In an experiment to find the thermal energy transfer of a material the following characteristics were found: Mass = 10 kg

Initial Temp = 20 C

Final Temp = 40 C

C = 1400 J/KgK

Calculate the thermal energy transfer for this experiment.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

the answer is true. hope it .
