8. what are the laboratory apparatus?
Answer:
Laboratory apparatus are the tools required to complete lab work, including test tubes, pipettes, beakers, and graduated cylinders.
Answer:
beaker
Used to hold and heat liquids. Multipurpose and essential in the lab.
brushes
Used to easily clean the inside of a test tubes and other glassware.
Buchner funnel
Used with vacuum flask for performing vacuum filtration.
Bunsen burner
Used for heating and exposing items to flame.
burette
Used in titrations to measure precisely how much liquid has been delivered.
burette clamp

micropipette
Used for accurately measuring and delivering very small volumes of liquid-usually 1 mL or less.
mortar and pestle
Used to crush solids into powders for experiments, usually to better dissolve the solids.
pipette with pump
Used for accurately measuring and delivering small volumes of liquid-usually 0.1-10 mL.
ring clamp
Attached to ring stand and with wire gauze used to hold beakers or flasks while they are heated by a gas burner.
ring stand
Used to hold items being heated. Clamps or rings can be used so that items may be placed above the lab table for heating by Bunsen burners or other items.

Used for storing, mixing, and heating small amounts of chemicals.
test tube holder
Used to hold test tubes while heating.
test tube rack
Used to hold test tubes while reactions happen in them or while they are not needed.

Used to take temperature of solids, liquids, and gases.
utility clamp
Used to attach test tubes and other glassware to ring stand.
vacuum filter flask
Used with vacuum line and Buchner funnel for vacuum filtration.
volumetric flask
Used to measure one specific volume in mixing accurate solutions.
wash bottle
Used to wash or rinse other containers
watch glass
Used to hold solids when being weighed or transported. They should never be heated. Can also be used to cover beakers or other containers.
weigh boat
Used for weighing solids on a balance.
wing top
For obtaining broad, fishtail flame that heats large area and smoothly bends glass.
wire gauze
Used with a ring clamp to support glassware over a Bunsen burner. Spreads flame out for more even heating.

12. What is the function and use of a Wire Gauze
Glasswares should never be heated so a wire gauze is placed under the glassware to distribute the heat. You may want to use a flat bottom glassware so that it could be placed above the wire gauze. Examples of this are Erlenmeyer`s Flasks.

15. What is the function of the wire gauze and the tripod stand
A tripod is used to support a flask, beaker, or a cylinder above the Bunsen burner or an Alcohol lamp so they could be heated. Wire gauzes are placed above a tripod so that the heat would be distributed along the bottom part of your flask/beaker/cylinder. Another function of WIre gauze is to protect glasswares since glasswares should not be heated directly.

18. The importance of the laboratory apparatus
The Importance of Laboratory Apparatus
Laboratory apparatus is important because, without them, working in a laboratory is impossible. Many laboratory apparatus are used to conduct experiments, quality controls, chemical reactions, proving theories, and checking various substances. In addition to these, the importance of laboratory apparatus lies in the uses of each apparatus or material. There are many laboratory apparatus used in a laboratory. They are specifically made to withstand and hold a variety of experiments and such.
Examples of Laboratory Apparatus and Their UsesHere are five examples of apparatuses used in a laboratory setting:
Safety goggles, gloves, and laboratory gowns - used to cover the different and sensitive parts of the body and prevent injuryRing stand - hold glassware and other equipment while workingBeaker, flasks, and test tubes - for containing, heating, and mixing liquidsTongs and clamps - used to hold containers and test tubesTest tube rack - for holding test tubes especially when they have contentsRead more information about laboratory apparatus here: https://brainly.ph/question/142735

What are all the laboratory apparatus and their uses?
Laboratory apparatus are the most common utensils and appliances that you need while performing hands-on activities in a laboratory.
The laboratory apparatus depends upon the type of laboratory you are in and the experiment you are going to perform.
For example, if you are in a chemistry laboratory, the common apparatus you need to use are:
Test tube holders, tongs - for holding test tubes and beakers that should not or cannot be touched.
Test tubes - for holding small samples or for containing small-scale reactions.
Test tube stands - for keeping a few test tubes upright
Droppers - for adding a very small amount of liquid, drop by drop
Burettes - for adding a precise volume of a liquid
Pipettes - to dispense small and precise amount of liquid samples
Bunsen burners, hot plates, hot water baths - heat sources
Beakers, Erlenmeyer flasks - to contain reactions or to hold liquid samples
Watch glasses - a cover for beakers; sometimes used as an evaporating dish
Funnels - for funneling or for filtering
Graduated cylinders - to measure an amount of liquid
Volumetric flasks - to make precise dilutions
Wash bottles - for dispensing small quantities of distilled water
Wire gauges, clay triangles - to support a container while it is heating
Clamp stands - to support a piece of equipment or a part of it that is otherwise unstable
Balances - to measure the mass of a reagent or product
Kipp's apparatus - to produce a reagent gas (e.g. H2S) in a controlled manner
Spectrophotometers - to measure the absorbance and transmittance of a liquid sample
Fume hoods - to ventilate harmful gases

25. What is the function and use of a Wire Gauze
Wire gauze can be used to support a container (such as a beaker or flask) during heating. When the Bunsen burner flame is beneath it, with a tripod, the wire gauze helps to spread the flame (and heat) out evenly over the container. It is frequently used in combination with an iron ring and ring stand with a Bunsen burner underneath it (see the Related Questions for more information about an iron ring, ring stand, and Bunsen burner & tripod). A clay triangle serves a similar purpose, except that a clay triangle is used for a crucible instead.Did we answer your question?

30. 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.
