Answer:
Explanation:
You just have to see the REACTANTS and PRODUCTS and look how much molecules are there and accordingly put numbers.
Eg:4Fe+3O2--------->2Fe2O3
In order to become a scientific theory the three
categories that it must pass are the following:
1) Can the phenomena be recreated in a laboratory setting?
2) Can variables be changed, yet still result in like observations?
3) Is the phenomena truly natural or was it the result of a man-made force
enacting upon it?
<u>Answer:</u>
211.9 J
<u>Explanation:</u>
The molecules of water release heat during the transition of water vapor to liquid water, but the temperature of the water does not change with it.
The amount of heat released can be represented by the formula:
where 
= heat energy, 
= mass of water and 
= latent heat of evaporation.
The latent heat of evaporation for water is 
and the mass of the water is 
.
The amount of heat released in this process is:
211.9 J
Both have a continuous light spectra the fluorescent source makes a spectra with more intense bands of mercury

Mechanical energy=
Kinetic energy + potential energy
Hope this helped!
