Answer:
               Cp  =  0.093 J.g⁻¹.°C⁻¹
Solution:

The equation used for this problem is as follow,

                                                  Q  =  m Cp ΔT   ----- (1)

Where;
            Q  =  Heat  =  300 J

            m  =  mass  =  267 g

            Cp  =  Specific Heat Capacity  =  ??

            ΔT  =  Change in Temperature  =  12 °C

Solving eq. 1 for Cp,

                                 Cp  =  Q / m ΔT


Putting values,
                                 Cp  =  300 J / (267 g × 12 °C)

                                 Cp  =  0.093 J.g⁻¹.°C⁻¹

The molar heat of fusion of platinum (Pt) is 4.700 kcal/mol. How much heat must be added to 85.5 g of
zvonat [6]

Answer:

2.07 Kcal heat must be added to completely melt the platinum.

Explanation:

Given data:

Molar heat of fusion =  4.700 Kcal / mol

Mass of platinum = 85.5 g

Heat of fusion = ?

Solution:

Formula:

ΔH = n × molar heat of fusion

n = number of moles

Now we will calculate the number of moles:

Number of moles = mass / molar mass

Number of moles = 85.5 g /195.08 g/mol

Number of moles = 0.44 mole

ΔH = n × molar heat of fusion

ΔH = 0.44 mol × 4.700 Kcal / mol

ΔH = 2.07 Kcal

An electron charge e mass m and a positron charge e mass m revolve around their common center of mass under the influence of the
Katen [24]

Answer: v = 2π2 Kme2 Z / nh

Explanation:

The formula for velocity of an electron in the nth orbit is given as,

v = 2π2 Kme2 Z / nh

v = velocity

K = 1/(4πε0)

m= mass of an electron

e = Charge on an electron

Z= atomic number

h= Planck’s constant

n is a positive integer.

Which of the following is false about a neutral atom of hydrogen?
Nesterboy [21]

Answer: Option (C) is the correct answer.

Explanation:

A neutral hydrogen atom is defined as the atom in which electrons are resent in their ground state only.

Basically in a neutral atom electrons are present in their parent shell.

For example, atomic number of hydrogen is 1 and electronic configuration of a neutral atom of hydrogen is 1s^{1}.

Hence, it means there is only one electron present in its valence shell. So, in order to attain stability it will readily react with another atom to gain or share an electron.

Thus, we can conclude that the statement it is less chemically reactive than an atom of aluminum (Al), is false.
