The compound gallium phosphide () is a compound semiconductor having mixed ionic and covalent bonding. The electronegativities f

9966 [12]

Answer:

$0.08875$

Explanation:

Hello,

In this case, the first step is to compute the difference in the electronegativity for the formed bond between gallium and phosphorous by:

$\Delta E=2.1-1.6\\\\\Delta E=0.5$

Thus, we can compute the percentage of ionic character by:

$\%\ ionic\ character=16\Delta E +3.5 (\Delta E)^2\\\\\%\ ionic\ character=16*0.5+3.5*0.5^2\\\\\%\ ionic\ character=8.875\%$

So the fraction is just:

$\frac{8.875}{100}=0.08875$

Which has sense since gallium phosphide is a non-polar compound.

Regards.

a 15.0 kg chunk of ice falls off the top of an iceberg if the chunk of ice Falls 8.00 to the surface of the water what is the ki

kvv77 [185]

When we can get the Kinetic energy from this formula KE= 1/2 M V^2and we can get the potential energy from this formula PE = M g H
we can set that the kinetic energy at the bottom of the fall equals the potential energy at the top so, KE = PE
1/2 MV^2 = M g H
1/2 V^2 = g H
when V is the velocity, g is an acceleration of gravitational force (9.8 m^2/s) and H is the height of the fall (8 m).
∴ v^2 = 2 * 9.8 * 8 = 156.8
∴ v= √156.8 = 12.5 m/s
