A one litre is full of brown bromine vapours. The intensity of brown colour of vapours will not decrease appreciably on adding to the flask some

When a gas jar containing colourless air is kept upside down over a gas jar full of brown-coloured bromine vapour, then after some time, the brown colour of bromine vapour spreads into the upper gas jar making both the gas jars appear brown in colour. Which of the following conclusion obtained from these observations is incorrect ?

A student placed a gas jar containing air in the upside down position over a gas jar full of red-brown bromine vapours. He observed that the red-brown colour spread upwards into the jar containing air. Based on this observation, the student concluded that it is only the bromine vapour which moves up and diffuses into air in the upper jar, the air from the upper jar does not move down by diffusion into the lower jar containing bromine vapours. Do you agree with this conclusion of the student ? Give reason for your answer.

58.Which one of the following statements is incorrect? 1) In equilibrium mixture of ice and water kept in perfectly insulated flask mass of ice and water does not change with time. 2) The intensity of red colour increases when oxalic acid is added to a solution containing iron (III) nitrate and potassium thiocyanate. 3) On addition of catalyst the equilibrium constant value is not affected. 4) Equilibrium constant for a reaction with negative Delta H value decrease as the temperature increases.

When a gas jar full of air is placed upside down on a gas jar full of bromine vapours, the red-brown vapours of bromine from the lower jar go upward into the jar containing air. In this experiment :

The break-down of glucose in a cell occurs in any of the following pathways : Three experiments (A, B, C) have been set up. In each experiment, a flask contains the organism in growth medium, glucose and a brown dye that changes its colour to yellow when the pH decreases. The mouth of the flask is attached to a test tube containing lime water (Calcium hydroxide , as shown in the figure) . In C, but not in A and B , air is removed from the flask before beginning the experiment. After a period of growth, the following observation were made : A : Lime water turns milky , the dye colour remains the same B : The dye colour changes , lime water does not turn milky C : Lime water turns milky , the dye colour remains the same (a) Question : Identify which of the reactions is the pathways depicted above is taking place in each experiment . Give reasons for your answer . (b) Question : Identify which of the reactions in the pathways depicted above is expected to occur in Red Blood Cells (RBCs)
