States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

It will be helpful to remember two guidelines about
significant figures.
Part A
1. After multiplication or division, the
answer cannot have more significant
figures than any of the original
A bakery measured the mass of a whole cake as 0.870 kg. A customer bought one slice of the cake and measured the
mass of the slice as 0.1151 kg. What is the mass of the remaining cake, without the one slice?
numbers.
2. After addition or subtraction, the
answer cannot have more digits to the
right of the decimal point than any of
the original numbers.
After determining the appropriate number of
significant figures, round off your final answer.
Express your answer in kilograms using the appropriate number of significant figures.

1. If the first digit you drop is greater
than or equal to 5, add 1 to the last
digit you keep. You are rounding up.
2. If the first digit you drop is less than 5,
do nothing to the digits you keep. You
are rounding down.

Part B
An unknown object is placed on a balance, which then reads 6.118 g. Its volume is measured to be 3.04 cm³. Find the
density of this object by dividing mass by volume.
Express your answer in grams per cubic centimeter to the appropriate number of significant figures.
