10 Questions
What is the method of balancing chemical equations described in the passage, and what is its characteristic?
The method of balancing chemical equations is called the hit-and-trial method, and its characteristic is that it involves making trials to balance the equation by using the smallest whole number coefficient.
What is the importance of including physical states of reactants and products in a chemical equation?
Including physical states of reactants and products makes a chemical equation more informative.
What is the purpose of Step VI in the balancing process?
The purpose of Step VI is to check the correctness of the balanced equation by counting atoms of each element on both sides of the equation.
What is the significance of the number of atoms of hydrogen in the reactants and products in the equation?
The number of atoms of hydrogen in the reactants and products is significant because it is balanced, with 8 atoms of hydrogen in the reactants and 8 atoms of hydrogen in the products.
What is the role of coefficients in balancing chemical equations?
Coefficients are used to balance chemical equations by multiplying the formulas of reactants or products to ensure that the number of atoms of each element is equal on both sides of the equation.
What is the difference between the partly balanced equation and the fully balanced equation in the passage?
The partly balanced equation is 4 Fe + 4 H2O → Fe3O4 + 4 H2, whereas the fully balanced equation is 3 Fe + 4 H2O → Fe3O4 + 4 H2.
What is the purpose of breaking down the balancing process into steps?
The purpose of breaking down the balancing process into steps is to ensure that the equation is balanced systematically and accurately.
What is the significance of the equation 3 Fe + 4 H2O → Fe3O4 + 4 H2 in the passage?
This equation is the fully balanced equation, which indicates that the number of atoms of each element is equal on both sides of the equation.
What is the importance of ensuring that the number of atoms of each element is equal on both sides of the equation?
Ensuring that the number of atoms of each element is equal on both sides of the equation is essential to satisfy the law of conservation of mass.
What is the role of iron in the equation 3 Fe + 4 H2O → Fe3O4 + 4 H2?
Iron is one of the reactants and is also present in the product Fe3O4.
