It is always half of what the o2 is
Explanation:
1.undetectable to electromagnetic waves
2.hiding an object from an illumination containing diffre t wave lengths become difficult as the object sizes grow.
3. reduce the scattering by two orders.
You can identify a substance, by testing the melting and boiling point and find a known substance that has the same melting and boiling points as the one tested
Answer: 204.2 g/mol
Explanation:
Elevation in boiling point is given by:

= Elevation in boiling point = 
= boiling point constant = 
m = molality

where,
n = moles of solute = 
= weight of solvent in g = 1g
Molality =
Putting in the values we get,


The molar mass of caryophyllene is 204.2 g/mol.
Answer:
The answer is 2Al + Pb(NO3)2 ->2AlNO3 + Pb.
Explanation:
Al represents <em>A</em><em>l</em><em>u</em><em>m</em><em>i</em><em>n</em><em>i</em><em>u</em><em>m</em><em> </em><em>.</em>
Pb(II) represents <em>L</em><em>e</em><em>a</em><em>d</em><em> </em><em>(</em><em>I</em><em>l</em><em>)</em><em> </em><em>i</em><em>o</em><em>n</em><em>s</em><em> </em><em>.</em>
NO3 represents<em> </em><em>N</em><em>i</em><em>t</em><em>r</em><em>a</em><em>t</em><em>e</em><em>s</em><em> </em><em>i</em><em>o</em><em>n</em><em>s</em><em> </em><em>.</em>
