Answer:
Part A
i) A property of water that contributes to its movement through capillary tubes is adhesion, which is the capacity of water to stick to other surfaces
ii) Water has a polar molecular structure as such the hydrogen present in the water molecules form bonds with the oxygen present in the silicon oxide molecules from which the capillary tube is normally made
Part B.
i) From the given graph, the function appears to have a vertical asymptote at x = 0, therefore, the plant can grow infinitely tall
ii) The molecular structure of the vessel can be modified such that the walls incorporate more oxygen molecules per mole which will increase the number and the strength of the hydrogen bond between the water molecules and the walls of the plant vessel and therefore, increase the capillary action, the water height and the maximum height of the tree
Explanation:
To calculate the average atomic weight, each exact atomic weight is multiplied by its percent abundance, then add the results together and round off to an appropriate number of significant figures. So according to what’s given, the average atomic mass of elements M should be (23.9850 x 0.7899) + (24.9858 x 0.1000) + (25.9826 x 0.1101) = 24.30
Answer: They are around the nucleus.
Explanation: Protons and neutrons are in the nucleus. Electrons are in the electron cloud which is around the nucleus.
Mole fraction is expressed as the number of moles of solute over the total number of moles of solute and the number of moles of solvent. When expressed in molal, this is equal to number of moles of solute per liter solvent. If the mole fraction is 1.00, this means, all that is in the solution is solute. Hence the molal equivalent is 1.00 too
