Balancing Chemical Equations Challenge

What analogy is used to describe balancing chemical equations?

• Chem Sudoku

• Chem Chess

• Chem Puzzle

• Chem Crossword

What cannot be changed while balancing chemical equations?

• Coefficients

• Neither coefficients nor subscripts

• Subscripts

• Both coefficients and subscripts

What is the purpose of balancing chemical equations?

• To ensure the number of atoms for each element is the same on both sides

• To change the properties of the compounds involved

• To make the equation look more complex

• To identify which elements are diatomic

What indicates the charge of an ion in a chemical equation?

• Coefficient

• Subscript

• Superscript

• None of the above

What is the first step in the trial and error method of balancing equations?

• Identifying reactants and products

• Adjusting coefficients

• Writing correct formulas

• Balancing diatomics

Which elements are saved for last when balancing equations?

• Compounds with the highest number of atoms

• Polyatomic ions

• Diatomics and lone elements

• Elements with the highest atomic number

Why is it important to write the correct formulas for reactants and products?

• To impress your chemistry teacher

• To ensure the equation is aesthetically pleasing

• To make balancing easier

• To avoid balancing the wrong equation

What technique is suggested if no whole number balances an equation?

• The divider technique

• The halver technique

• The multiplier technique

• The doubler technique

What should be treated as a single unit if they appear on both sides of an equation?

• All of the above

• Polyatomics

• Diatomics

• Lone elements

What should you do if balancing an equation doesn't work initially?

• Start over with a different method

• Double all coefficients and try again

• Give up on balancing the equation

• Change the subscripts
