...Calcium Carbonate ===> Calcium Oxide(s) + Carbon Dioxide(g).
CaCO3(s) + heat ===>CaO(s) + CO2(g).
...Calcium Oxide(s) + Water(l) ===> Calcium Hydroxide(s)
CaO(s) + H2O(l) ===> Ca(OH)2(s).
...Calcium Hydroxide(aq) + Carbon Dioxide (g) ===>
Calcium Carbonate(s) + Water (l)
Ca(OH)2(aq) + CO2(g) ===> CaCO3(s) (suspension) + H2O(l)
These equations do not need balancing, they are already balanced.
The "acid rain" here is the one created by the reaction in the air of water and carbon dioxide. They form carbonic acid, which will eat away at limestone, which is calcium carbonate. This reaction, which is reversable, is responsible for many of the huge caves in the world. Here's the word equation for the reaction: Calcium carbonate + carbonic acid <=> calcium ions + carbonate ions Note that the carbonic acid is aqueousmeaning it is in water, and water is the "medium" in which all this takes place, even though it does not necessarily show up in the word equation.
Limestone is calcium carbonate - CaCO3 (a formula not an equation).
A balanced chemical equation.
If the number of atoms of each element is the same on both sides of the equation, then it is balanced.
This is not an equation at all. An example of a correct (and balanced) equation would be: 2H2 + O2 --> 2 H2O
this is called having a balanced equation .....if both sides are not balanced u must correct it by changing the number of moles
The balanced equation is: CH4 + 2 O2 → CO2 + 2 H2O
CaCO3 give rise to CaO +CO2
CaCO3(s) --> CaO(s) +CO2(g) enthalpy is +178 kJ molˉ¹
A balanced chemical equation has correct placed coefficients and a representative chemical equation need these coefficients.
CaCo3+O2 -----> CaO2 + CO2 ************************** 2nd Opinion: Close, but no cigar. What you want is CaCO3 -----> CaO + CO2
The balanced equation is 2HCl + K2O -> H2O + 2KCl.
Its NOT a balanced Equation ,but a FORMULA. Al2(SO4)3 NB A balanced equation is for two or more reacting substances and their respective products.
limestone + lemon lol
Balanced equation of nitric oxide is no3 2-
Proteins have a very complicate chemical formula but not a "balanced chemical equation".
what is the balanced equation for Rubidium metal reacting with halogen iodine
The balanced equation for the production of ammonia is the following: N2 + 3H2 ---> 2NH3
An equation is balanced if each atom on both sides are the same amount
