Answer:
See explanation
Explanation:
The structure of ethylene is shown in the image attached. The two carbon atoms have a double covalent bond between them.
The two carbon atoms are sp2 hybridized. The bond between them is a covalent bond, there is one pi bond and one sigma bond between the carbon atoms. Between carbon and hydrogen, there are covalent bonds also. The covalent bonds are sigma bonds.
The pi bonds between carbon atoms is weaker than the sigma bonds between the carbon atoms. This is because, the side-by-side overlap the p orbitals in a pi bond is less effective than the end-to-end overlap of a sigma bond.

Answer:
d
Explanation:
neutrons and protons have the mass nearly 1.67*10-24 g
but neutrons have no charge.. protons are positively charged
 
        
             
        
        
        
Answer:
16
Explanation:
Protons have a positive net charge,
Neutrons being neutral don't have a net charge.
Each proton is one extra net charge if you have 16 of them and the neutrons don't affect your net charge you will have 16.
 
        
             
        
        
        
Answer:
0.4 
Explanation:
Given data:
Number of moles of SrCl₂ consumed = ?
Mass of ZnCl₂ produced = 54 g
Solution:
Chemical equation:
ZnSO₄ + SrCl₂    →    SrSO₄ +  ZnCl₂
Number of moles of ZnCl₂:
Number of moles = mass/ molar mass
Number of moles = 54 g/136.3 g/mol
Number of moles = 0.4 mol
Now we will compare the moles of  ZnCl₂ with SrCl₂  from balance chemical equation.
                           ZnCl₂              :             SrCl₂ 
                               1                  :                1
                            0.4                 :              0.4
Thus when 54 g of  ZnCl₂ produced 0.4 moles of SrCl₂ react.
