100

Which of state of matter has particles with little to no energy?

solid

100

What is the difference between element and mixtures?

Elements are a type of element 

while a mixture will have a physical combination of two or more elements/compounds.

100

Write the chemical symbol for Chlorine

Cl

100

What is the MAIN difference between a physical change and a chemical change?

Physical change doesn't form new substances while a chemical change does.

100

What elements are in the following chemical formula: 

NaCl

sodium and chlorine

200

Identify one shape property for liquids

1. Takes the shape of a container they are placed in

2. Cannot be compressed

200
What is the difference between elements and compounds?

Elements only have one type of atom while compounds have two or more different atoms chemically bonded.

200

What group and period is Nitrogen in?

Group 15, period 2

200

Describe three evidence of physical change

Change in shape

expansion or contraction

change in state

mixing or dissolving

non-permanent colour change

200

Carbon dioxide has one carbon atom and two oxygen atoms. Write the chemical formula

CO2

300

What happens to metals when heat is added?

It expands

300

Name the three subatomic particles and identify their charge

Proton - positive, Neutron - neutral/zero, Electron - Negative

300

How many protons does potassium have?

(Hint = atomic number = no. of protons)

19

300

Name three pieces of evidence that a chemical change has occured. 

Permanent colour change

gas produced

precipitate (solid)

change in temperature

light or sound

new substance formed

300

What is the composition of sodium sulphate? 

Na2SO4

two sodiums, one sulphur, four oxygen atoms
400

What will happen to the size of a blown up balloon if its placed in the freezer and why?

It will shrink because the spaces between particles will contract when heat is removed.

400

What is the image demonstrating?

mixture of elements 

400

Name a group 1 element.

lithium, sodium, potassium, rubidium, cesium, and francium.

400

Is this a physical or chemical change? Why?

mixing sand and water. 

physical. mixing and reversable. 

400

Identify the reactants and products:

Carbonic acid (H2CO3) is an ingredient in soft drinks. When you open a can of soft drink, a decomposition reaction takes and produces water and carbon dioxide.

Reactants: Carbonic acid, Products: water and carbon dioxide

500

Define Kinetic Theory

It describes the movement of particles in each state of matter and what happens when heat is added or removed.

500

Draw a representation of a compound

Two different shapes/sizes used.

500

Outline the trend of the reactivity as you go down the periodic table

Reactivity increases
500

Is this scenario showing a physical or chemical change? Why?

Mixing baking soda and vinegar to produce carbon dioxide gas

chemical. gas produced.

500
Write a worded equation for the following scenario:


Magnesium sulfate and hydrogen gas are produced when magnesium metal is placed in a solution of sulfuric acid.

magnesium metal + sulfuric acid --> magnesium sulfate + hydrogen gas
