Unit 2 part 6 - Period 3 acid base reactions

Question 1

Metal oxide?

Answer 1

Basic
- Na2O, MgO
= Giant ionic

Question 2

Non-metal oxide?

Answer 2

Acidic
- NO, NO2, CO2

Question 3

Mettaloid oxide?

Answer 3

Amphoteric ( can act as an acid or base)

Question 4

Basic oxides?

Answer 4

1. React w/water to form a base
2. Most acid/ base reactions happen in water
   Meaning Na2O has basic properties

Question 5

Acidic oxides?

Answer 5

1. Non-metal period three elements will react w/ water to form an acid (synthesis reaction)

Question 6

Why is rain acidic with a Ph of 5.6?

Answer 6

B/c CO2 is dissolved in water which produces carbonic acid

Question 7

Equation of carbonic acid?

Answer 7

CO2(g) + H2O(l) = H2CO3(aq)

Question 8

How is sulfurous acid formed?

Answer 8

Burning of fossil fuels in rain water

Question 9

Equation of sulfurous acid?

Answer 9

SO2(g) + H2O(l) = H2SO3(AQ)

Question 10

How is NO produced?

Answer 10

Internal combustion engines

Question 11

How is NO2 produced?

Answer 11

When NO reacts with the atmosphere with O2

Question 12

Equation of nitric acid?

Answer 12

NO2(g) + H2O(L) + O2(g) = HNO3(AQ)

Question 13

What does CO2, from the combustion of fossil fuels, dissolving in H2O inhibit?

Answer 13

Shell growth in marine animals
