11.In chemistry, a retort stand, also called a clamp stand, a ring stand, or a support stand, is a piece of scientific equipment intended to support other pieces of equipment and glassware — for instance, burettes, test tubes and flasks..
12.Crucible tongs are scissor-like tools, but instead of having two blades, these tools are replaced with two pincers or pieces of metals that concave together, which allow the users to grasp a hot crucible, flasks, evaporating dishes, or even small beakers.
13.A test tube holder is used to hold test tubes. It is used for holding a test tube in place when the tube is hot or should not be touched. For example, a test tube holder can be used to hold a test tube while it is being heated.
14. Rubber Aspirator.It serves as a vacuum source for filling reagents through a pipette or pasteur pipette and also help control the flow of liquid from the dropping bottle. By using rubber bulb, the contact of the mouth to the chemicals can be avoided
15.A white coat, also known as a laboratory coat or lab coat, is a knee-length overcoat or smock worn by professionals in the medical field or by those involved in laboratory work. Doctors wear lab coats. The coat protects their street clothes and also serves as a simple uniform.

11. what the meaning crucible
Answer:

Answer:

12. Identify the different functional groups in organic chemistry
Answer:
In organic chemistry, the most common functional groups are carbonyls (C=O), alcohols (-OH), carboxylic acids (CO2H), esters (CO2R), and amines (NH2). It is important to be able to recognize the functional groups and the physical and chemical properties that they afford compounds.Functional groups are often used to “functionalize” a compound, affording it different physical and chemical properties than it would have in its original form. Functional groups will undergo the same type of reactions regardless of the compound of which they are a part; however, the presence of certain functional groups within close proximity can limit reactivity. Functional groups can be used to distinguish similar compounds from each other.functional group: A specific grouping of elements that is characteristic of a class of compounds, and determines some properties and reactions of that class. functionalization: Addition of specific functional groups to afford the compound new, desirable properties.The Role of Functional Groups In organic chemistry, a functional group is a specific group of atoms or bonds within a compound that is responsible for the characteristic chemical reactions of that compound. The same functional group will behave in a similar fashion, by undergoing similar reactions, regardless of the compound of which it is a part. Functional groups also play an important part in organic compound nomenclature; combining the names of the functional groups with the names of the parent alkanes provides a way to distinguish compounds. The atoms of a functional group are linked together and to the rest of the compound by covalent bonds. The first carbon atom that attaches to the functional group is referred to as the alpha carbon; the second, the beta carbon; the third, the gamma carbon, etc. Similarly, a functional group can be referred to as primary, secondary, or tertiary, depending on if it is attached to one, two, or three carbon atoms. Functional Groups and Reactivity Functional groups play a significant role in directing and controlling organic reactions. Alkyl chains are often nonreactive, and the direction of site-specific reactions is difficult; unsaturated alkyl chains with the presence of functional groups allow for higher reactivity and specificity. Often, compounds are functionalized with specific groups for a specific chemical reaction. Functionalization refers to the addition of functional groups to a compound by chemical synthesis. Through routine synthesis methods, any kind of organic compound can be attached to the surface. In materials science, functionalization is employed to achieve desired surface properties; functional groups can also be used to covalently link functional molecules to the surfaces of chemical devices. In organic chemistry, the most common functional groups are carbonyls (C=O), alcohols (-OH), carboxylic acids (CO2H), esters (CO2R), and amines (NH2). It is important to be able to recognize the functional groups and the physical and chemical properties that they afford compounds.

15. explain the importance of chemistry in understanding the food function and characteristics
Answer:
The importance of food chemistry lies in its ability to protect food from spoilage and decomposition while also extending its storability. Culinary preservation techniques include a variety of techniques like pickling and fermentation as well as irradiation and drying.
Food scientists work with the chemistry of food ingredients to improve the food's quality and long-term stability. They research the use of chemical flavors, thickening agents, stabilizers, and preservatives in food and use their findings to improve and develop new food products.

26. Put a little of the HCI and sodium carbonate solution in an evaporating dish. With the use of crucible tongs, hold the dish over a burner flame. Evaporate the solution. Then taste the residue when it is no longer hot. What is the taste?
Answer:Methods of acid-base titration based on a sample dissolution exceeding normal acid, followed by back titration with a standard base is characterised in this experiment. Using bromophenol blue as an indicator, hydrochloric acid solutions were standardised against pure sodium carbonate. Here, we will study the titration of HCl and sodium carbonate in detail.
Aim
Determination of the strength of the diluted hydrochloric acid solution by titrating it against the normal sodium carbonate solution (M/10).
Theory
The hydrochloric acid solution can be titrated using a methyl orange indicator against the sodium carbonate solution. If a slightly acidic solution is titrated with a weak base, the endpoint is slightly acidic. The solution is slightly basic if a weak acid is titrated with a strong base since the salt produced is to a certain degree hydrolyzed. The reaction of sodium carbonate with HCl is given below.
Na2CO3(aq) + 2HCl(aq) → 2NaCl(aq) + CO2(g) + H2O(l)
CO32-(aq) + 2H+(aq) → CO2(g) + H2O(l)
These are the hydrochloric acid and sodium carbonate equations.
In acid-base titrations, the amount of the acid becomes chemically equivalent to the amount of base present. The solution becomes neutral in the event of a strong acid and a strong base titration of the solution.
Materials Required
Burette
Pipette
Conical flask
Burette stand
Funnel
Stirrer
White glazed tile
Measuring flask
