displacement reaction are…

Answer 2

A) FORMATION OF A PRECIPITATE
B) REACTIONS THAT PRODUCE A GAS
C) REACTIONS THAT PRODUCE WATER

Question 3

formation of a precipitate is between..

Answer 3

any solid that forms as a
result of 2 solutions reacting together

Solution– a homogenous mixture of 2 or more substances

Question 4

Reactions that produce a gas are…

Answer 4

Carbonic acid into water and carbon dioxide gas
H2CO3(aq) → CO2(g) + H2O(l)

Ammonium hydroxide into ammonia gas and water
NH4OH → NH3(g) + H2O(l)

Sulfurous acid into sulfur dioxide gas and water
H2SO3(aq) → SO2(g) + H2O(l)

Question 5

Neutralization reactions ( ones that produce water) are when

Answer 5

acid reacts with a base to produce a salt and water
( a salt is a neutral substance)

A base reacts with an acidic oxide to also produce a salt and water

An acid reacts with a basic oxide to also produce a salt and water
