Answer:
c
Explanation:
the positive charges of the nuclear and the negative charges of delocalized electrons
<u>Answer:</u>
<em>Theoretical density values </em>
- brass-

- bronze-

- steel-

<u>Explanation:</u>
All of these substances are<em> </em>alloys (a substance made from melting two or more substances, one of them usually being a metal). Brass is a combination of copper and zinc, bronze is mostly copper, tin and other non-metals as well and steel is majorly made up of iron and copper. These alloys have various uses and varying importance in different kinds of industries.
Answer:
%Li-6 = 5.996% & %Li-7 = 94.004%
Explanation:
let X₁ = Li-6 & X₂ = Li-7 where Xₙ = mole fraction
X₁ + X₂ = 1 => X₁ = 1 - X₂
6·X₁ + 7·X₂ = 6.94004
=> 6(1 - X₂) + 7·X₂ = 6.94004
=> 6 - 6·X₂ + 7·X₂ = 6.94004
=> 6 + X₂ = 6.94004
X₂ = 6.94004 - 6 = 0.94004 => %X₂ = %Li-7 = 94.004%
X₁ = 1.00000 - 0.94004 = 0.05996 => %X₁ = %Li-6 = 5.996%
The answer is c because you said it was c lol
<span>Read the Fig 4 description. From there you can conclude that it does scatter light, because its ot a solution. So it must be a mixture, the substances are not dissolved so therfore they aren't a solution.</span>
