Determine whether or not the following reaction is a precipitation reaction. 3H2(g)+N2(g)→2NH3(g) Precipitation reaction: Two different aqueous salt solutions are mixed to obtain a precipitate. The precipitate is a solid substance that does not dissolve in water (...
Calcium carbonate is not very soluble in water, but calcium chloride is, so you would probably start with solid calcium carbonate and HCl solution, and end with çslcoum and chloride ions in solution. You could call that a solution of calcium chloride, but you may also have bicarbonate ions...
Is this true or false and can you explain why? True or false? Electrolytic reactions and voltaic reactions are both spontaneous reactions. In determining the equilibrium constant for a reaction, reactants or products in solid or aqueous form are not included in the expressio...
Consider salt water (aqueous sodium chloride) being heated. (a) Write a chemical equation to illustrate the above. (b) Explain whether the above is endothermic or exothermic. Calculate the energy change (in kilojoules per mole) for the...
What is the value of K for this aqueous reaction at 298 K? A+B \rightleftharpoons C+D \ \ \Delta G^o =10.94 \ kJ/mol Consider the hypothetical thermochemical equation 3A + B 2C, for which H = 65.5 kJ/mol....
Metallic surfaces can be sprayed or dipped with aqueous dispersions of PTFE particles to form a permanent coating. Dispersions of PTFE can also be spun into fibres. It appears to me that if one wants to make progress in mathematics, one should study the masters and not the pupils. - Niels...
(e.g. HBr, especially concentrated aqueous HBr), or a nucleophile such as mercaptoacetic acid di-lithium salt, potassium hydroxide, potassium tert-butoxide, or sodium or potassium thiophenolate, or a reducing agent such as LiAlH4), at or above room temperature (e.g. at reflux) with or ...
Day 2- 63. Express the composition of each of the following compounds as the mass percents of its elements (just percent composition) a. Formaldehyde, CH2O b. Glucose, C6H12O6 c. acetic acid, HC2H3O2 64. Considering your answer to Exercise 63, which type of formula, empirical or molecular...
