From the unbalanced equations below, identify the one that does not represent a redox reaction. a. h2co3(aq) → co2(g) + h2o(l) b. c(s) + h2o(g) → co(g) + h2(g) c. s2o32- (aq) + i2(s) → s4o62+ (aq) + i-(aq) d. febr2(aq) + br2(l) → febr3(aq)

2pos suppose an object in free fall is dropped from a building. its starting velocity is 0 m/s. ignoring the effects of air resistance, what is the speed (in m/s) of the object after falling 3 seconds? give your answer as a positive decimal without units. answer here

All motion is caused by force? true or false

In the experiment you asked to react hydrochloric acid and with sodium hydroxide. when measuring the volume of the reactants, which instrument would give the greatest precision.
