A survey of more than 12,000 teens found that the more love teens felt from their parents, the less likely they were to act in unhealthy ways having early sex, smoking, abusing drugs, and displaying alcohol violence. What are the three possible ways to explain this discovery? b) What characteristics of the experiment make it possible to isolate cause and effect?

What is the question

False, as a substance changes from a solid to a liquid and from a liquid to a gas the molecules get farther apart from each other

Answer(false);

Reaction involved in present system is :   c12h22o11 + h2o → 2 c6h12o6the reaction system is obeying following rate law:   rate = k[c12h22o11]thus, it is a first order reaction.now, for 1st order reactionrate constant (k) =  given: initial conc. = 3.0 g, final conc. = 2.7 g, t = 2.5 h∴rate constant (k) =  ∴ k = 0.04215 h-1now, for 1st order reaction, half life = 0.693/k = 0.693/0.04215 = 16.4 hthus correct answer is option b
