2Mg+O₂⇒2MgO
It can be a combustion reaction, or it can be a combination reaction
Answer:
The emission spectrum is formed when the electrons of a particular atom absorb energy and are excited (in this case by heating), reaching higher energy levels.
You can see it for example with an experiment where we light alcohol mixed with banana chips (it has potassium). The burning alcohol emits heat that makes potassium atoms excite and these in turn emit something red, orange light. If we add for example boric acid you see a green light.
Explanation:
For this problem, you first find the net resistance of the circuit which can be done by adding up the resistors since this circuit is a series. 10Ω+5Ω+6Ω=21Ω
Since we are given the current of 6A, we can use Ohm’s Law of V=IR.
V=6A*21Ω
V=126 volts
