Not just unbalanced but insane. There is no compound with the formula HCI. HCl, yes but not HCI.
This equation is Ca + H2CO3 => CaCO3 + H2.
k2o+ h2co3 --> h2o + k2co3
The name is potassium carbonate, but there's NO (balanced) equation for just one compound. An equation is about a reaction e.g. synthesis or decomposition of K2CO3. This should be clearly stated in a question. Please rephrase it.
3 H2CO3 + 2 Al(OH)3 --> Al2(CO3)3 + 6 H2O
H2CO3 = Carbonic acid It is made by dissolving Carbon dioxide into Water. H2O + CO2 ----> H2CO3
There are to possible reactions depending on the relative amounts of each substance. If there is an abundance of sodium hydroxide the balanced equation will be: 2NaOH + H2CO3 --> 2H2O + Na2CO3 If there is more carbonic acid: NaOH + H2CO3 --> H2O + NaHCO3
The chemical equation for Carbonic Acid is H2CO3.
hco3- + h+ <---> h2co3
CaCl2 + H2CO3 -> CaCO3 + 2HCI
Let's see.2NaOH + H2CO3 --> Na2CO3 + 2H2OSodium carbonate is the salt. Though carbonic acid is a weak acid and a one to one mole ratio may not achieve this ideal reaction.
H2CO3 is Carbonic Acid or HCO3- is Bicarbonate
MgCO3 and H2O It's not balanced though
