Naming
The chemical name for AlN
Aluminum nitride
The chemical formula for nitrogen gas
N2
2HgO→ 2Hg+O2 is this type of reaction
decomposition
_N2+_H2→ _NH3 is this type of reaction and is balanced as
Synthesis N2+3H2→ 2NH3
All of the elements on the grey staircase on the periodic table are this.
metalloids
The chemical name for SO2
sulfur dioxide
The chemical formula for diphosphorus trifluoride
P2F3
Sulfur burns in oxygen to produce sulfur dioxide is this type of reaction, and is written as this chemical equation.
synthesis, S + O2 → SO2
_SeCl6+_O2→ _SeO2+_Cl2 is this type of reaction and is balanced as
Single Displacement SeCl6+O2→ SeO2+3Cl2
This is produced in combustion, but is not a chemical.
energy
The chemical name for AgNO3
sodium nitrate
The chemical formula for calcium bromide
CaBr2
Be + Na2O → (product) is this kind of chemical reaction, and has this product
single displacement, Be3N2
_Al+_HgCl2→ _AlCl3+_Hg is this type of reaction and balanced as
Single displacement 2Al+3HgCl2→ 2AlCl3+3Hg
All of the signs of a chemical change are
colour change (unexpected)
odor change (unexpected)
precipitate
bubbles without heat
light produced
temperature change (unexpected)
sound produced
The chemical name for NiO
nickle (II) oxide
The chemical formula for potassium sulfate
K2SO4
CH4+O2→ C+H2O is this kind of reaction, and the first product is also referred to as
incomplete combustion, soot
_NH4Cl3+_Pb(NO3)2→ _PbCl2+_NH4NO3 is this type of reaction and balanced as
double displacement 2NH4Cl3+_Pb(NO3)2→ _PbCl2+2NH4NO3
This limits combustion, making it incomplete
amount of oxygen
The chemical name for Mn(SO4)2
manganese (IV) sulfate
The chemical formula for iron (II) phosphate
Fe3(PO4)2
Solid silver sulfide and aqueous copper(II) chloride are mixed together to produce silver chloride precipitate and copper(II) sulfide precipitate. It is this type of reaction, and is written (balanced and with state symbols) as this.
double displacement, Ag2S(s)+CuCl2(aq)→ 2AgCl(s)+CuS(s)
_C3H8+_O2→ _CO2+_H2O is this type of reaction and balanced as
C3H8+5O2→ 3CO2+4H2O is this type of reaction and balanced as
The reason it is incorrect to write Ca2S2 but correct to write N2O2
because N2O2 is a molecular compound (don't reduce) and Ca2S2 is an ionic compound (reduce after criss cross)
