are the following physical or chemical changes1. forming a bar of copper into a wire2. transferring graphite from a pencil to paper when writing3. dissolving a drink mix in water4. a puddle drying up after rain5. dew on a winshield changes to frost6. magnesuim metal burns and becomes white powder7. a pine log is cut into boards8. apple cider becomes vinegar1. what physical property could you use to seperate sand and sugar? how would you do it?2. use the law of conservation of mass to explain why a rusty nail weighs more than the original nail.
1. forming a bar of copper into a wire CHEMICAL 2. transferring graphite from a pencil to paper when writing PHYSICAL 3. dissolving a drink mix in water PHYSICAL 4. a puddle drying up after rain PHYSICAL 5. dew on a winshield changes to frost PHYISCAL 6. magnesuim metal burns and becomes white powder CHEMICAL 7. a pine log is cut into boards PHYSICAL 8. apple cider becomes vinegar CHEMICAL (I THINK) 1. what physical property could you use to seperate sand and sugar? how would you do it? umm i dont know if this answers it, but filteration seperates 2. use the law of conservation of mass to explain why a rusty nail weighs more than the original nail. because a chemical change occured and the rust built up and more mass was added. (i dont think that answer used the law though)
yes go to a vet ask about caring about they may give you special items for like feeding it(remmember your saving a life)
i see. so you will be acting like a mother cat now. first, always keep the kitten in a warm place. if you have an empty shoe box, put a clean cloth (old shirt) and put the kitten. this will be his/her crib. then use a droplet to feed him/her a milk. use warm water and any powder milk will do. no need special treatment on kitten. as long he/she in good hands, kitten will always be fine. just remember feed him with milk if you think he/she wasn't able to eat food. hope this helps. goodluck on your kittensitting.
I would say it's too little information to tell. If you mix red paint and yellow paint.you get orange paint. But this isnt a chemical change, it's physical. However that doesn't mean that a red compound won't react with a yellow compound to produce an orange one.
A physical change is a change in size, shape, state or solution. A chemical change produces a new material. You tell it by a color change, odor change, great change in energy, precipitate or gas formed. 1. P 2. P 3. P 4. P 5. P 6. C 7. P 8. C they have different solubilities The iron of the nail combines with the oxygen to form rust
