Answer:
have the same number of protons
Explanation:
Atoms of the same element will always have the same number of protons.
Protons are the positively charged particles in an atom which are located in the nucleus.
- To recognize an atom, the number of protons is used.
- The number of protons is the atomic number.
- On the periodic table, atoms are arranged based on the number of protons.
The answer to your question is : no.of moles of Si = 43/atomic mass of Si = 43/28.1 = 1.53
according to reaction 3 moles of Si gives 1 mole of Si3N4
so 1.53 mole of Si will give 1.53/3 = 0.51 mole of Si3N4
molar mass of Si3N4 = 140.28 g/mole
it means that 1 mole of Si3N4 = 140.28 g
so 0.51 mole of Si3N4 = 0.51 X 140.28 = 71.543 g
Answer:
iron, graphite,NaCl solution etc are some examples of good conductor of electricity
When particles collide, they transfer fro their thermal energy.
Hope this helps.
