i will give 80 points and brainliest answer to the first one that answers

Respuesta :

Answer:

A. 1 AgNO3 + 1 KCl ⇒ 1 AgCl + 1 KNO3 double replacement

B. 1 H2O + 1 SO3 ⇒ 1 H2SO4 synthesis

C. 2 KI + 1 Cl2 ⇒ 2 KCl + 1 I2 single replacement

D. 2 NaHCO3 ⇒ 1 Na2CO3 + 1 H2O + 1 CO2 decomposition

E. 1 Zn + 2 HCl ⇒ 1 ZnCl2 + 1 H2 single replacement

F. 1 BaCl2 + 1 Na2SO4 ⇒ 1 BaSO4 + 2 NaCl double displacement

G. 1 C3H8 + 5 O2 ⇒ 3 CO2 + 4 H2O combustion

H. 2 Al + 3 CuCl2 ⇒ 2 AlCl3 + 3 Cu single displacement

Explanation:

Use algebra to make sure you have the same amount of each element on each side (Reactants and Products) and only change the coefficients of the compounds and elements!

double displacement: AB + CD ⇒ AD + CB

single replacement: AB + C ⇒ A + CB

decomposition: A ⇒ B + C

synthesis: A + B ⇒ C

combustion: any reaction that involve oxygen and don't follow any of the previous reactions

To balance a chemical reaction equation, the number of atoms of each element on both sides of the reaction equation must be the same.

A chemical reaction equation has a right hand side (reactants side) and a left hand side (products side). The reactants combine to give the products. The number of atoms of each element on the reactants side must be exactly the same as the number of atoms of the same element on the products side.

The balanced chemical reaction equation for each of the reactions is shown below;

  • AgNO3 + KCl ------>AgCl + KNO3  double replacement reaction
  • H2O + SO3 -------> H2SO4  synthesis reaction
  • 2KI + Cl2 ------> 2 KCl + I2  single replacement reaction
  • 2NaHCO3 ----> Na2CO3 + CO2 + H2O decomposition reaction
  • Zn + 2HCl -----> ZnCl2 + H2             single replacement reaction
  • BaCl2 + Na2SO4 ------> 2NaCl + BaSO4  double replacement reaction
  • C3H8 + 5O2 ------> 3CO2 + 4H2O Combustion reaction
  • 2Al + 3CuCl2 -----> 2AlCl3 + 3Cu   single replacement reaction

If there is no molar coefficient written in front of any of the species then the molar is 1.
