Explanation:
The different subatomic particles in an atom are the:
- Protons which are the positively charged particles.
- Electrons which are the negatively charged particles.
- Neutrons which do not carry any charges.
Protons and neutrons are located in the nucleus of an atom which is the tiny center of the atom.
Electrons orbits around the nucleus and fill the rest of the volume of atom.
On one end of the electromagnetic spectrum are radio waves, which have wavelengths billions of times longer than those of visible light. On the other end of the spectrum are gamma rays, with wavelengths billions of times smaller than those of visible light.
Answer:
Iron
Explanation:
Heat released by the metal sample will be equivalent to the heat absorbed by water.
But heat = mass × specific heat capacity × temperature change
Thus;
Heat released by the metal;
= 45.9 g × c ×(95.2 -24.5) , where c is the specific heat capacity of the metal
= 3245.13c joules
Heat absorbed by water;
= 120 g × 4.18 J/g°C × (24.5-21.6)
= 1454.64 joules
Therefore;
3245.13c joules = 1454.64 joules
c = 1454.64/3245.13
= 0.448 J/g°C
The specific heat capacity of the metal sample is 0.448 J/g°C. The metal use is most likely, Iron.
