Chemistry

adell [148]2 years ago

Answer:

I had the same question and I put a total lunar eclipse.

Explanation:

A total lunar eclipse would be less widely visible because, in a partial lunar eclipse the moon only has to partly be in the Earth's shadow.

I don't know if this is helpful or not, but this is what I put if you still needed it.

Choose the selection which correctly characterizes all three of the following substances in terms of whether they are polar or n
ohaa [14]

Answer:

SiH4 is nonpolar and BBr3 is nonpolar and SiF4 is nonpolar.

Explanation:

SiH4 is a non-polar compound. Though the Si–H bonds are polar, as a result of different electronegativities of Si and H. However, as there are 4 electron repulsions around the central Si atom, the polar bonds are arranged symmetrically around the central atom having a tetrahedral shape hence they cancel out making the compound nonpolar.

SiF4 is a nonpolar molecule because the fluorine atoms are arranged symetrically around the central silicon atom in a tetrahedral molecule with all of the regions of negative charge cancelling each other out just like in SiH4.

The 3 bromine atoms all lie in the same plane thus the geometry of the compound will be trigonal planar. The BBr3 will be non polar because the three B-Br bonds will cancel out each others' dipole moment given that they are in the same plane.

ValentinkaMS [17]

Answer: Butane will effuse more quickly because it has a smaller molar mass

Explanation:

Molar mass of C4H10 = 58.123 g/mole

Molar mass of I2 = 253.808 g/mole

If I want to lower the volume (loudness) I can do which of the following. Select all that apply.
nirvana33 [79]

Sound travels in waves and the height of the wave is the loudness of the sound.

To decrease sound, you need to make the waves not so high, so you can

- decrease the amplitude

- decrease the height of the crest   (lower the top of the wave down)

- increase the height of the trough  (bring the bottom of the wave up)

It's all about getting the wave to be closer to the center, to not be so high and low, but to be flatter.
