Movement of Ocean water Choose ALL that apply Lesson 2.08 Question 4 options: This water sinks and moves toward the equator where it replaces less dense, warm water. Differences in the density of seawater cause it to move. Surface water at the poles is dense because of low temperatures and high salinity. none of the choices

The answer is just took the test

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
