Answer:

b. Fe-O

Explanation:

A way to predict melting points for ionic compounds is with electronegativity.

Electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

The most electronegativity difference (E.D.), the highest melting point, thus:

E.D. Al-N = 3,0 - 1,6 = <em>1,4</em>

E.D. Fe-O = 3,5 - 1,8 = <em>1,7</em>

E.D. W-C = 2,5 - 1,7 = <em>0,8</em>

The most electronegativity difference is from Fe-O, thus, this ionic compound will have the highest melting point.

I hope it helps!

8. The time period of artificial satellite in a circular orbit of radius R is T. The radius of the orbit in which time period is

Elena-2011 [213]

Explanation:

It is given that,

The time period of artificial satellite in a circular orbit of radius R is T. The relation between the time period and the radius is given by :

$T^2\propto R^3$

The radius of the orbit in which time period is 8T is R'. So, the relation is given by :

$(\dfrac{T}{T'})^2=(\dfrac{R}{R'})^3$

$(\dfrac{T}{8T})^2=(\dfrac{R}{R'})^3$

$\dfrac{1}{64}=(\dfrac{R}{R'})^3$

$R'=4\times R$

So, the radius of the orbit in which time period is 8T is 4R. Hence, this is the required solution.

valkas [14]

Answer:

<h3>The answer is 122.5 g</h3>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume = 7 mL

density = 17.5 g/mL

We have

mass = 17.5 × 7

We have the final answer as
