Question

True/False (1 pt each) 1)A chemical bond is classified as a covalent bond if it involves the transfer of electrons. 2) Water and oil do not mix because water molecules are nonpolar and molecules that compose oil are generally non-polar. 3)Gases and liquids are compressible, but solids are not. 4) One mole of F2 gas at STP would take up the same volume of one mole of Ar gas at STP. 5) Evaporation is decreased by increasing the intermolecular forces. 6) Increasing the temperature increases the vaporization rate of a liquid because the excess energy is used to break covalent bonds. 7) T The minor component in a solution is called the solvent. 8 Molarity is defined as the moles of solute per liter of solvent 9) A Bronsted-Lowry acid is a proton donor. 10) The products of a neutralization reaction are carbon dioxide and water.

Explanation / Answer

I am solving the first four problems as per Chegg guidelines, post multiple question to get the remaining answers

1) A chemical bond is classified as a covalent bond if it involves the transfer of electrons

Answer: False

Reason: A chemical bond will have sharing of electrons because of less electronegativity difference between the two element and not transfer of electrons

2) Water and oil do not mix

Answer: False

Reason: Water and oil do not mix because water tries to react with itself being a polar compound, oil being less denser than water floats on the top of water forming a layer

3) Gases and liquids are compressible, but solid not

Answer: True

Reason: Gases and liquid are compressible but solids are not because of very close packing in case of solids. Compressibility order will be

Gases > Liquid > Solid

4) One mole of F2 gas at STP would take the same volume as one mole of Ar gas at FTP

Answer: TRUE

Reason: Using the ideal gas equation

PV = nRT

Since the temperature and pressure are fixed values at STP, so the volume is directly proprotional to number of moles, if moles are same, then the volume occupied will be same
