A 150.0 g sample of a Metal was heated to 95.0oC. When the hot metal was placed into 100.0 g of water in a calorimeter, the temperature of the water increased from 20.0oC to 35.0oC. The specific heat of water is 4.184 J/g • oC. (a) What is the specific heat of the metal? (b) What would the final temperature be if the mass of water was 150.0 g?

specific heat capacity of metal = 0.697J/g-°c

b) final temperature will be 30.71°C

Explanation:

Detailed explanation and calculation is shown in the image below

chemists can use the electron cloud model to assign electrons to different atomic orbitals. atomic orbitals also explain the patterns in the periodic table

explanation:

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.
