The product that you obtain if you evaporate the water from the NaoH layer prior to acidifying the layer is salt of <u> para - tery-butyphenol</u>
<u><em>Explanation</em></u>
- Para-tery-butyphenol can be isolate after extracting it into NaOH solution through carrying out
- heating and then cooling,
- then 3M of HCl is added to acidify.
- Then ice bath is done if needed
- finally the precipitate is filtered.
- Para tery butyphenol can be used for production of alkylphenolic.
Magnesium is divalent. This means that one magnesium atom needs to lose 2 electrons in order to become stable.
Chlorine, on the other hand, is monovalent. This means that one chlorine atom needs to gain one electron in order to become stable.
Based on this, one magnesium atom will combine with two chlorine atoms, where the magnesium loses two electrons, one for each chlorine.
The formula of the compound formed is: MgCl2
B) The carbon atoms in graphite are arranged in widely spaced layers
Explanation:
Graphite is different from other allotropes of carbon because the carbon atoms in graphite are arranged in widely spaced layers. Graphite and diamond are the two main allotropes of carbon that are closely related.
- Both allotropes forms under extreme temperature and pressure. In geology, they are categorized as derivatives of changed rocks.
- Graphite is different from carbon because its atoms are arranged in widely spaced layers.
- Diamond has a packed and cross-linked structure that makes it rigid and very hard.

Descriptive investigations are mainly questions to uncover information. it does not have an hypothesis. It is mainly gathering information, it is not repeatable as you are just asking questions
Answer: 
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Thus in the reactants, there are 2 atoms of hydrogen and 2 atoms of iodine .Thus there has to be 2 atoms of hydrogen and 2 atoms of iodine in the product as well. Thus a coefficient of 2 is placed in front of HI.
The balanced chemical reaction is:
