At 20.°c, a 1.2-gram sample of mg ribbon reacts rapidly with 10.0 milliliters of 1.0 m hcl(aq). which change in conditions would have caused
the reaction to proceed more slowly?
(1) increasing the initial temperature to 25°c
(2) decreasing the concentration of hcl(aq) to 0.1 m
(3) using 1.2 g of powdered mg
(4) using 2.4 g of mg ribbon
