the element copper cu has two naturally occurring isotopes. 69% of all coopers consist of atom with 34 neutrons, 31% of all samp
solniwko [45]
Answer : Average atomic weight of copper atoms will be 63.62 u. 

Explanation : For calculating average atomic weight for any given atom we use this formula,

m = Σm_{i} X % abundance

where, m - avg atomic mass of isotope.
and m_{i} - mass of isotope

on solving we get, 
m = [63 u X (69/100)] + [65 u X (31/100)] = 63.62 u.

Why can't we use chromatography paper to separate different colored pencils?
Sveta_85 [38]
Chromatography is a way of separating a mixture of chemicals which are in gas or liquid form.  when the paper absorbs the liquid, the different colours from the colouring pencils will not be separated because they are insoluble solid pieces,also because they are solid the colours will not be able to creep up the paper which is why chromatography can not be used to separate different coloured pencils.

As a real gas deviates from ideal gas behavior, the particles _____
Alik [6]

Answer:

Have some attraction towards each other

Explanation:

Gases deviate from the ideal gas behavior because their molecules have forces of attraction between them. At high pressure, the molecules of gases are very close to each other so the molecular interactions start operating and these molecules do not strike the walls of the container with full impact.

Hope this helps :-)

Is chlorine malleable or brittle?
Oksana_A [137]

Chlorine is not malleable or ductile. This is so because nonmetals, like chlorine, are brittle.

<h3>What is a chlorine physical characteristic?</h3>

The odor of chlorine is distinctively intrusive and upsetting. The liquid is pure amber, while the gas is a greenish yellow tint. The information on the physical characteristics of chlorine as discovered by various researchers reveals some variances.

<h3>What is brittle versus ductile or malleable?</h3>

In essence, metals that are malleable or ductile can both deform in some ways through plastic deformation in response to stress. Brittle metals are those that fracture without significant plastic deformation. Brittle is the antithesis of ductile and malleable in this context.
