Answer:
100,000,000,000
Explanation:
Given that :
1 hubble space telescope pointed at 1 section of the sky reveals 10,000 distinct galaxies ;
Number of sections from which observation is to be made = 10,000,000
Number of distinct galaxy per section = 10,000
Number of galaxies that would exist in the known universe :
Total number of galaxies in the known universe :
Number of galaxies per section * number of sections
10,000 * 10,000,000
= 100,000,000,000s
It's ionic because electrictrons are only lost or gained in ionic bonds
