EQUATION WORKSHEET #1
A. BALANCING EQUATIONS FOR SYNTHESIS REACTIONS.
Synthesis or combination reaction involves the combination of two or more
substances to form a compound.
Balance the following equations by writing the simplest whole number coefficient in the
space provided.
1. ____ H2 (g) + ______ F2 (g) ----- > _____ HF(g)
2.
_____ Sb(s) + _____ Br2(l) -------- > ________ SbBr3(g)
3. ______ Ag + ______ O2 ---->______ Ag2O
4. ______ H2(g) + ______ Cl2(g) ---->______ HCl(g)
5. _____ Na(s) + _____ O2(g) ------ > ______ NaO(s)
Write in the formulae for the products in the following synthesis reactions and then
balance the equations.
- To predict the product, you must join the two reactants together.
- The formula of the product is determined by examining the combining capacities of
each reactant. Do not simply join the two together maintaining the same coefficient
of the reactants.
