The number of protons in the atom - ANSWER- The atomic number of an element indicates
which of the following?
Increase the average thermal energy by adding energy - ANSWER- How can you increase the
temperature of a substance?
Repulsion between protons - ANSWER- Within the nucleus the stronger nuclear force is more
powerful than the electric force of?
In both processes atoms are converted to smaller atoms - ANSWER- Which of the following
statements about nuclear fission and fusion is not true?
Protons and neutrons - ANSWER- What sub atomic particle's are affected by a strong force?
Raising the temperature - ANSWER- Which of the following would cause the pressure of a gas
filled container to increase?
It is composed of two or more substances that it retain their own chemical properties - ANSWER-
Which of the following explains why saltwater is considered a mixture?
The liquid particles have more kinetic energy - ANSWER- How to particles of a liquid to from
particles of a solid?
, Temperature does not change during the phase change - ANSWER- At its boiling point a
substance changes from liquid phase. What happens to the temperature of the substance during
this phase change?
The burning of wax forms new compounds while the melting wax does not - ANSWER- The
melting wax is a physical change get the burning of wax is a chemical change what is the difference
between the physical changes and chemical change of wax in a Burning candle?
Graduated cylinder, balance - ANSWER- A student has been assigned to measure the density
of a irregular shaped piece of metal. Which tools would be most appropriate to carry out this task?
Magnetism - ANSWER- What is the best methods a separate paper clips from a mixture of salt
and pennies?
By chemically combining - ANSWER- Magnesium metal is grayish-white in color and reacts
actively with water. Fluoride is a greenish-yellow gas at room temperature and is a member of the
Hollidge and family. These two elements react to produce magnesium fluoride, a chemical
commonly used to making windows and lenses. How do the elements magnesium and fluoride
produce the compound magnesium flouride?
The number of atoms in the water remains constant - ANSWER- When 1 g of water is
evaporated the volume of the water vapor increases but the mass remains constant. Why does the
mass of the water remain constant?
Compound - ANSWER- Which of the following is produced when two or more elements
combine in a chemical reaction?
