pudding because the electrons are dispersed within the atom.
P.S
Happy to help you have an AWESOME!!! day ^-^

Answer:
0.00353J/g/°C
Explanation:
I will assume the temperature of the ice to be approximately 0°C.
Moreover, Heat of fusion of water is 6kJ
Amount of heat used to melt 5.3g of ice = 5.3 x 6 / 18
=1.767g°C
Therefore
1.767 = 25 x specific heat cap. x 200
Specific heat cap. = 1.767/(25x200)
= 0.00353J/g/°C
Answer:
2
Explanation:
The atom shown in the image has 2 core electrons.
Electrons are the negatively charged particles within an atom. Therefore the total number of electrons surrounding the nucleus in the given specie is 7.
So;
We have 2 core electrons
And 5 valence electrons
The core electrons are the inner orbital electrons.
The valence electrons are the outermost electrons.
