2. What is a florence flask used for in chemistry?
A Florence flask is a type of flask used as an item of laboratory glassware. It is used as a container to hold liquids. A Florence flask has a round body, a single long neck, and often a flat bottom. It is designed for uniform heating, boiling, distillation and ease of swirling; it is produced in a number of different glass thicknesses to stand different types of use. They are often made of borosilicate glass for heat and chemical resistance. Traditional Florence flasks typically do not have a ground glass joint on their rather longer necks, but typically have a slight lip or flange around the tip of the neck. A common volume for a Florence flask is 1 litre
3. functions of flask laboratory apparatus
He developed a flask that has a flat bottom with a tapered neck. The mouth, or opening, is used for pouring solutions and may be closed with a stopper in order to store samples. These flasksare useful for mixing solutions for chemical reactions, or can be used for drying and vacuuming chemical product to remove water.
4. line of Florence Cathedral
Answer:
The line of the Florence Cathedral, also known as the Basilica di Santa Maria del Fiore, is characterized by its distinctive dome designed by Filippo Brunelleschi. The cathedral, located in Florence, Italy, is one of the most famous examples of Gothic architecture in the world. The dome, which was completed in 1436, is an engineering marvel and a iconic symbol of the city. It is the largest brick dome ever constructed and has served as a model for numerous other domes, including the dome of St. Peter's Basilica in Rome.

11. 1. Each of these flasks is the same size and at the same temperature. Whichone contains the fewest molecules (atm = unit of pressure). Why?1 atm2 atm3 am4 atmFlask 1Flask 2Flask 3Flask 4
Answer:
FLASK 1
Explanation:
Because as said in the formula given (atm = unit of pressure) FLASK 1 has the lowest molecule as it only has 1 atom.
So the container that has the fewest molecules is FLASK 1

20. QUESTION 13 Maria wants to know the mass of her science laboratory module, what laboratory apparatus should she use? a. Thermometer b. Platform balance c. Graduated cylinder d. Flask
Answer:
B.
Explanation:
A platform balance, also known as a platform scale, is a type of weighing apparatus used to measure the weight or mass of an object. It consists of a flat platform or surface where the object is placed and a measuring device, typically a spring or a strain gauge, that measures the amount of force applied to the platform. The measuring device is connected to a display that shows the weight of the object.
Platform balances can come in various sizes, with larger ones often used in industries and smaller ones used in laboratories or homes. They can be manually operated or have digital displays, and some models can be connected to a computer or other device for data collection and analysis.
Platform balances are commonly used for a wide range of applications, including weighing materials for production, measuring ingredients in recipes, and weighing items for shipping or mailing. They are a reliable and accurate way to measure the weight or mass of an object, and they are an essential tool for many businesses, laboratories, and individuals.

Answer:
when it is necessary to know both precisely and accurately the volume of the solution that is being prepared.
Fill the flask with distilled water to about half. Swirl the flask to dissolve and mix the contents thoroughly. Top up the flask with distilled water to just below the ring mark. Top up the remaining volume, using a wash bottle or pipette, until the meniscus is exactly at the ring mark.
