What does 'aq' mean in a chemical reaction? Balance the equation with the half reaction method: Zn+No3^-=zn^2+N2. Consider the equation: A (g) + 3 B (g) to 4 C(g) If 3.0 moles of A is reacted with 6.0 mol...
1.. What is the definition of the "equilibrium constant"? Write the equilibrium constant expression for the following reaction: Pb^2+ (aq) + 2I^- (aq) <--> PbI2(s) 2. Consider the reaction studied i What does an equilibrium constant represent in a chemical equation?
Re: what is the sign of ΔH for the reaction CoCl4 2-(aq) + 6H2O(l) =Co(H2O)6 2+(aq) «Reply #1 on:November 19, 2011, 12:28:44 PM » what doe delta H say of the preferred direction of the reaction? what does the color change mean in terms of which side the equilib...
What does it mean when the calorimeter constant is negative? The initial temperature of a bomb calorimeter is 28.50 C. When a chemist carries out a reaction in this calorimeter, its temperature decreases to 27.45 C. If the calorimeter has a mass of 1.400 kg and specific heat of 3.52 J/(...
Interestingly, we also noticed from Table 1 that the smallest mismatch at interface does not naturally relate to the interface with the biggest work of separation (the strongest chemical bound), e.g., the result of the model b2. In contrast, model b1 has the largest Wsep while the ...

Although you are right that copper is multivalent and is capable of forming certain compounds wherein the copper is at an oxidation state of +1, that does not mean that when you treat copper with silver nitrate that it can/will combine with the nitrate and maintain the +1 state. And in...
By nucleation of holes, we mean the quasi-reversible detachment of an initial number of flat monomers from a flat cluster and their random intercalation with the water molecules on top of the BLM. In other words, a hole is just a flat monomer that, upon detachment from a flat cluster, ...
Since a nucleophile is a species that is donating a pair of electrons, it’s reasonable to expect that its ability to donate electrons will increase as it becomes more electron rich, and decrease as it becomes more electron poor, right? So as electron density increases, so does nucleophilicity...
What does a triangle mean in a chemical equation? Which is an example of a chemical reaction? What does a chemical reaction do? What can form as a result of a chemical reaction? What do chemical reactions produce? How do you balance chemical equations? What does 'aq' mean in a chemical...
