

Draw the most stable form of cis-1-Bromo-4-methylcyclohexane and explain why it is the most stable form
A 2.1342.134 g sample of a solid mixture containing only potassium carbonate (MM=138.2058 g/molMM=138.2058 g/mol) and potassium bicarbonate (MM=100.1154 g/molMM=100.1154 g/mol) is dissolved in distilled water. A volume of 31.5231.52 mL of a 0.7440.744 M HCl standard solution is required to titrate the mixture to a bromocresol green end point. Calculate the weight percent of potassium carbonate and potassium bicarbonate in the mixture. K2CO3:_____ wt% KHCO3:_____ wt%
why does only covalent bond form between two or more nonmetals but not metals?...i am a eighth grader so i am not sure if i need to know them.
Explain why primary and secondary amines form hydrogen bonds but tertiary amines do not?
Solid sodium hydrogen carbonate, NaHCO3, decomposes on heating according to the equation: 2 NaHCO3(s) <--> Na2CO3(s) + H2O(g) + CO2(g) A sample of 1.00 x 102 grams of solid NaHCO3 was placed in a previously evacuated rigid 5.00-liter container and heated to 160 0C. Some of the original solid remained and the total pressure in the container was 7.76 atmospheres when equilibrium was reached. Calculate the number of moles of H2O(g) present at equilibrium. How many grams of the...
