Hi
I hope you can understand this...the Na ion is attached to the oxygen using ionic bonding. The \/ are meant to symbolize the hydrocarbon chain. The || is a double bond that bonds oxgen to carbon.
O
||
Na O/\/\/\/\/\/ + CaCl2 -> ? + NaCl
To give you some background, it has to do with a soap solution being added to CaCl2 to yield compounds, including soap scum.
I am not sure, but I interpreted the structural formula to be
CH3(CH2)9COONa. Using this plus CaCl2, I need to come up with a balanced chemical reaction.
Is my structural formula correct? Probably not, because I ended up with the reaction:
CH3(CH2)9COONa + CaCl2 -> CH3(CH2)9COOCa + NaCl and it wouldn't balance.
Please help! I'm not sure how to better explain the question. The answer sheet only gives room for two reactants and two products.
Thank you
The format came out wrong - the double bond of oxygen to carbon occurs at the first apex.
The board doesn't know how to handle spaces so it ignores all spaces past the first one.
Here is what you want.
(It appears you have drawn 11 C--whatever it is I'll just use n for the number of CH2 groups.
2CH3(CH2)nCOONa + CaCl2 ==>(CH3(CH2)nCOO)2Ca + 2NaCl
Based on the information provided, it seems like you are trying to determine the balanced chemical equation for the reaction between a soap solution (CH3(CH2)9COONa) and CaCl2.
To start, let's first interpret the structural formula you provided, CH3(CH2)9COONa. This represents a compound called sodium stearate, which is a soap formed by the reaction between stearic acid and sodium hydroxide. So, your interpretation of the structural formula as CH3(CH2)9COONa is correct.
Now, let's balance the chemical equation for the reaction:
CH3(CH2)9COONa + CaCl2 -> ? + NaCl
To balance the equation, we need to make sure there is an equal number of atoms on both sides. Let's break down the compounds:
CH3(CH2)9COONa: This compound contains 1 carbon (C), 2 hydrogens (H), 1 oxygen (O), 1 sodium (Na) atom.
CaCl2: This compound contains 1 calcium (Ca) and 2 chlorine (Cl) atoms.
To balance the equation, we need to ensure that the number of each type of atom is the same on both sides. Here's how we can balance it:
2 CH3(CH2)9COONa + CaCl2 -> (CH3(CH2)9COO)2Ca + 2 NaCl
In this balanced equation, we have multiplied the soap compound by 2 to match the number of chlorine atoms in CaCl2.
Please note that it is essential to consider the stoichiometry and the state of the reactants and products to write a complete and accurate balanced equation. The above equation assumes the reaction takes place in aqueous solution. If you have any additional details or specifications, please let me know, and I'll be happy to assist you further.
