Explanation:
mg 2+ losses 2 electron due to the charge on it making it change from 12 to 10.and ne is also 10
 
        
             
        
        
        
Redshift is said to be experienced when the light or any other electromagnetic radiations from an object undergo an increase in the wavelength but it does not mean that the light literally becomes red.
Redshift occurs due to the expansion of space. It means the farther away the galaxy is from us, the more space it has expanded in the time.
Because as the light left the galaxy, more of the light has been stretched and so more redshifted the light is.
 
        
             
        
        
        
Answer:
B. HCN    
Explanation:
         PCN stands for Parent Country National. A PCN is an individual who is working in the country other than his or her native or origin country.
         HCN stands for Host Country National. A HCN is the employee of the organization who is a citizen of the country where the foreign subsidiary is been located.
        TCN stands for Third Country National. A TCN is an individual of other nation who is hired by a government who represents neither his host country or the  government.
         Hence in the context, a person who returns to his native country and works at an MNE which have its headquarter in the country where the individual studied is termed as a Host Country National or HCN.
Thus the correct option is (B).
 
        
             
        
        
        
Three double bonds and four single bonds, or 3(+)+4=7+3, are present in cumulene.
Sigma bond between the hydrogen and carbon on the end-side of the cumulene is visible. Carbon and hydrogen are linked by a total of four sigma bonds. Carbon is joined to carbon in the center by 3 sigma bonds and 3 pi bonds. Cumulene now has a total of 7 sigma bonds and 3 pi bonds. A cumulene is a molecule in organic chemistry that has three or more cumulative (consecutive) double bonds. sp2 hybrid orbital of C overlapping with 2p orbital of O and one bond make up the bond.
In the case of compounds with two bonds, one bond is a sigma bond and the other is a pi bond. A triple bond indicates that the chemicals.
