Explosive when mixed with combustion materials. Never use fabric
gloves to handle substance.
Harmful if inhaled or swallowed. Solution labelled if stronger then 2m
.it may cause your eyes and skin to irritate.
These substances are dangerous with material like sugar, wood, clothes
and etc. these solution ignite easily burn vigorously when dry. This
should not be made available in the lab with concentrated sulphur.
Harmful if swallowed. Irritant to eyes skin and respiratory system.
Irritant to eyes. Avoid raising and it also irritant to eyes. Keep it
away from water it could cause water to boil if because of the salt.
Contact with combustion material may cause fire.
Harmful if inhaled or swallowed. Danger of cumulative effects.
Don’t spill it on chemicals.
Important = If you spill any chemicals on your skin and eyes quickly
wash it for it for 10 min and if you can still feel it keep it like
that until you don’t feel anything. Then get it checked by doctor.
· Put potassium chloride salts in a test tube using a spatula.
· Add few drops of nitric acid using a pipette. If the salt fizzes
(gives gas off), record the result in the table below and add acid
drops 1 by 1 until it no longer fizzes.
· Add distilled water to 1cm depth. Mix well.
· Add silver nitrate using a clean pipette. Record the results.
· Put the same salt into another test tube.

- Investigating for Cations and Anions In this experiment I will investigate what cations and anions are present in various compounds. This will include carrying out a qualitative analysis, because I need to find out what type of cations and anions are there and not quantitative analysis, which includes finding out how much of each element there is. Safety Points: · Wear glasses · Wear gloves · Do not mix more than two solutions · Only mix the solutions listed by the teacher · Handle the chemicals with extreme care · Put the chemical solutions into a test-tube which is resting on a test-tube holder · Follow school lab safety procedures....

- Ultrasonic sound- The PING))) ultrasonic sensors operate using ultrasonic sound. The sensor emits an ultrasonic chip, which is reflected off of and object. The sensor times how long it takes for the sensor to emit the chirp, and have it received off the object as an echo. Using the equation of the speed of sound in air, the sensor monitors distance. The sensor operates using a 40kHz chirp. This frequency falls in the sound range commonly used by animals for communication. Frequencies that are much higher, for example 1-20 mHz are used more commonly for medical imaging.... [tags: Various]

- Although cosmetics became widely popular in the 1900s, tombs from 3100 B.C. have revealed that makeup originated in the first Egyptian Dynasty ("The History of Makeup", 1). Researchers found that these cosmetics contained ingredients that ranged from lead to cat dung; both of which are toxic. The use of toxic chemicals in cosmetics, such as coal tar, negatively impacts a person's health. Cosmetic companies put consumers' health at risk due to the use of toxic chemicals, marketing ploys and failure to properly regulate their own products and the chemicals they contain....

- Qualitative Analysis Purpose: In this lab, we would tests the ions of Mg2+, Ca2+, Sr2+, and Ba2+, and enable each to be identified separately. And by using these observations, we could also identify an unknown. We also would tests the ions of SO42-, CO32-, Cl-, and I-, that also enable each to be identified separately, and to be use to identify the unknown. Safety: Chemicals include toxic. Remember to wash hands after the experiment. Procedure Summary; Part I - Qualitative Analysis of Group 2 Elements We first mix 0.02M K2CrO4 with each Mg(NO3)2, Ca(NO3)2, Sr(NO3)2 and Ba(NO3)2 together.... [tags: Chemistry Lab]

- William Stern in the 1912 took the mental age of an individual, divided it by the chronological age and obtained the ratio, which he called as an intelligence quotient. Intelligence quotient (IQ) is a score used to express the relative intelligence of a person. In the modern society with high competition in different areas intelligence tests are widely used. IQ tests starting to appear in job interviews as a part of the application process as well. This is still a controversial issue about whether IQ tests should be included in the employability process.... [tags: Tests, Jobs, Skills]

- Manmade harmful chemicals Many people are unaware and simply misinformed of the major implications that many chemicals that are manmade can have on their bodies. Several things I want to discuss are as follows. Hazards of using most pesticides, the affect it can have on pregnant women, cancer risks among painters, how children are affected from many chemicals, and also perfumes that manwomen use and how it has been linked to certain types of cancer. One would really believe that with all the current technologies these days there would be a lot less of these harmful chemicals in our air, and products that most humans use every day....

- According to Peter’s map – the north is rich and the south is poor, this is also stated by the Brandt Report. The Brandt Report works on the principle that; if you give a man a fish, you feed him for a day but if you teach him to fish, you will feed him for life. This basically means that if you give someone in a poor country some fish for example, it will only last for a limited amount of time, because it gets eaten – a short term solution. Whereas if you teach him how to fish, he can go and fish for himself and feed himself free of charge to him or anyone else – a long term solution.... [tags: Various]

FIZZES GIVES OF BUBBLES
NO FIZZ BUT PECEPITATE
PECEPITATE AND FIZZES
After all the chemical experiments I found out which chemicals fizzes
and precipitate when it is mixed with other chemicals as l have shown
above in the table. As you see above that when nitric acid is mixed
with calcium carbonate it fizzes so as lead carbonate and when mixed
with hydrochloric acid it fizzes as well because it has carbonate
material that makes it fizz. Where as some the material are not
fizzing when they mixed with the acid because they don’t get those
chemicals, which make them fizz.
