Q

What is an acidic oxide

A

an oxide that when reacting with water, turns into an acid
ex. carbon dioxide it makes carbonic acid,
nitrogen oxides NO2+H2O - > HNO3 + HNO2
Sulfur oxides

Q

How does the metal activity series help reaction perdiction

A

One element can displace things that are below it but not above it
The farther apart the elements are the faster the reaction will take place. only for SD reactions

13
Q

What are some problems with the activity series

A

only works if the reaction is aqueous or room temp
also ex.
Aluminum should react with hydrogen in steam but aluminum oxide needs to be scubbed off first
Copper cant displace hydrogen from acids but it can react with nitric and sulfuric acid bc they are oxidization agents

15
Q

DD will only happen if one of the products is…(3)

A
  1. A precipitate (no reaction if both products are aq)
  2. One product is a gas
  3. on products is a molecular compound

16
Q

How do ionic comp dissolve vs molecular

A

ionic compounds actually dissolve - the ions break up
molecular compounds disperse due to the attraction in polar water molecules

17
Q

What is the complete ionic equation

A

Equation showing all the ions in the reaction. The precipitate is shown together. The state must be written
Ag+(aq ) + NO3-(aq ) + Na+(aq ) + Cl-(aq )
–> AgCl(s) + NO3-(aq ) + Na+(aq )

18
Q

What is a net ionic equation

A

based off of the complete ionic equation, it only shows the elements involved in the reaction. Not spectator ions
Ag+(aq ) + Cl-(aq ) - > AgCl(s)

19
Q

Which products can further decompose into a gas and water (3)

A

H2CO3(aq),H2SO3(aq ),NH4OH(aq )

20
Q

Acid + carbonate
H2SO4(aq ) + CaCO3(s)

A

carbon dioxide + water+ionic compound
-> H2CO3(aq ) + CaSO4(s)
2. H2CO3(aq ) - > H2O(l) + CO2(g)

21
Q

Difference between complete and incomplete combustion

A

Complete is when there is an abundance of oxygen-
Makes carbon dioxide + water
Incomplete is when there is not enough oxygen -
results in CO , not one single balanced equation

22
Q

What are the 3 Unregulated car emissions

A

Nitrogen gas - air is mostly N
CO2 - contributes to global warming
water vapour - product of complete combustion

23
Q

What are the 3 regulated car emissons

A

NO2, NO3 - contributes to acid rain, causes irritation
CO - poisonous gas
hydrocarbons - contributes to smog

24
Q

What is a catalyst

A

Something that speeds up the reaction but is not used up in the process

25
Q

NO2, NO3 converter calalysts
and type name

A

Reduction catalyst
platinum, rhodium
takes oxygen out of the gases
makes N2 and O2

26
Q

Hydrocarbon and CO converter calalysts name

A

Oxidization catalyst,
platinum and palladium
adds oxygen and makes it burn, turns it into CO2 and water

27
Q

ic vs ous ending in acids
ex. sulfuric vs sulfurous acid

A

ic means there are the higher amount of oxygen atoms
H2SO4 and H2SO3

28
Q

What are the 4 endings based off of the amt of oxygen in the polyatomic ions

A

hypo - ite
ite
ate
per - ate
