3a. The table below shows the results of an experiment performed by reacting 6.0g of a metal M with 10.0cm3 of 0.50 mol/dm3 HCI. 5 10 15 20 25 30 40 Time (sec) Volume of H2 collected (cm) 60 100 150 30 50 65 75 83 89 94 100 101 101 i. ii. Plot a graph of the volume of hydrogen collected against the time taken. Calculate the rate of the reaction in cm/sec. State the time taken for reaction to reach completion. Iv. Why did the 5-second intervals changed after 30 seconds? iii. b. On the same axes as in 3a above, sketch and explain the curve that would be obtained at (i). a higher temperature (ii) a lower acid concentration

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
