Question 2. (14 mks) Copper(I) oxide catalyses the decomposition of hydrogen peroxide. 0.5 g of the oxide was added to a flask containing 100 cm3 of hydrogen peroxide solution. A gas was released. It was collected, and its volume noted every 10 seconds. This table shows the results: fumes 0 10 20 30 40 50 60 70 80 90 Volume/cm3 0 18 30 40 48 53 57 58 58 58 draw a diagram of suitable apparatus for this experiment​

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
