Canary
the different gases you can test for are a solid and liquid
Miners used canaries in cages to detect hazardous atmospheres in the mines because canaries are more sensitive to mining gasses than people are. If the canary collapsed, that meant that there were poisonous gasses in the tunnel, and the miners would evacuate until the mine had been ventilated and was safe again.
You can approach your parents by expressing your curiosity about your intellectual abilities and why you believe taking an IQ test would be beneficial. It's important to have an open and honest conversation with them about your interest in taking the test and to listen to their perspective on the matter.
Yes
No. This test is safe during pregnancy.
You can test the evolved gases in electrolysis of water by collecting the gases separately in test tubes placed over the anode and cathode. The gas collected at the anode is likely oxygen, while the gas collected at the cathode is likely hydrogen. You can confirm their identities by performing simple tests such as the re-ignition test for oxygen and the "pop" test for hydrogen.
Yes, farts are flammable because they contain methane and hydrogen gases, which can ignite in the presence of a flame. However, caution should be used when attempting to test this as it can be dangerous.
they will test if there are any new gases
No. pH is for aqeous solutions.
Lassaigne's test involves the use of concentrated sulfuric acid and heating, which can lead to potential chemical hazards such as acid burns, release of toxic gases, and potential fire hazards. Incorrect handling or insufficient precautions during the test can lead to serious accidents and injuries. It is important to conduct this test in a well-ventilated laboratory and to wear appropriate personal protective equipment.
