What is the reaction of CaCO3 and HCl?
Calcium carbonate reacts with aqueous HCl to give CaCl2 and CO2 according to the reaction -CaCO3(s) + 2HCl(aq)→CaCl2(aq) + CO2(g) + H.
What is the balanced equation of CaCO3 HCl CaCl2 CO2 H2O?
What is the balanced equation for CaCO3 HCl CaCl2 CO2 H2O? CaCO3 + 2HCl -> CaCl2 + CO2 + H2O Therefore this is now a balanced equation.
What is the balanced equation of HCl and NaOH?
NaOH + HCl → NaCl + H2O 2.
What type of reaction is CaCO3 HCl CaCl2 h2co3?
Learn about double replacement reaction definition, or as also known as double displacement reaction.
What is a balanced chemical equation example?
A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side. In this chemical reaction, nitrogen (N2) reacts with hydrogen (H) to produce ammonia (NH3). The reactants are nitrogen and hydrogen, and the product is ammonia.
How do you write a balanced symbol equation?
A balanced symbol equation has the same number of atoms of each element on both sides of the arrow. To balance an equation, add numbers to the left of one or more formulae.
What is HCl in chemistry?
Hydrochloric acid, solution is a colorless watery liquid with a sharp, irritating odor. Consists of hydrogen chloride, a gas, dissolved in water.
What type of reaction is CaCO3 → CaO CO2?
Decomposition
(a) Decomposition: A substance breaks down to smaller species. [e.g. CaCO3(s) → CaO(s) + CO2(g) Decomposition of limestone to calcium oxide (quicklime) and carbon dioxide on heating.]
Which chemical equation is unbalanced?
An unbalanced chemical equation is called a skeletal equation. For example, Hydrogen reacts with oxygen to form water In the above chemical equation, there are an unequal number of oxygen atoms in reactants and products, so it is an unbalanced equation.
What are some examples of chemical equations?
A chemical equation is a method of expressing the reaction between various chemical elements. A very simple example is the reaction between hydrogen and oxygen to produce water: 2H2 + O2 = 2H2O.
What is a simple chemical equation?
Simply put, a chemical equation tells you what’s happening in a chemical reaction. Here’s what a chemical equation looks like: Fe + O2 → Fe2O3. On the left side of the equation are the reactants. These are the materials that you start with in a chemical reaction. On the right side of the equation are the products.
