Well, in an atom, there are an equal number of protons and electrons so they cancel each other out.
Answer:
White being the color and coming in small grains.
Explanation:
Physical properties are something you can clearly see about the object.
It is a physical property because you aren't changing the actual thing, you are just changing its size. A chemical property is changing the arrangements of the atom to give you a totally new substance that cant be changed into its original form.<span />
Answer:
Silver
Explanation:
Given parameters:
Mass = 116g
Energy = 511J
Initial temperature = 21.6°C
Final temperature = 40.5°C
Unknown:
Specific heat capacity and the type of metal = ?
Solution:
To solve this problem, we need to find the specific heat capacity of the metal given,
H = m x c x Ф
H is the energy
m is the mass
c is the specific heat capacity
Ф is the change in temperature
511 = 116 x c x (40.5 - 21.6)
511 = 2192.4c
c = 0.233J/g°C
The specific heat capacity of silver is similar to this.
