Given what we know about lab safety, we can confirm that when dealing with unstable and erratic equipment such as the stirring mechanism, in this case, the best course of action is to deactivate the equipment until further notice.
<h3>Why should we turn off the equipment?</h3>
- The erratic nature of the stirring mechanism is making the entire system unstable.
- When dealing with a hot plate, and heating substances, we need to maintain stability at all times.
- We do this to avoid spills that may cause burns or other unwanted damages.
- Therefore, until we know why the stirring was erratic, we must turn the mechanism off.
Therefore, we can confirm that when dealing with faulty or unstable lab equipment, we must deactivate the equipment immediately in order to preserve our lab safety.

Nitrogen <---- Itś at 73% of Earths atmosphere.
Sucrose is a non ionic compound. It does liberates ion when dissolved in water unlike NaCl or other salts which dissolve in water and produce respective cations and anions.
Thus if any amount of sucrose is dissolved in water, it will form non ionic aqueous solution (it will dissolve completely). Thus sucrose solution being non electrolytic will not conduct electricity in aqueous solution.
the bulb will not light up as sucrose will remain in molecular form only
Delivering electricity to homes through high voltage lines, reduces the power loss that is caused by Joule's heating.
We know that:
P=VI
Where, P is power, V is the voltage and I is the current.
So if we keep P constant and make then voltage up, I must goes down.
According to Joule's first law : Power of heating generated by a conductor is directly proportional to the product of its resistance and the square of the current.
Now using the equation:
Q=I²Rt
Where Q is the heat generated, I is the current , R is the resistance and t is the time.
So by reduced I, heat loss will be reduced.
