There are 1.51x10^24 atomsU in 2.50 mol of Uranium.
This is because a mole consists of 6.02x10^24 atoms. SO with this info,
2.5 x 6.02 x 10 = 1.505 x 10^24
but because we must round, the answer is 1.51 x 10^24

XD silliness aside, I hope this helped!
Answer:
mineral acids are obtained from one or more inorganic compounds which is a compound that lacks carbon and hydrogen bonds. Inorganic compound examples include water and carbon dioxide. Something all mineral acids do is form hydrogen ions and the joined together bases when it is dissolved in water.
Explanation:
Answer:
it gains 2 electrons
Explanation:
atoms want to be more stable, for oxygen it's number is 8, 2 less than the stable ring of 10. and hydrogen has a single electron, 1 less than the stable ring of 2. so oxygen takes 2 electrons 2 make it stable and hydrogen becomes attatched to the oxygen atom to form a covalent bond
The answer is highly soluble
<h3>How does sodium hydroxide dissolve in water?</h3>
When hydroxide (NaOH) dissolved in water, it divides into positively and negatively charged sodium ions (cations) and hydroxide ions (anions). These ions move freely and independently in water, while cations prefer to be surrounded more closely by anions and vice versa.
Although sodium hydroxide is more soluble in hot than in cold water, the process of dissolving sodium hydroxide in water is exothermic.
The unknown compound's insolubility in water might be attributed to its big hydrocarbon group. Because it is dissolved in 5% Naoh, its substituent may be acidic because the interaction with NaOH produces an anion that is soluble in aqueous solution.

The molarity of the acid is 1.25 M.
<u>Explanation:</u>
We have to find the molarity of HCl by writing the balanced equation that is the neutralization reaction of Hydrochloric acid with the base, Sodium Hydroxide, NaOH.
HCl + NaOH → NaCl + H₂O
From the balanced equation, we can find that one mole of an acid is used to neutralize one mole of a base.
As per the law of volumetric analysis, we can write the equation as,
V1M1 = V2M2
Here V1 and M1 being the volume and molarity of the NaOH
V2 and M2 being the volume and molarity of HCl
V1 = 250 ml
M1 = 0.50 M
V2 = 100 ml
M2 = ?
Now the above equation can be rearranged to find the molarity of the acid as,
M2 = 
= 
= 1.25 M
So the molarity of the acid is 1.25 M.
