<h3><em><u>Paper Chromatography Methodology</u></em><em><u> </u></em><em><u>:</u></em></h3>
<em><u>paper chromatography, in analytical chemistry, technique for separating dissolved chemical substances by taking advantage of their different rates of migration across sheets of paper</u></em><em><u>.</u></em><em><u>.</u></em><em><u>The method consists of applying the test solution or sample as a spot near one corner of a sheet of filter paper.</u></em>
The characteristic being calculated here is the mean or the average of the data set.
To check:
(20.73 + 20.76 + 20.68 + 20.75)/4 [we divide it by 4 because there are 4 numbers]
= 82.92 / 4
= 20.73
Answer:
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.
Explanation:
Answer:
Helium
Explanation:
Helium is most likely to undergo a chemical reaction because
- It has a complete electron shell, so it does not need any more electrons
- Its electrons are closest to the nucleus, so it is extremely difficult to remove them
Gloves is the tool component which will unlikely present a hazard in this scenario.
<h3>
What is Hazard?</h3>
This is referred to as potential source of harm when performing various types of activities.
Gloves will unlikely cause harm as it is used to prevent the risk of electric shock when handling electrical devices which is why it is the most appropriate choice.
