A
Explain what a metal and a nonmetal will replace if they are in a single replacement reaction?
Metal will replace cation
nonmetal will replace anion
Al2S3 -->
Al2S3 --> 2Al (s) + 3S (s)
Magnesium Oxide
MgO (s)
"HNO3 -->" is a ____________ reaction
decomposition
What reaction do you use the activity series for?
single replacement
Na + PbCl4 --->
4Na + PbCl4 ---> Pb (s) + 4NaCl (aq)
Al + Br2-->
2Al + 3Br2--> 2AlBr3 (aq)
Iron (III) Chloride
FeCl3 (aq)
This type of reaction is a NR if there are two aqueous products....
double replacement
Balance H3PO4 + Mg(OH)2 --> Mg3(PO4)2 + HOH
2H3PO4 + 3Mg(OH)2 --> Mg3(PO4)2 + 6HOH
How do you write the products of a double replacement?
cation 1 with last anion and cation 2 with anion 1
Na2O + CO2-->
Na2O + CO2--> Na2CO3 (aq)
Water - Both states
H2O (L) and (g) in
What do the reactants look like in a combustion reaction? What do the products look like?
reactants: C#H# + O2
Products CO2 + H2O
Explain the no reactions for single and double replacement reactions.
Single replacement- when the free element is NOT higher than the one in the compound
Double replacement-when both products are aqueous
NaCl + KNO3 -->
NaCl + KNO3 --> NaNO3 (aq)+ KCl (aq) NO REACTION
Al(OH)3 -->
2Al(OH)3 --> Al2O3 (s)+ 3H2O (L)
Dihydrogen monosulfide
H2S (g)
Explain why "Na2O + H2O -->" is not a double replacement reaction... What type is it then?
-because if you complete a double replacement with those reactants you would get the same compounds.
-it is a synthesis reaction
What products are yielded of a decomposition of an oxoacid (H+1 as cation and * as anion)?
water and a nonmetal oxide
O2 + NaCl -->
O2 + 4NaCl --> 2Cl2 (g) + 2Na2O (s)
C21H44 + O2 -->
C21H44 + 32O2 --> 21CO2 (g) + 22H2O (g)
