False, because generally forensics collect the evidence to make sure the evidence doesn’t get damaged or tainted.... hope this helps
At summer season, snow will melt and will produce water using generators we can produce electric energy.
And in spring and winter can produce electric energy also using the wind
Answer:
The heat contained is 1236 Joules
Explanation:
As we know
T
Where
T is the change in temperature
m is the mass in grams
c is the specific heat of water (ice) = 2.06 joules/gram
Substituting the given values, we get -
Joules
Fluorine atoms = 1.517 x 10²³
<h3>Further explanation</h3>
The mole is the number of particles contained in a substance
1 mol = 6.02.10²³
Moles can also be determined from the amount of substance mass and its molar mass

Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements
