mark as brainiest
Answer:
Surfactant. Surfactant, also called surface-active agent, substance such as a detergent that, when added to a liquid, reduces its surface tension, thereby increasing its spreading and wetting properties
Explanation:
Initial concentration of magnesium nitrate M1 = 2.13 M
Initial volume of magnesium nitrate, MgNO3 V1 = 1.24 L
Final concentration of MgNO3, M2 = 1.60 M
Let the final volume of MgNO3 upon dilution be V2
Formula to use:
M1*V1 = M2*V2
V2 = M1*V1/M2
= 2.13 M * 1.24 L/1.60 M = 1.65 L
Thus, the final volume of magnesium nitrate solution upon dilution is 1.65 L
Explanation:
TO calculate emperical formula , we need percentage composition of the elements and molecular mass of a specific compound which is already given in the question
then create a table with 1.name of element, 2.percentage given and its atomic mass , 3.no. of moles
( %given/at.mass of element) ... then take the least value in the no. of moles you have found now and divide with each no. of moles value .. to get a simple digit number.
You have got the empirical formula
D) The objects particles move closer together.
