Question 18

Why do atoms react to other atoms?

Answer 18

Atoms react with other atoms because they lose, gain and share electrons to complete their outer shells. Atoms can bond together by ionic bonds or covalent bonds.

Question 19

What are ionic bonds?

Answer 19

Ionic bonds happen between a metal and a non-metal. The metal becomes a positive ion and the non-metal becomes a negative ion and they attract by an electrostatic force. (Kinda like the positive and negative magnets)

Question 20

What are covalent bonds?

Answer 20

Covalent bonds happen between non-metals. They share their electrons to complete their outer shell. For example two hydrogen atoms attaching to eachother.

Question 21

What do acids produce?

Answer 21

Positive hydrogen ions in water

Question 22

What do alkalis produce?

Answer 22

Negative hydroxide ions in water

Question 23

What is an aqueous solution?

Answer 23

A solution that is dissolved in water

Question 24

What are the different ways to find the PH of an alkaline or an acid?

Answer 24

• Universal Indicator
• Cabbage solution
• Litnus strips

Question 25

What is an exothermic reaction?

Answer 25

An exothermic process releases heat, causing the temperature of the immediate surroundings to rise.

Question 26

What is an endothermic reaction?

Answer 26

An endothermic process absorbs heat and cools the surroundings.

Question 27

word equation for the neutralization of an acid plus a base

Answer 27

NaOH → H 2 O OH- + Na

Question 28

what are two compounds that can neutralize an acid

Answer 28

Metal oxides and alkalis are two types of base
