Question 5 Multiple Choice Worth 4 points) (07.02 MC)
During an endothermic reaction, H for the reactants was -600 kJ/mol. Which of the following statements is correct about the H for the products and the
comparison of the energy in bonds?
O it is less than - 600 kJ/mol, and the amount of energy required to break bonds is greater than the amount of energy released in forming bonds.
O It is less than -600 kJ/mol, and the amount of energy required to break bonds is less than the amount of energy released in forming bonds.
O it is greater than -600 kJ/mol, and the amount of energy required to break bonds is greater than the amount of energy released in forming
bonds.
O It is greater than -600 kJ/mol, and the amount of energy required to break bonds is less than the amount of energy released in forming bonds.

the answer is minerals.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
