Answer:
The removal of one chlorine atom and addition of one fluorine atom.
Explanation:
When GeCl4 is transformed into GeCl3F by a substitution process, the main change that is occur in GeCl4 is the removal of one chlorine atom and addition of one fluorine atom. This process is known as substitution process in which two molecules exchange their atoms with each other when they comes in physically contact with each other.
Carbon is located in the fourth group, second period. It is also in the nonmetal section of the table as well
2.83 days into hours = 2.83 x 24 = 67.92 hours
67.92 hours into minute = 67.92 x 60 = 4075.2 minutes
4075.2 minutes into seconds = 4075.2 x 60 = 244,512 seconds.
