Question
Choose the letter of the best match for the description. Letters may be used only once. ____ the movement of water across a semi-permeable membrane A. Acid _____ bond type when atoms share electrons equally B. Base _____ scale that describes ability of an atom to attract electrons C. Dipole-dipole _____ determines whether a reaction releases or absorbs energy D. Electronegativity ____ study of properties & changes in matter E. Electromagnetic ____ bond type when atoms share electrons unequally F. Osmosis ____ accepts a proton G. Chemistry ____ a type of attractive force H. Non-polar covalent ____ donates a proton I. Polar covalent J. enthalpy Fill in the blanks in the following table.Explanation / Answer
1) Answer: F
In osmosis process water moves across the semipermeable membranes.
2) Answer: H
In non-polar covalent bonds there is no net dipole moment and therefore, the electron pair is shared equally
3) Answer: D
Electronegativity is told about the ability of an atom to attract electrons
4) Answer: J
Enthalpy of the reaction tell about the energy is released or absorbed.
5) Answer: G
In chemistry, we deal with the properties and changes of matter. So, the answer is G.
6) Answer: I
In polar covalent, the electron pair attracted more towards the more electronegative atom. therefore, electron pair is not shared
equally.
7) Answer: A
The proton acceptor is an acid
8) Answer: E
Electromagnetic is a type of attractive force.
9) Answer: B
Protons donor is a base.
