List 2 extensive properties and 3 intensive properties of a 5.0g, 1 cm3 cube of silver
jeka57 [31]

Properties of matter can be broadly classified into two categories:

Physical properties which usually involve a change in the state of matter and Chemical properties which involve a change in the chemical composition of matter.

Now, physical properties can be further classified as:

Extensive: these depend on the amount of the substance, eg: mass, volume  

Intensive: these do not depend on the amount of the substance eg: density, color, melting point, boiling point

Here we are given a 5.0 g and 1 cm3 silver cube :

Therefore:

Extensive properties are-

1) Mass of silver = 5.0 g

2) Volume of silver = 1 cm3

Intensive properties are:

1) Density of silver = mass/volume = 5.0 g/ 1 cm3 = 5.0 g/cm3

2) Melting point of silver = 962 C

3) Color = white/gray

If the dosage for a medication is 225mg/lb, how many grams should a 25-lb child be given?
Oksanka [162]

Answer:

5.625 grams

Explanation:

Start your equation with what you have been given.  Place the units you need in your answer on the right side of the equal sign.

225mg

-----------   X  -----------   X ------------- =   ?   g

   lb

Now start to fill in your equation and use a conversions to get rid of the units you don't want.  Convert mg into grams first.  The child's weight (25 lb) is placed over 1 just to get the equation lined up properly so you can see how the units cancel out.

225 mg                 1 g                  25 lb            5.625 g

---------------   X   ---------------  X   -------------  =   ---------------

   lb                    1000 mg                 1                  1

The lb on the top and bottom cancel each other out and you are left with just grams.  Even though it is over one, that is the same at just 5.625 grams.
