Net ionic equation with CaCl2 and Na2CO3?
I did a lab and the sheet has 3 problems: I need someone to look over two of them and explain the third one. Write a balanced equation for the reaction that took place: I got - CaCl2 + Na2CO3 ----> CaCO3 + 2NaCl What kind of reaction took place: Double Replacement? And now it wants a Net Ionic Equation? How would I write that?
What is the equation for coal combustion?
Coal is just a rock you dig up from the ground. To answer any question about a chemical equation, you have to know what coal is, chemically— this question is kind of like asking “what is dirt?” Well, what kind of dirt??Coal is mostly carbon, with some, well, dirt mixed in. Along with the carbon you’ll find various hydrocarbons (think oil, tar, natural gas, etc) as well as varying amounts of other stuff— including sulfur, which is one of the big problems with burning coal. “High grade” types of coal like anthracite are almost pure carbon, burn clean, and are expensive because a lot of the easy-to-get stuff has already been dug up and burned. Cheaper coal has more of other stuff in it.The carbon in coal burns according to a super simple equation, combining with oxygen gas (combustion!) to form carbon dioxide gas, below:C + O2 → CO2This is mostly what you get when you burn coal. BTW, this carbon dioxide released by burning coal (and other fossil fuels) is responsible for much of the man-made climate change we’re currently experiencing.But, if there’s not enough oxygen around to fully burn the coal, you can also get carbon monoxide, thusly:2 C + O2 → 2 COThe other hydrocarbons in coal burn similarly, to produce carbon dioxide (and, because there is now hydrogen in the mix), water vapor:CH4 + 2 O2 → CO2 + 2 H20Teh sulfur in coal also burns like dis, makes mostly sulfur dioxide, which is bad because when sulfur dioxide gas goes into the atmosphere and combines with water (in a cloud, for example) it forms sulfuric acid, which then comes back down as “acid rain” and kills entire lakes, crops, dissolves limestone statues, rusts your bicycle, etc.S + O2 → SO2
When will a double replacement equation result in no reaction?
The question wording is kind of throwing my head for a loop. Do you mean: when will AB + CD ≠ AD + CB ? First things first, you need to check what you are doing. When two compounds react and their products are both soluble (aq) then they would break apart in the water. If you have to write a net ionic equation for the reaction, you would end up crossing everything out because they are all just separate ions floating around. This is an example of when AB wouldn't react with CD. However, both of the reactants must be aqueous. Example AB(aq) + CD(aq) ----> AD(aq) + CB(s) ----either AD or CB can be a precipitate (doesn't need to be a solid). Side note, these are not reversible reactions (this is easily understood by picturing yourself taking out a few ions in the net ionic eq).Like most things in chemistry, the reaction has to be thermodynamically favorably in order to happen. Meaning, if this reaction happens, will energy be released? This doesn't mean that is always the answer though. No. Chemistry is too clever for an easy answer. Sometime a reaction can occur just because it would make things less orderly. Entropy is seen everyday. Why does water evaporate even though it has to absorb energy to do so? because of entropy. ΔSsys > 0. This is also true for a lot of solutes (Ammonium nitrate). Imagine that you own a professional sports team and another team preposes a trade. In order for you to accept the trade, it needs to be beneficial for your team and/or to your community. The same is true for a chemical reaction. Gibbs free energy equation is helpful for thermodynamics of a reaction: ΔG=ΔH−TΔS (dG is the change is free energy, dH is the change in enthalpy, T is temp, and dS is the change in entropy. Look for a negative dG for a spontaneous reaction)(Keq can also affect the dG, but that is going beyond the question at hand and can make the math more complicated)Anyways, hope this helps! steps: 1)check solubility rules 2)check thermodynamics if necessary
