<span>An example of sublimation is when a dry ice changes to carbon dioxide when kept in an open container. Sublimation is a change from solid phase to gas phase without passing through the liquid state. In this example, it is clear that the dry ice is solid form and it evaporates as gas without passing through the liquid state.</span>

Answer:
0.062J
Explanation:
Given parameters:
Height of raising the spoon = 21cm
Mass of spoon = 30g
Unknown:
Gravitational potential energy = ?
Solution:
The gravitational potential energy of a body is the energy by virtue of the position of a such a body in space.
It is given as:
G. P. E = mgh
where m is the mass
g is the acceleration due to gravity
h is the height
Convert the parameters to appropriate units.
21cm to m gives 0.21m
30g to kg gives 0.03kg
G.P.E = 0.03 x 9.8 x 0.21 = 0.062J

Answer:
A. decomposition.
Explanation:
Recall the types of chemical reactions and how they are typically written.
Synthesis : A + B ==> AB
Decomposition : AB ==> A + B
Double Replacement : AB + CD ==> AC + BD
Single Replacement : AB + C ==> AC + B
Now although it may seem that the given equation doesnt follow any of these as it has more parts, it follows decomposition.
Decomposition is simply a single compound being broken up into two or more products. So it can be written as ABC ==> A + B + C as well therefore the answer is A
