Pick up a reaction slip from the
front. Work with one partner.
Copy the reaction onto paper.
• Label the type of reaction (synthesis,
decomposition, single replacement, or
double replacement)
• Use coefficients to balance the equation.
• Write the reaction as a word equation.
• Fill in the parentheses with (s) or (aq) for
any parentheses that are empty.
• This is IDENTICAL to test part 2.
