Physics- Reactions Of Acids With Metal Oxidesa And Metal Hydroxides

Question 1

Metal oxide is a

Answer 1

Base

Question 2

Metal oxide equation

Answer 2

Acid + metal oxide -> salt + water

Question 3

Acid rain

Answer 3

Formed when non-metals such as carbon and sulfur react with oxygen to from sulfur dioxide and carbon dioxide.
The oxides dissolve in rain water to form weak acids (carbonic acid and sulfurous acid).
Main source of carbon and sulfur in the atmosphere is the burning of fossil fuels.

Question 4

Effects of acid rain

Answer 4

Slowly corrodes buildings
Causes damage to historical landmarks and statues
Changes the pH of soil
Causes rivers and ground water to become acidic
Environment is changed

Question 5

Limestone is

Answer 5

Used in agriculture to make soil less acidic

CaCO3 + H2SO3 -> CaSO3 + H2O + CO2

Question 6

Metals react with water and from

Answer 6

Hydroxides (OH)

Bases

Question 7

Equation of metal hydroxide

Answer 7

Acid + metal hydroxide -> salt + water
