Event 1 is an example of a chemical reaction.
<u>Explanation:</u>
Whenever if two solutions are mixed, then if there is any color change, or evolution of any vapors, bubbles or gas formation or if there is any formation of a color or white precipitate confirms that the occurrence of a chemical reaction.
If nothing happens said above then it is said that there is no chemical reaction occurs.
Here in the event 1 a clear liquid in one beaker poured into clear liquid in beaker 2 then there is a formation of orange liquid, which means there is a formation of a new colored liquid confirms that the chemical reaction occurred.
A vacuum: the motor starts the fan that causes the vacuum to have suction and the motor is what moves the bristles
A blender: the motor is what makes the blade spin

The element sodium (Na) in the periodic table requires the least amount of energy to remove the most loosely held electron.
<h3>What is the trend of sodium?</h3>
The periodic table is the arrangement of the elements based on their physical and chemical properties.
The sodium element requires the minimum energy to eliminate the electron from its outer shell.
The sodium element has low nuclear energy and small size making the shielding effect to be negligible.
The loss of an electron from the outer shell results in the achievement of a stable configuration.
Thus, sodium requires the least energy.

Answer:
independant=variable that has changed
dependant=variable affected by the change
water=independant, because if you put too much water the dependant that depends on water could die or too little dependant can die (dependant=plants)
