If baking soda ( sodium hydrogen carbonate) is heated strongly , the following reaction occurs: 2NaHCO 3 (s) Na 2 CO 3 (s)+H 2 O(g)+CO 2 (g) Calculate the mass of sodium carbonate that will remain if a 1.48 g sample of sodium hydrogen carbonate is heated.

What volume would 2.25 moles of ne has occupy at stp?

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.

Astudent states that 9.0 g of baking soda will form an unsaturated solution in 100 g of water. what do you need to know to decide whether this statement is correct? a. the temperature of the water and the molar mass of baking soda b. the percent by volume of the solution and the solubility of baking soda c. the temperature of the water and the solubility of baking soda at that temperature
