The new combination is called a mixture.
In mixtures, since the substances are not chemically combined together, they still remain their own physical and chemical properties, and can be separated by simple physical methods such as filtration or distillation.
On the other hand, if the two or more substances are combined where they get new properties, the new combination will be called a compound. They cannot be separated by physical methods, but chemical methods such as heating or electrolysis.
The number of Ml of a 0.40 %w/v solution of ,nalorphine that must be injected to obtain a dose of 1.5 mg is calculated as below
since M/v% is mass of solute in grams per 100 ml
convert Mg to g
1 g = 1000 mg what about 1.5 mg =? grams
= 1.5 /1000 = 0.0015 grams
volume is therefore = 100 ( mass/ M/v%)
= 100 x( 0.0015/ 0.4) = 0.375 ML
Living: biotic
Non-loving: abiotic
The answer is False. Absorption is the process or action by which one thing absorbs or is absorbed by another.
Iodine is a group 7A element. The halogens form anions because of their high electronegativities, so Iodine is unlikely to form a cation.
