<span>There's a trend in electronegativity. The bottom left of periodic table is the lowest (0.7) and the upper right is the highest (4.0). The most polar is the greatest difference in electronegavity.
hbr- 1~ , hi- 0.5~ ,hcl - 1.3~ , hf-1.8 so,hf is the answer</span>
Answer:
6.0 x 10 to the power of 23
The correct answer is the gamma ray. It has the most penetration power and will pass through a number of things. Also, a gamma ray has shorter wavelength therefore higher energy from the equation, Energy = hc/wavelength.
Because many animals are likely to die from contamination
Decreasing the volume increases the pressure, therefore due to Le Chatelier's principle, we can see that more HI2 will be formed as 2 molecules combine into 1 and that conserves space which in turn lowers the pressure.
