<span>A compound which is called ionic compound dissociates
into ions when in aqueous solution. These ions move freely in the solution and
can allow the flow of electricity into the solution. These ions contains a certain charge or what is called the oxidation number.</span>
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
Answer:
H+(aq) + OH-(aq) ⟶H2O(l)
Explanation:
Step 1: The balanced equation
HCN(aq) + KOH(aq) ⟶ H2O (l) + KCN (aq)
H+(aq) + CN-(aq) + K+(aq) + OH-(aq) ⟶H2O(l) + K+(aq) + CN-(aq)
Step 2: The net ionic equation
The net ionic equation, for which spectator ions are omitted - remember that spectator ions are those ions located on both sides of the equation - will , after canceling those spectator ions in both side, look like this:
H+(aq) + OH-(aq) ⟶H2O(l)
As you move from left to right across a period, the number of protons in the nucleus increases. The electrons are thus attracted to the nucleus more<span> strongly, and the atomic radius is </span><span>smaller</span>
