magnesium looks like gold bars but it is grayish sliver
Yes, Clostridium butyricum is a Gram-positive bacterium.
Quicklime is white and can be crushed into a powder or appear as stones
It doesn't look like anything...you can't see it.
Gram-positive cocci are bacteria with a spherical shape that retain a purple stain in the Gram staining method, indicating a thick peptidoglycan cell wall. Gram-negative rods are bacteria with a rod shape that appear pink after Gram staining due to their thinner peptidoglycan cell wall and an outer membrane containing lipopolysaccharides. Additionally, gram-negative rods generally have higher resistance to antibiotics compared to gram-positive cocci.
magnesium look like white powder after burning in air. magnesium burns in air n react with atmospheric oxygen n forms magnesium oxide which is a white powder.

A gram is a measure of mass - it does not "look" like anything.
Magnesium burns with an intensely bright white light and forms magnesium oxide. Magnesium oxide is a white solid, often a powder. Do not look directly at burning magnesium - it may damage your eyes.
As used here, grain is a measure of weight- ABOUT 1 gram. Smokeless gun powder is usually grey to dark grey, and may consist of tiny flakes, disks or rods.
.25 grams of meth is equivalent to about the size of a matchstick head or a small crystal. It can vary in appearance depending on its form (crystal, powder, or rock) and purity.
Gram is a solid measurement. Air is not solid.
It has a big Baking Powder label on it
One one-thousandth of a gram looks like mg, or milligram.
It depends upon the chemical, substance, or element the material is made of, but it is a given by you that it will be a weight of 1 g. If you could specify the material a better description could be given.
0.5 g
It makes a white light which you aren't aloud to look at because it will hurt your eyes.Above is correct. Magnesium and oxygen can burn explosively, producing a LOT of heat, intense light, and magnesium oxide.
