You can't usually just use a single spectrum line to confirm the identity of an element because there are cases that the emission line id not clearly defined. When the emission line is very weak compared to surrounding noise, in which case the more datapoints you have to build up confidence for the existence of a particular emission spectra, the better.
Cant really explain, for say, but its D.-ide

Answer:
Yes.
Explanation:
Yes, this difference of readings will definitely affect the results of the experiment as well as the E values because the readings taken by both students are different from one another. There is a fault in one of the thermometer because both shows different readings of temperature of the same solution. This will affect the overall experiment and due to this error, we are unable to tell that which one reading is correct so the answer is uncertain or unsure.
The Erlenmeyer Flask was <span>introduced in 1861 by German chemist </span>Emil Erlenmeyer and is shaped like a cone. This has a triangular shape and mouth wide for it to be easier to pour and store liquids. The Volumetric flask<span> is used for preparing liquids with volumes of high precision. It has a </span>pear-shaped body and a long neck with a circumferential fill line. The Filter Flask is also known as the <span>A Büchner </span><span>flask. It is like the Erlenmeyer but this one is thick-walled and has a special arm in the side. It is used for filtering liquid. </span>
Answer:
<h2>14.85 moles </h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>14.85 moles</h3>
Hope this helps you
