Are chemical reactions useful?
yes some chemical reactions are harmful to us. as digestion of food, photosynthesis, decomposition of organic waste are some examples of the useful chemical reactions.
Which is NOT a sign that a double displacement reaction has occurred?
1) Formation of a precipitate 2) Usually there is a colour change. 3)Neutralization reactions (also a double displ. reaction) involving an acid and a base form water which is a clue.
Why are the acidic extracts and the basic extracts cooled before neutralization?

Is energy always involved in making or breaking chemical bonds?
no, some reactions are spontenous.
Explain why plants are able to continue the dark reactions when they are not able to use the light reactions?
Explain why plants are able to continue the dark reactions when they are not able to use the light reactions?
What is salt neutralization?
Salts are the products of reactions between acids an bases (neutralization reactions).
Is neutralization endothermic or exothermic?
Acid (and base) neutralization are exotherm reactions
What are neutralisation reactions?
Neutralization reactions are those that involve acids and bases. The products formed in a neutralization reaction is a salt and water.
What are reactions between an acid and a base called?
Such reactions are called neutralization reactions.
Neutralization reactions produce what?
Salt and water
What does a neutralization reactions from?
It forms salt and water
What do neutralization reactions always make?
Neutralization reactions look like: Acid + Base ----> salt + H20 For example: HCl + NaOH ----> NaCl + H20
What do Acids react with in neutralization reactions?
In a neutralization reaction, an acid will react with a base to form a salt and water.
Are salts made from bases?
Salts are the products of the reactions between acids and bases (neutralization reactions).
What type of reactions is an acid-base reactions?
Neutralization
What can bases react with?
Acids undergo neutralization reactions with bases.
Why is the heat of neutralization for HBr reacting with NaOH and HNO3 reacting with KOH solution be identical?
First, write the net-ionic reactions for both neutralization reactions. Notice anything? They have the same net-ionic reaction! So, their heats of neutralization will be the same.
