In this system, ___ energy from the cyclist is converted to a lot of ___ energy and a little bit of ___ energy. The energy is from the turning bicycle wheel spins the turbine which generates ___ energy. The fluorescent light bulb converts energy into two new forms : a lot of ___ energy and do very little ___ energy

It can be classified based on its

The correct answer to this question is 28 

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

It's b, limestone.i gotchu, b.
