How many carbon atoms will be in the longest chain of 3,3,4,4-tetramethylhexane?
how many sub-chains will there be in 3,3,4,4-tetramethylhexane?

6and 4 i just did it 

The molecular formula of 3,3,4,4-tetramethylhexane is c10h22, where c10 signifies the number of carbon atom which is 10. the side chains are located and designated with a number, so in this molecular formula it has 4 side chains or groups represented by 3,3,4,4. 

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

Deposition is the transition of matter going from gas to solid without passing through the liquid phase.a.) gas—-> solid
