Do constellations appear the same in Northern and Southern Hemisphere? Why or Why Not?

Mashcka [7]

The visible constellations are definitely different between the Northern and Southern Hemispheres. In general, at any given point on Earth, only around 50% of the sky will be visible. We can understand this by considering the atmosphere as a sphere around the earth. The sky any person can view at one point can be compared to a giant dome equal to half of the sphere. And because the Earth rotates, the dome we can see changes, unless one is sitting directly on the North or South Pole.

A binary ionic compound is known to contain a cation with 51 protons and 48 electrons. The anion contains one-third the number o

7nadin3 [17]

Answer:

$SbCl_3$

Explanation:

The cation contains 51 protons and 48 electrons. The electrons are only lost not protons, so the element which corresponds to atomic number 51 is the cation which is Antimony (Sb).

Also, the charge on the cation is 51 - 48 = 3

This is because neutral atom contains the same number of electrons as protons.

Given the anion has one-third protons as cation which means thta:

Number of protons in anion = $\frac {51}{3}=17$

This corresponds to chlorine atom. The electrons are 1 greater than protons means that it has gain 1 electron.

So,

Sb Cl

3 1

Cross multiply the valency.

So, formula is $SbCl_3$
