The molecular formula shows the exact number of molecules. Therefor, the empirical formula is the simplest formula of the molecular formula
        
             
        
        
        
Those reactions in which Alkyl Halide reacts with the solvent without the involvement of any acid or base is called as 
Solvolysis. In given problem <em>tert</em>-Butyl Bromide is a tertiary Alkyl Halide and we know well that tertiary alkyl halides undergo 
SN¹ and 
E¹ elimination reaction due to the formation of 
stable tertiary carbocation. In given example after the formation of carbocation when Isopropyl act as 
nucleophile it will produce 
ether and when it acts as a 
base it will produce 
unsaturated compound. The reaction along with both products is shown below,
 
        
        
        
<u>Given:</u>
Mass = 68 kg
Power = 65 W
<u>To determine:</u>
Calories burned during an 8.0 hr sleep
<u>Explanation:</u>
Energy is expressed as:
Energy = Power * Time
Now, the unit of power = Watt (W) 
1 W = 1 J/s i.e. 65 W = 65 J/s
Time = 8 hrs = 8 * 3600 s = 28800 s
Energy = 65 J/s * 28800 s = 1872000 J
Convert Joules (J) to calories (cal)
1 cal = 4.184 J
The calculated energy = 187200 J * 1 cal/4.184 = 447418 cal
Ans: The man burns nearly 447.4 kcal during an 8 hr sleep
 
        
             
        
        
        
Answer:
Animals do not photosynthesize.
Explanation:
Plants use chloroplasts to capture sunlight to convert to energy in order to photosynthesize. Animals do not do this, therefore it is not needed.
