Two or more substances in the same place but not chemically combined are called this.

mixture 1 pt

The Earth’s atmosphere is composed of a bunch of different gasses and is an example of this.

mixture 2 pt

H 2 O is the formula for water and is an example of this.

compound 3 pt

Chemical formulas are used to represent this.

compound 4 pt

Pure substances are considered pure because they are made from only one type of …….

Particle (atom or molecule) 5 pt

The number of sulfur atoms in the formula H 2 SO 4.

1 1 pt

A molecule of silver bromate is composed of 3 oxygen atoms (O), 1 bromine atom (Br), and 1 silver atom (Ag). This is the chemical formula for silver bromate.

AgBrO 3 2 pt

Which model below shows a compound? A B C

A 3 pt

Why does model C below show an element? A B C

It’s made from only 1 type of atom. 4 pt

How many different molecules are present in A below? A B C

1 5 pt

Which of the following compounds is ionic? LiF or C 2 H 4

LiF 1 pt

This type of bond occurs when electrons are shared between atoms.

covalent 2 pt

When atoms gain or lose electrons and become charged particles, they are called this.

ion 3 pt

The joining of atoms to form new bonds is a result of this.

Chemical bonding 4 pt

When new substances form as a result of chemical bonding, most of their properties do this.

change 5 pt

Elements in the same group on the periodic table of elements have the same number of these.

Valence electrons 1 pt

Noble gasses don’t form bonds because of this.

They have full outer shells or 8 valence electrons and are stable. 2 pt

The number of valence electrons for an element can be found by using this on the periodic table of elements.

The group number. 3 pt

Why do elements in group 1 react so easily?

They only have 1 valence electron. 4 pt

Group 16 elements bond easily with this group.

Group 2 5 pt

Is the following equation balanced? SnO + 2 H 2 → Sn + 2 H 2 O

No 1 pt

What is/are the coefficient/s in the following equation. 2 C 4 H O 2 → 8 CO 2(g) + 10 H 2 O

2, 13, 8, 10 2 pt

What is/are the reactant/s in the following equation? NaCl + AgNO 3 → NaNO 3 + AgCl

NaCl + AgNO 3 3 pt

What is/are the product/s in the following equation? 2Mg + O 2 → 2MgO

2MgO 4 pt

The Law of Conservation of Matter is reflected in balanced equations as the law states this.

Matter cannot be created or destroyed. 5 pt
