Answer:
Sunlight, Electric Arcs, And specialized lights
Explanation:
Answer:
The balanced equation would be
2Na(s) + 2H2O(l) ===> 2NaOH(aq) + H2(g)
where
s---solid
l--- liquid
aq--- aqueous
g---- gas
Are the states of each substance
Answer: The mass of
and
produced are 336.6 g and 183.6 g respectively.
Explanation:
The combustion reaction between propane and oxygen leads to formation of carbon dioxide and water.
Law of Conservation of mass states that the mass will remain constant for a balanced equation. This is carried out when the total number of atoms on reactant side is same as the total number of atoms on the product side. Thus the equation must be balanced.

a) 1 mol of propane produces = 3 moles of
Thus 2.55 mol of propane produces =
mass of 
b) 1 mol of propane produces = 4 moles of
Thus 2.55 mol of propane produces =
mass of
The mass of
and
produced are 336.6 g and 183.6 g respectively.
Answer:
frequency it the measure of the wave length. The measure of the peaks and troughs is how you measure the frequency. the distance between these is the wave length.
