Metal hydroxides break down into ______ and ______.

When writing equations into Formative:

Place a "space" between coefficients and formulas, between "+" signs and formulas.

example: 2 H2 + O2

Place a "space" between formulas and states of matter and make sure states of matter are in parentheses.

example: O2 (g)

For the reaction "arrow", use "two dashed lines" and a "greater than" sign and make sure there is a space before and after the arrow.

example: O2 --> 2 H2O

Final equation: 2 H2 + O2 --> 2 H2O

OR 2 H2 + O2 --> 2 H2O

*** If you use these rules, then Formative will grade your work correctly and you will get all your points.

a) Write balanced chemical equations.

b) States of matter can be left off.

c) See above on how to properaly write equations into Formative.
