what is this? i cant find it in my book or online and yet its on my ICE chart and have to fill out.......
You need to explain your post better. I have no idea what you're talking about.
There is a symbol on my ICE chart that i cant figure out what it is and its the c with an = sign through it
€ this is the symbol and its in the part where the listed solutions are
HNO2(aq) € H3O+(aq) NO2–(aq)
I 0.045 0 0
C -0.0043 +0.0043 +0.0043
E 0.0407 0.0043 0.0043
i think i figured it out i think it was suposed to mean HNO2 --> H30 + NNO2
It's an arrow. Sometimes computers print weird symbols for some of the keys.
HNO2 ==> H^+ + NO2^-
It seems you are referring to an "ICE chart." An ICE chart is commonly used in chemistry to help determine the equilibrium concentrations of reactants and products in a system. Here's how you can start filling out an ICE chart:
1. Identify the chemical reaction: Determine the balanced chemical equation for the reaction.
2. Define the initial concentrations: Write down the initial concentrations of the reactants and products in the system. If no concentrations are given, you may assume they are all zero.
3. Set up the ICE chart: Draw a table with three columns: "Initial," "Change," and "Equilibrium." List the reactants and products in the first column.
4. Determine the changes: Determine the changes in concentration for each species during the reaction. These changes can be positive or negative based on the stoichiometry of the reaction.
5. Fill in the equilibrium concentrations: Calculate the equilibrium concentrations by adding or subtracting the changes from the initial concentrations. The equilibrium concentrations are the values you are trying to find.
Remember, an ICE chart is a tool to help solve for unknown concentrations at equilibrium based on the initial concentrations and the reaction stoichiometry. The values for the ICE chart should be given or can be determined through additional information, such as the solubility of compounds or the partial pressures in a gaseous equilibrium.
If you are having trouble finding the specific information you need to fill out your ICE chart, it may be helpful to consult your textbook for examples or explanations. If you cannot find the necessary information there, you could also try seeking assistance from a teacher, tutor, or online resources specifically dedicated to chemistry or equilibrium calculations.
