(01.07 HC) An experiment was conducted to determine if the intermolecular forces in two liquids affects their boiling points. Each liquid was sprayed on a
paper towel. Each paper towel was wiped across a glass table to moisten the surface. The table shows a partial record of the experiment.
Experimental Record
Liquid intermolecular Forces
A relatively strong
B relatively weak
What information should be recorded in the last column of the table? (1 point)
Oa
Time taken by the liquids to start boiling
Oь
Time taken by the glass surface to dry
Ос
Volume of liquid required to moisten the paper towels
Od
Time taken by the paper towels to become completely moist

h let me think

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

c)red bank

explanation:

red bank is a borough in monmouth county, new jersey, incorporated in 1908 and located on the navesink river, the area's original transportation route to the ocean and other ports.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
