Answer:
Diluted concentration is 0.5M
Explanation:
Let's solve this with rules of three, although there is a formula to see it easier
In 1000 mL (1L), we have 2 moles of NaOH
In 250 mL we must have (250 . 2) / 1000 = 0.5 moles of NaOH
These moles will be also in 1 L of the final volume of the diluted solution
More easy:
1 L of solution has 0.5 moles of NaOH
Then, molarity is 0.5 M
The formula is: Concentrated M . Conc. volume = Diluted M . Diluted volume
2 M . 0.250L = 1L . Diluted M
0.5M = Diluted M
Answer: I italicize for checking
- <em>Rocks are preserved through the process.</em>
- <em>Rocks change from one type to another.</em>
- <em>Different rock groups are interrelated.</em>
- Rocks change from one type to another in a specific order.
- <em>Environmental conditions influence a change in rock type.</em>
Explanation:
Rocks are preserved, as in you can't destroy them completely, but no, they don't <em>stay </em>the same they change.
