Resonance is an event where an external force or vibration moves another system to oscillate with higher amplitude at certain frequences or there is a transfer of energy between two or more different storage modes.
Answer: It depends on the element.
Explanation: Every element has a different amount of protons in its nucleus. It is the same as its atomic number on the periodic table. For example: Hydrogen has an atomic number of 1 because it has 1 proton in its nucleus, Helium has 2, Carbon has 6, Platnium has 78, and so on...
Answer:
6.3 moles
Explanation:
From the balanced equation of reaction:
2 moles of aluminium reacts with 3 moles of chlorine gas to form 2 moles of AlCl3.
Therefore, 1 mole of chlorine will require: 2 x 1/3 = 0.67 mole of aluminium.
Hence, 0.67 mole of aluminium will be needed for 1 mole of chlorine. If 7 moles of aluminium is present, then:
7 - 0.67 = 6.33 moles of aluminium will be left.
To the nearest 0.1, it means 6.3 moles of aluminium will be left.
Answer:
There is 1 Sodium in NaCl, but 2 Sodiums in the sulfide. I can’t write it properly. But the “2” should be a subscript.
