For the First part I believe elements naturally exist in nature and compounds are formed so elements can be more stable. (I think this is right I’m not 100% but I’m close)
For the second part the two main types of bonds are ionic and covalent. Ionic bonds involve the transfer of electrons and covalent bonds involve the sharing of electrons. (I’m 100% on this one)
Answer:
i cant see the question i would if i could see it
Explanation:
<u>Answer:</u> The concentration of the solution is 0.25 M
<u>Explanation:</u>
Let the volume of solution of 2.5 M NaCl be 10 mL
We are given:
Dilution ratio = 1 : 10
So, the solution prepared will have a volume of =
To calculate the molarity of the diluted solution, we use the equation:
where,
are the molarity and volume of the concentrated NaCl solution
are the molarity and volume of diluted NaCl solution
We are given:
Putting values in above equation, we get:
Hence, the concentration of the solution is 0.25 M
Hello.
The answer is: Test
To test a hypothesis you test it with a test to prove if your correct or wrong.
