Functions of the following equipment's are-
1. ASPIRATOR is a suction machine .It is a medical device that is primarily used for removing obstructions such as mucus, saliva, blood, or secretions — from a person's airway.
2.Beakes are useful as a reaction container for holding liquid or solid samples. They are also used for catching liquids from titrations and filtrates from filtering operations.
3. pipettes are used in laboratory to measure out or transfer small quantities of liquid, in volumes of milliliters (mL), microliters (μL).
4. fire tongs are used for holding hot apparatus.
5. test tubes are used for holding solutions and carrying out the reactions.

Hey there!:
Mass = ?
Volume = 35.5 mL
density = 3.6 g/mL
By the definition of density :
D = m / V
3.6 = m / 35.5
m = 3.6 * 35.5
m = 127.8 g
hope this helps!
Answer:
Chemical reaction B, because the product is a compound
Explanation:
A synthesis or combination reaction is that reaction that involves combination of two or more reactants to form a single product. The two or more reactants are often elements that chemically combine to form a single compound.
In this question, two chemical reactions are involved in which chemical reaction A has 1 reactants and 3 products while chemical reaction B has 2 reactants and 1 product. Based on the explanation above, the reaction B correctly identifies the synthesis reaction because the single product is a compound.
The answer is B. two chlorine atoms.
The chemical formula of the compound is BaCl2~
