As the number of protons increases but the distance between the protons and electron REMAINS THE SAME...
Aloiza [94]

Answer:

The correct option is;

The electronegativity increases

Explanation:

The electronegativity is the measure of an atom's ability to attract a shared electron pair. The electronegativity of an atom is dependent on the atom's atomic number and the separation distance between the electrons in the valence shell and the positively charged nucleus such that an increase in the atomic number results in an increase in electronegativity and an increase in the distance between the valence electrons and the nucleus, leads to a decrease in electronegativity.

The net force on a vehicle that is accelerating at a rate of 1.2 m/s² is 1500 newtons. What is the mass
kotegsom [21]

Answer:

1250kg

Explanation:

Given parameters:

Acceleration  = 1.2m/s²

Force  = 1500N

Unknown:

Mass on the vehicle  = ?

Solution:

According to newton's second law of motion:

  Force  = mass x acceleration

Since mass is the unknown, insert the parameters and solve;

       1500  = mass x 1.2

        mass = \frac{1500}{1.2}   = 1250kg

What are the basic properties of the outer shell of an element?
crimeas [40]

The number of electrons in the outermost shell of an atom determines its physical and chemical properties. All elements are most stable with 8 electrons (an octet) in their outer shell.

A sample of substance X that has a mass of 326. 0 g releases 4325. 8 cal when it freezes at its freezing point. If substance X h
solmaris [256]

The molar heat of fusion of X has been 775.6 cal/mol. Thus, option C is correct.

The molar heat of fusion has been defined as the energy absorbed or released by a mole of substance in converting between solid and liquid state.

<h3>Computation for the molar heat of fusion</h3>

The given mass of substance X has been, 326 g.

The molar mass of substance X has been 58.45 g/mol.

The moles of sample have been given as:

\rm Moles=\dfrac{Mass}{Molar\;mass}\\\\ Moles\;X=\dfrac{326\;g}{58.45\;g/mol}\\\\ Moles\;X=5.58\;mol

Thus, the amount of heat absorbed by 5.58 mol of sample has been 4325.8 cal.

The amount of heat absorbed by a mole of sample has been:

\rm 5.58\;mol=4325.8\;cal\\\\1\;mol=\dfrac{4325.8\;cal}{5.58\mol} \\\\1\;mol=775.6\;cal/mol

The amount of heat absorbed by a mole of sample in meting has been the molar heat of fusion.

Thus, the molar heat of fusion of X has been 775.6 cal/mol. Thus, option C is correct.
