Answer:
Explanation:
sp² hybridization is found in those compounds having double bond . 
Out of the given compounds only C₂H₂Cl₂ has double bond so this compound contains carbon with sp² hybridization . 
Rest have sp³ hybridization because they are saturated compounds .
 
        
             
        
        
        
Answer:
The specific heat of sodium is 1,23J/g°C
Explanation:
Using the atomic weight of sodium (23g/mol) and the atomic weight definition, we have that each mole of the substance has 23 grams of sodium.
starting from this, we use the atomic weight of sodium to convert the units from J / mol ° C to J / g ° C
 
 
        
             
        
        
        
nuclear fusion
Stars produce their energy through nuclear fusion. For most stars, this process is dominated by a process called the "proton-proton chain," a sequence of events that transforms four hydrogen atoms into one helium atom.
