The chart shows the time, initial velocity, and final velocity of three riders. a 4-column table with 3 rows. the first row labeled rider has entries gabriella, franklin, kendall. the second row labeled time with entries 10 seconds, 8.5 seconds, 6 seconds. the third column labeled initial velocity has entries 55, 50, 53.2. the fourth column labeled final velocity has entries 32, 50, 67. which best describes the riders? gabriella is speeding up at the same rate that kendall is slowing down, and franklin is not accelerating. gabriella is slowing down at the same rate that kendall is speeding up, and franklin is not accelerating. gabriella and franklin are both slowing down, and kendall is accelerating. gabriella is slowing down, and kendall and franklin are accelerating.

Consider three unlabeled bottles, each contain small pieces of one of the following metals. - magnesium - sodium - silver the following reagents are used for identifying the metals. - pure water - a solution of 1.0 molar hcl - a solution of concentrated hno3 (a) which metal can be easily identified because it is much softer than the other two? describe a chemical test that distinguishes this metal from the other two, using only one of the reagents above. write a balanced chemical equation for the reaction that occurs. (b) one of the other two metals reacts readily with the hcl solution. identify the metal and write the balanced chemical equation for the reaction that occurs when this metal is added to the hcl solution. use the table of standard reduction potentials (attached) to account for the fact that this metal reacts with hcl while the other does not. (c) the one remaining metal reacts with the concentrated hno3 solution. write a balanced chemical equation for the reaction that occurs. (d) the solution obtained in (c) is diluted and a few drops of 1 m hcl is added. describe what would be observed. write a balanced chemical equation for the reaction that occurs.
