Question

What is chemical equation? types of chemical equation? explain all with 1 example? I will mark u brainliest for good answer so please answer carefully

Answer 1

The way of representation a chemical reaction is called as chemical equation

(1):- Word chemical equation

ex-

Aqueous solution + zinc = aqueous

of copper sulfate. dust. Solution of

Zinc

+ Copper

(2):-Chemical equation

ex-

CuSO4+Zn ----------- ZnSO4+Cu

Answer 2

With many chemical equations you can break them down by the type of chemical equation. This helps you to predict how different chemicals will react when mixing them. The different types are below in bold with clear examples. Look at them and see what kind of patterns you can recognize. Use the periodic table or ion periodic table link if you need it.

SYNTHESIS (also known as combination):

Definition: Two or more chemicals on the reactants become a single chemical on the products.

Example 1: Na+(aq) + Cl–(aq) ——> NaCl(aq)

Example 2: Ca(s) + Br2(g) ——> CaBr2(s)

Example 3: 6 C(s) + 6 H2(g) + 3 O2(g) ——> C6H12O6(s)

Generic Example: A + B ——> AB

DECOMPOSITION:

Definition: One chemical on the reactants becoming two or more on the products.

Example 1: LiOH(aq) ——> Li+(aq) + OH–(aq)

Example 2: 2 K2O(s) ——> 4 K(s) + O2(g)

Example 3: 2 HCN(aq) ——> H2(g) + 2 C(s) + N2(g)

Generic Example: AB ——> A + B

SINGLE REPLACEMENT (also known as single displacement):

Definition: One set of chemical partners swap as they go from reactants to products.

Example 1: Na(s) + LiF(aq) ——> Li(s) + NaF(aq)

Example 2: 2 Fe(NO3)3(aq) + 3 Be(s) ——> 3 Be(NO3)2(s) + 2 Fe(s)

Example 3: 3 (NH4)2(CO3)(aq) + 2 PO43-(aq) ——> 2 (NH4)3(PO4)(aq) + 3 CO32-(aq)

Generic Example: AB + C ——> AC + B

DOUBLE REPLACEMENT (also known as double displacement):

Definition: Two sets of chemical partners swap as they go form reactants to products.

Example 1: KBr(aq) + LiCl(aq) ——> KCl(aq) + LiBr(aq)

Example 2: 3 MgS(aq) + 2 Cs3N(aq) ——> 3 Cs2S(aq) + Mg3N2(s)

Example 3: 2 Al(OH)3(aq) + 3 CaSO4(aq) ——> Al2(SO4)3(aq) + 3 Ca(OH)2(aq)

Generic Example: AB + CD ——> AD + CB

COMBUSTION:

Definition: A carbon compound and oxygen combined to become CO2 and H2O

Example 1: CH4(g) + 2 O2(g) ——> CO2(g) + 2 H2O(g)

Example 2: C6H12O6(s) + 6 O2(g) ——> 6 CO2(g) + 6 H2O(g)

Example 3: CH3COOH(aq) + 4 O2(g) ——> 2 CO2(g) + 2 H2O(g)

Generic Example: carbon compound + O2(g) ——> CO2(g) + H2O(g)
