Deposition is the correct answer if I believe so
Answer:
2) Add a solution of NaBr
Explanation:
Lead (II) bromide is an inorganic powdery substance that has a solubility in water of 0.973 g/100 mL at 20°C. It is insoluble in alcohol but is soluble in alkali, ammonia, NaBr, and KBr
PbBr₂ is slightly soluble in ammonia, and it reacts with NaOH to produce Pb(OH)₂ and NaBr
Therefore, the best solution for dissolving PbBr₂(s) is NaBr
Answer:
- The main idea behind MADs is that they use the principle that metallic objects (submarines) interfere in the magnetic lines of Earth forces. And this equipment detects this anomaly.
- Submarines can be detected by using MADs
- The history of MAD development
In 1917 the interest in the detection of submarines started with the study hydrophones. Then in 1918, the U.S. considered to use the magnetism in this area but it did not result to be practical as it had a limited detection range.
Then by 1941 in Britain and in U.S. developed magnetic detection devices to measure Earth’s magnetic field, so after that in 1943 MADs were installed in ASW aircrafts.
Due to the limited range and its lack of ability to detect the magnetic variance from different sources, MAD started to be used in combination with sonobuoys. This combination allowed an aircraft to localize submarines with the confirmation of sonobuoys.
Explanation:
MADs are Magnetic Anomaly Detectors. Their function is to detect anomaly in the Earth’s magnetic field caused by submarines.
Submarines are made of ferrous metal which contain domains that are tiny magnets form of iron molecules. This material creates a disturbance that can be detected in the magnetic field.
A chemical Property I hope this helps friend ^^
Answer:
Volume
Explanation:
A cubic centimeters(cm³) is a measure of volume that is equal to a cube with width, length and height are all 1 centimeters. then, multiply length, width and height values together, this will give you the volume of the cube. 1 inch = 2.54 centimeters
