Click on the correct answer.
1
The reaction of magnesium with carbon dioxide is an example of
a combination reaction
a single replacement reaction
a redox reaction
a physical change
a combustion reaction
2
A substance may be
stable under one set of conditions and unstable under a different set of conditions
unstable under all conditions
stable under all conditions
3
Magnesium can react with
acid
carbon dioxide
sulfur
chlorine
oxygen
4
What happened when Jeremy put the burning splint into carbon dioxide?
It burned brighter
It exploded
It went out
5
Magnesium metal
can be lit with a flame
burns in air
burns in carbon dioxide gas
burns even at dry ice temperatures
burns with a very bright light
6
Which is true of magnesium when it burned in air?
the magnesium reacted to form products that did not contain magnesium atoms
the magnesium reacted to from products that contained magnesium atoms
the magnesium converted the air to carbon dioxide
the magnesium reacted with the oxygen in the air
the magnesium reacted with the nitrogen in the air
7
A "combustion" reaction
refers only to paper or wood burning
is an exothermic reaction
produces light
occurs with some metals
does not occur with metals
8
When magnesium combines with oxygen,
one magnesium atom combines with two oxygen atoms
one magneiusm atom combines with three oxygen atoms
two magnesium atoms combine with two oxygen atoms
two magnesium atoms combine with three oxygen atoms
one magnesium atoms combines with one oxygen atoms
9
When magnesium combines with nitrogen
the combination ratio is one to one
the combination ratio is one magnesium to two nitrogen
the combination ratio is two magnesium atoms to one nitrogen atom
the combination ratio is three magnesium atoms to two nitrogen atoms
magnesium does NOT combine with nitrogen
10
Most of the air is
oxygen
nitrogen
carbon dioxide
neither A, B, nor C
