Find the Error
Cl + NaBr → Br +NaCl
Br and Cl are both diatomic (Cl2 and Br2).
Finish the single exchange reaction
K + NaCl →
K + NaCl → Na + KCl
Na + Cl --> NaCl is a classic example of this type of reaction.
What is a combination reaction?
soluble
A bond between 2 non-metals involving the sharing of electrons
MgSO4 + LiOH → MgLi2 + SO4(OH)2
Mg and Li are both cations, sulfate and hydroxide are both anions. Wrong partners are bonded.
finish the double exchange reaction
Pb(NO3)2 + KI →
Pb(NO3)2 + KI → KNO3 + PbI2
A reaction that breaks down reactants into simpler substances.
What is a decomposition reaction?
A compound of a phosphate and an alkaline earth metal will be _______. (sol/insol)
insoluble
what are the formulas and charges for
hydroxide, sulfate, nitrate, and ammonium
OH- , SO42- , NO3-, NH4+
lithium sulfide = Li2S
calcium phosphate = Ca3P2
iron (III) sulfate = FeSO4
calcium phosphide, not phosphate
Finish the double exchange reaction
MgSO4 + LiOH →
MgSO4 + LiOH → Li2SO4 + Mg(OH)2
H2O2 → H2 + O2
What is a decomposition reaction?
identify the precipitate (solid product)
CuSO4 + NaOH → Na2SO4 + Cu(OH)2
Cu(OH)2 - copper (II) hydroxide
what are the chemical formulas for ethane and heptane?
ethane: C2H6
heptane: C7H16
Cu(NO3)2 + Na2SO4 → Na2NO3 + CuSO4
NaNO3 - sodium and nitrate are 1:1 - the ratio of sodium in a compound changes
finish the double exchange reaction
FeCl3 + NaOH →
FeCl3 + NaOH → NaCl + Fe(OH)3
a combination reaction consisting of hydrocarbons and oxygen in the reactants.
What is a combustion reaction?
identify the precipitate
CdSO4 + K2S → K2SO4 + CdS
CdS - cadmium sulfide *
hydrogen hydroxide is more commonly known as what?
water, or H2O
Co(NO3)2 (aq) + NaOH (aq)→ NaNO3 (s) + Co(OH)2 (aq)
wrong precipitate - Co(OH)2 is solid not NaNO3
complete the reaction and identify states of matter
BaCl2 + Na2SO4 →
BaCl2 (aq) + Na2SO4 (aq) → NaCl (aq) + BaSO4 (s)
A reaction where 2 soluble ionic solutions mix to form an insoluble solid.
What is a precipitation reaction?
identify the states of matter for compounds in this reaction
Pb(NO3)2 + NaI → PbI2 + NaNO3
Pb(NO3)2 (aq) + NaI (aq) → PbI2 (s) + NaNO3 (aq)
