1. in part 1 synthesis reactions, the product of the first reaction is al(oh)3. the product of the second reaction is mg(oh)2. describe what you observed in each reaction. next, consider the general ab form of a synthesis reaction. if the first set of reactants is nh4oh and kal(so4)2 and the second set of reactants is mgso4 and nh4oh, is either reaction considered a synthesis reaction as labeled in the laboratory? why or why not? note: mg(oh)2 and al(oh)3 are both used commercially as antacids.

What happens to the atomic radius when an elctron is lost

Astudent made a graph plotting the progress of a reaction over time. the student forgot to label the y-axis of the graph. a graph is shown with two graph lines. one graph line starts at a higher position on the y axis and slopes downwards towards the right. the other graph line starts at a lower position on the y axis and slopes upwards towards the right. the two graph lines stop short of intersecting each other and continue as separate lines which gradually become straight and parallel to the x axis. a vertical line is shown at a point where the two graph lines finally became parallel to the x axis. this vertical line is labeled equilibrium. the title on the x axis is time and an arrow pointing towards the right is shown above time. the title on the y axis is left blank. what best explains the label that the student should use on the y-axis? amount, because as the amount of product decreases, the amount of reactant increases over time. reaction rate, because forward and backward reaction become equal at equilibrium. amount, because the amounts of reactants and products become constant after equilibrium is reached. reaction rate, as the rate of forward reaction increases and rate of backward reaction decreases over time.
