O homo E hetero ore E qrtz O G E ed O dress E salt O rw O N2 O it's semantics but things like rainwater with stuff like CO2 in it -while there is different materials inside of it - at a microscopic scale it is same from place to place - homogeneous milk is chemcially heterogeneous as the fat globs have just be made smaller to be suspended. and homo just means same/hetero different - used a lot in science
For the best answers, search on this site shorturl.im/avGgJ gasoline - homogeneous muddy water - heterogeneous steel - homogeneous ink- homogeneous crude oil - heterogeneous bronze-homogeneous Hope this helps. :) -Violet
I strongly disapprove of the words homogeneous and heterogeneous, it just wreaks of sexuality in the classroom. Same or mixed would be preferable. Iron ore can be a combination of haematite and limonite, Fe2O3, Fe3O4 and just plain FeO. Chemically, we have a combination of different elements in varying amounts. It must be classified as hetero. Quartz, too, is a molecule composed of two different elements, silicon and oxygen, SiO2. All quartz is SiO2 apart from natural and unnoticeable impurities such as Al and Fe, but we will call it homo. Granite is an igneous rock composed of quartz, feldspar, biotite so, being a mix, we will call it hetero. Energy drink is a mix of water, presumably caffeine, prhaps vitamins and carbon dioxide. It's a mix, too, so hetero. Salad dressing. It's a mix of the items you list, so, hetero too. Salt, NaCl, is a mineral with a regular chemical formula, so we will call it homo. Rainwater is H20 which will have dissoved some CO2 and NO2 during its fall, which converts it into a very weak acid but still one capable over time of carving out massive cave systems in limestone country. the nitrogen is a valuable resource delivered to plant systems. Rainwater has to be hetero. Nitrogen is a single element only. Hence, it is homo.
The magnetism depends on the alignment of 'natural' magnets inside the magnet. Due to physical shock, thermal shock, external magnetic fields some of these magents re-align over time. So, yes, the power decreases.
