Select ALL of the following that are decomposition reactions 2HI(g)--->H2(g)+I2(g)
Ni(OH)2(s)--->NiO(S)+H2O(I)
2Hi(g)--->H2(g)+i2(g)
FeO(s)+O2(g)--->Fe2O3(s)

To save time, you can approximate the initial mass of the solid to the nearest ±1 g. for example, if you are asked to add 14.3 g of copper, add between 13 g and 15 g. which of the following sets include two samples with an equal density? which all that apply below 15.4 g gold and 18.7 g silver 15.2 g copper and 50.0 g copper 20.2 g silver and 20.2 g copper 11.2 g gold and 14.9 g gold
