What type of experiments should be done in a fume hood?
Experiments with: - acids as liquids or gases - volatile solvents - corrosive materials - fine powders - materials with a very low radioactivity - toxic materials - reactions potentially explosive - sometimes, reactions involving thermally decomposition etc.
Can you melt powders into liquids?
Definitely. Powders are simply solids broken into smaller particles. As we know, melting is the phase change from the solid state to the liquid state. Thus, we can definitely melt powders.
Most oral powders for reconstitution are what?
Anitbiotics
Is zirconium poisonous?
The element is noted for its slight toxic ability and is poisonous to humans and anmimals. In a powder form the element is an extreme fire and explosive hazard; it may spontaniously combust at any givin time but is much more likely to explode in warmer tempratures.(note: this element will burn under water)
What materials are you allowed to use in crime busters for science olympiad?
You are allowed to bring one two-sided cheat sheet for each team, NOT for each team partner. You are also allowed to bring trays to place you powders and metals on. You are allowed to bring your own writing utensils. You are allowed to bring something to scoop the powders and metals and liquids out of their containers (such as popsicle sticks for powders and droppers for liquids). You are also allowed to bring a magnifying glass. That's about basically all you need. Oh wait, I forgot. These you MUST have. They come in very handy. Good luck! (I did this event this year, got 17th place :])

What are materials needed to make fingerprint powder?
The earliest fingerprint powders were made with lampblack (soot). There are now so many specialized powders and reagents used that the list would run for several pages.
What do flavor houses make?

Are dishwashers bad for the environment?
No, dishwashers are not bad for the environment. Most of the dishwashing powders and liquids are made with biodegradable materials that do not affect the ozone.
what is the independent variable and dependent variable for fingerprint identification?
The independent variable in this experiment is the fingerprinting powders. The dependent variable is the points of minutiae, which are identifying points on a fingerprint.
What can postal xrays see?
Postal X-Ray images are monochrome, with highlights for different density of materials. They are able to clearly view powders in envelopes.
What are the advantages of powders?
powders dissolve easier in liquids then solids

What powder do you use in your 3006 150 gr.ballistic silvertip ammo?
Whichever one gives the best results. You have to experiment with different powders. All weapons will exhibit a preference for different loads.
