Answer:

                      An atom of ¹¹⁸Xe contains 64 neutrons.

Explanation:

Number of Protons:

            The number of protons present in any atom are equal to the atomic number of that particular atom. Hence, as the atomic number of Xenon is 54 therefore, it contains 54 protons.

Number Neutrons:

            The number of neutrons present in atom are calculated as,

                              # of Neutrons  =  Atomic Mass - # of protons

As given,

                               Atomic Mass  =  118

                               # of Protons  =  54

So,

                               # of Neutrons  =  118 - 54

                               # of Neutrons  =  64

In the winter, a heated home in the Northeast might be maintained at a temperature of 78°F. What is this temperature on the Cels
masya89 [10]

Answer:  25.6^0C,  298.6K

Explanation:

Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like ^0C and K  

These units of temperature are inter convertible.

We are given:

Temperature of the gas = 78^0F

Converting this unit of temperature into ^0C by using conversion factor:

^oC=\frac{5}{9}\times (^oF-32)

^0C=\frac{5}{9}\times (78^oF-32)

25.6^0C

Converting this unit of temperature into K by using conversion factor:

K=t^0C+273

K=25.6+273

298.6K

Thus the temperature on the Celsius and Kelvin scales are 25.6^0C  and 298.6K respectively.
