What happens to iron placed in a test tube with a stopper?
Iron and oxygen in a test tube alone will not react (observed by placing a piece of iron in a test tube with a stopper).Iron and water in a test tube alone will not react (observed by completely submerging a piece of iron in water in a test tube with a stopper).Iron, water and oxygen in a test tube will react (observed by placing a piece of iron in a test tube and submerging half of it with water). The following reaction will take place: iron + water + oxygen ----> hydrated iron(III) oxide. Hydrated iron(III) oxide is the chemical name for rust, which will appear as orange flaking on the piece of iron. To speed up this reaction you can use a bit of salt as a catalyst.
Water will move higher in a narrow glass tube than in a wide glass tube because of?
It is because of Capillary action, the adhesive forces for water are effective in narrow tube, in a wide tube the weight of water resists the upwards movement of water.
Why doesn't Superglue stick to the tube?
Because Superglue sets up when it reacts with water. It only needs a tiny amount - the water in the air, or on human skin is quite enough. The manufacturers make sure that when the glue is put into the tube both glue and tube are bone dry. aantoon
When you lower the tube does level of water inside the tube increases?
Yes it does.
How high is 2 mL of water in a test tube?
It depends on what size test tube you are using.
Why does a test tube of fresh water freeze quickly in iced salt water?
salt lowers the freezing point of the water
Alternate Wordings for 'Which freezes first cold water or hot water or salt water?
One alternate wording is At waters freezing temperaturethere are 3 test tubes, cold water is in test tube A, hot water is in test tube B, and salt water is in test tube C. Which test tube at (32 degrees) which will freeze the fastest? i hope i helped!
How do you get salt out of salt water by only using a camping stove handkercheif pan elastic bands kettle plastic tube cup and matches?
Wrap the handkerchief around the plastic tube and secure it with the elastic bands. Stick one end of the tube into the spout of the kettle. If it's not a snug fit use the edge of the handkerchief to pack the gap. If the tube is long enough, let some of it lay slack in the pan and place the other end of the tube over the cup. Fill the pan with cool water and also wet the handkerchief. If possible, let one edge to the handkerchief contact the cool water in the pan. Fill the kettle with salt water and place it on the stove. Use a match to light the stove and bring the salt water to a boil. Steam will travel through the tube and condense when it is cooled by the wet handkerchief and/or the cool water in the pan. The condensate will continue down the tube into the cup. Now try the same thing with beer instead of salt water. Yeeeeeeee Haw!
Suppose that an investigator fills a dialysis tube with water and ties the ends she then places the tube in a salt solutionwhat will happen to the weight of the tube after 30 minutes?
it will shrink i just did this in my bio class =]
How would you make salt in a laboratory?
take some alkali in a beaker and some acid in a test tube that is enough to neutralize the alkali. then pour the neutralized material in an evaporating basin. put the evaporating basin on a stove, when the water is evaporated salt will appear.
Which is an example of how the cell membrane of a tube worm maintained a stable environment?
Some examples of how the cell membrane of a tube worm maintains a stable environments are that: - It prevents minerals in the water from flowing into the cell. - It prevents salt from flowing in.
How many days does it take to make homade distilled water?
You can make distilled water in less then thirty minutes. Afix a cone to the top of a pan of bowling water to collect the steam. Attach to the cone a tube then pipe it to another pan. wrap the tube in something cold to convert the steam back to water. The water that condenses and runs out of the tube is distilled water. The more you do this the more you reduce the water till its just water. Salts and so on don't boil at the same point water does so the salt is left in the original pain. only elements with a boiling point lower then water travel with the water vapor to the next pan.
What type of solution is created if salt settles on the bottom of the test tube filled with water?
ur all gay
What are baffles in water tube boilers?
Baffles in water tube boilers are generally spiral twisted pieces of metal (though other methods have been used) inserted into the flue tube to cause turbulence, in addition to back pressure for better heat extraction. Typically, the design is to break the laminar flow in the exhaust gases and allow a better heat transfer through the tube. This will lower stack temperature and increase over all thermal efficiencies in water tube boilers.
What is feed stack monitoring?
It is a feature on a hopper that allows it to know if there are any paintballs in the feed stack (the tube that goes into the gun) and feeds them in automatically if there aren't.
How do you make a water column gauge?
