) Some students investigated the effect of the different concentrations of sugar in four drinks, A, B, C and D, on the movement of water across a partially permeable membrane. The students: • made four bags from artificial partially permeable membrane • put equal volumes of 5% sugar solution in each bag • weighed each bag containing the sugar solution • placed one bag in each of the drinks, A, B, C and D • after 20 minutes removed the bags containing the sugar solution and weighed them again. (i) The bag in drink A got heavier after 20 minutes. Explain why. A contains 0.1% sugar solution.
B contains 4.2% sugar solution.
C contains 6.9% sugar solution.
D contains 10.6% sugar solution.

Concentration of sugar in the bag was higher than in the drink or higher concentration of water outside the bag or in the drink boiling tube so water moved in (to the tubing by osmosis.

Explanation:

Concentration of sugar in the bag was higher than in the drink or higher concentration of water outside the bag or in the drink boiling tube so water moved in (to the tubing by osmosis.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
