#Question#: Write balanced equations for the following chemical reactions: a) Combustion of glucose b) Reaction between xenon tetrafluoride and water c) Reaction between aluminum and iron(III) oxide d) Formation of ammonia gas from its elements e) Reaction between sodium chloride, sulfur dioxide, steam, and oxygen #Answer#: a) C6H12O6 + 6O2 -> 6CO2 + 6H2O b) XeF4 + 2H2O -> Xe + O2 + 4HF c) 2Al + Fe2O3 -> Al2O3 + 2Fe d) N2 + 3H2 -> 2NH3 e) 2NaCl + SO2 + H2O + O2 -> Na2SO4 + 2HCl

Step-by-step solution

Identify reactants and products

In the combustion of glucose, the glucose molecule reacts with oxygen gas to produce carbon dioxide and water. So the reactants are glucose (C6H12O6) and oxygen gas (O2), and the products are carbon dioxide (CO2) and water (H2O).

Write the unbalanced equation

The unbalanced equation for this reaction is: C6H12O6 + O2 -> CO2 + H2O

Balance the equation

Balance the equation by adjusting the coefficients: C6H12O6 + 6O2 -> 6CO2 + 6H2O This equation is now balanced. #b) Reaction between xenon tetrafluoride and water#

Identify reactants and products

In this reaction, xenon tetrafluoride (XeF4) reacts with water (H2O) to produce xenon (Xe), oxygen gas (O2), and hydrogen fluoride gas (HF).

Write the unbalanced equation

The unbalanced equation for this reaction is: XeF4 + H2O -> Xe + O2 + HF

Balance the equation

Balance the equation by adjusting the coefficients: XeF4 + 2H2O -> Xe + O2 + 4HF This equation is now balanced. #c) Reaction between aluminum and iron(III) oxide#

Identify reactants and products

In this reaction, aluminum (Al) reacts with iron(III) oxide (Fe2O3) to produce aluminum oxide (Al2O3) and iron (Fe).

Write the unbalanced equation

The unbalanced equation for this reaction is: Al + Fe2O3 -> Al2O3 + Fe

Balance the equation

Balance the equation by adjusting the coefficients: 2Al + Fe2O3 -> Al2O3 + 2Fe This equation is now balanced. #d) Formation of ammonia gas from its elements#

Identify reactants and products

In this reaction, nitrogen gas (N2) and hydrogen gas (H2) react to form ammonia (NH3).

Write the unbalanced equation

The unbalanced equation for this reaction is: N2 + H2 -> NH3

Balance the equation

Balance the equation by adjusting the coefficients: N2 + 3H2 -> 2NH3 This equation is now balanced. #e) Reaction between sodium chloride, sulfur dioxide gas, steam, and oxygen#

Identify reactants and products

In this reaction, sodium chloride (NaCl), sulfur dioxide gas (SO2), steam (H2O), and oxygen gas (O2) react to form sodium sulfate (Na2SO4) and hydrogen chloride gas (HCl).

Write the unbalanced equation

The unbalanced equation for this reaction is: NaCl + SO2 + H2O + O2 -> Na2SO4 + HCl

Balance the equation

Balance the equation by adjusting the coefficients: 2NaCl + SO2 + H2O + O2 -> Na2SO4 + 2HCl This equation is now balanced.
