I guess you could call them that. In chemistry, we call them Metalloids though.

If a light bulb is missing or Broken in a parallel circuit,will the other bulb light
umka2103 [35]
Yes, if it’s a parallel circuit the wires are two different wires so it will light because that bulb isn’t connected to the one that went out

2. 2. Consider the following reaction occurring in a closed chemical system. Assume that this reaction is at equilibrium and tha
Alika [10]

1. This is a combustion reaction.<span>

<span>Combustion reactions can happen with the </span>presence of O</span>₂ <span>gas. O₂<span> reacts with another element or compound and </span></span>oxidize<span> it. Here ethanol reacts with O₂<span> and produces </span></span>CO₂ and H₂O as products.<span> <span>Combustion is also called as </span></span>burning. <span>

2. Reaction will shift to right. <span>

</span><span>If more CH</span>₃CH₂OH is added to the system, then the</span> amount of CH₃CH₂OH will increase.<span> <span>Then the equilibrium in the system </span></span>will be broken.<span> <span>To make the equilibrium again, the </span></span>added CH₃CH₂OH should be removed.<span> To do that system will consume more CH</span>₃CH₂<span>OH to make products which helps to decrease the amount of ethanol. Hence, the reaction will shift to right.<span>

3. The reaction will shift to right.</span><span>

</span><span>If the water is extracted from the system, the </span>amount of water will decrease. <span>That means the </span>amount of products decrease. Then the system will try to gain equilibrium by increasing the water. To increase water the forward reaction should be enhanced. <span>Hence, the</span> reaction will shift to right.<span>

4. The reaction will shift to right.

</span><span>This is an </span>exothermic reaction <span>since it </span>produces heat. If the produced heat is removed, then the system will be cold. To maintain the temperature, system has to increase the amount of heat produced. Then, the forward reaction should be enhanced. Hence, the reaction will shift to right.<span>

5. The Le Chatelier's principle.

</span>Le Chatelier's principle says if a condition changes in a system which was in an equilibrium state, the system will try to gain equilibrium by correcting the changed condition back to normal. Most of industries which make chemicals use this principle</span>
