Answer:

<u>Option-(A): </u>3-methyl-butane-2-one.

Explanation:

  • <u>Analyses of the compound's properties:</u>

Upon the analyses of the compounds characteristics or properties we get to know that the compound is the one responsible for generating signals inside the IR spectrum as shown. Because, if we look into the bands around 2900-3000 cm-1 which will find some traces of the C-H bonds inside the given data. While, the C=O intense bands are found in a very low level inside the given band.

The right answer is the first molecule (3-methyl-butan-2-one).

There are many bands around 2900-3000 cm-1 proving the presence de C-H bound.

There an intense band in 1700 cm-1 proving the presence of C=O.

There's no band proving the presence of aromatic structure, C=C bond nor C-N bond.

A chemistry student must write down in her lab notebook the concentration of a solution of sodium hydroxide. The concentration o
taurus [48]

Answer:

The concentration the student should write down in her lab is 2.2 mol/L

Explanation:

Atomic mass of the elements are:

Na: 22.989 u

S: 32.065 u

O: 15.999 u

Molar mass of sodium thiosulfate, Na2S2O3 = (2*22.989 + 2*32.065 + 3*15.999) g/mol = 158.105 g/mol.

Mass of Na2S2O3 taken = (19.440 - 2.2) g = 17.240 g.

For mole(s) of Na2S2O3 = (mass taken)/(molar mass)

= (17.240 g)/(158.105 g/mol) = 0.1090 mole.

Volume of the solution = 50.29 mL = (50.29 mL)*(1 L)/(1000 mL)

= 0.05029 L.

To find the molar concentration of the sodium thiosulfate solution prepared we use the formula:

= (moles of sodium thiosulfate)/(volume of solution in L)

= (0.1090 mole)/(0.05029 L)

= 2.1674 mol/L

Identify which trends in the diagrams below describe atomic radius, ionization energy, electron affinity, and electronegativity.
mihalych1998 [28]

a)  figure describe ionization energy , electron affinity & electron negativity

b) figure describe Atomic Radius

c) does represent anything

Electronegativity : An atom attracted the bond pair of electrons in a covalent bond is called electronegativity of an element.       H-->Cl

Ionization energy : The amount of energy is required to remove of an electron from an isolated gas atom is called Ionization energy.   M + IP-----> M+ + e-

Electron affinity: The amount of enery is released when an electron added to an isolated atom is called electron affinity.

   X + e- ------> X- =- EA

Atomic radius ; The distance between the center of neuclies and outer most shell is called atomic radius.

Changes of state are a result of a change in the______of the matter.
jasenka [17]

Answer: -

Kinetic energy.

Explanation: -

Solids have the least kinetic energy and the highest intermolecular force of attraction among the three states of matter.

When heat energy is supplied to the solid, the kinetic energy of the solid particles increases. At some point, the kinetic energy becomes comparable to the intermolecular force of attraction. At that point solids change into liquids.

When further heat energy is given, at certain point the kinetic energy becomes far greater than the intermolecular forces of attraction. At that point it becomes gas.
