The boiling points of alkanes increases with increasing number of carbons. This is because the intermolecular attractive forces, although individually weak, become cumulatively more significant as the number of atoms and electrons in the molecule increases.
So therefore your answer choice will increase. (B)
Make sure there are the same number of atoms of each element on either side.
1) Check each one.
2) If one's out of balance, alter the equation to balance it and go back to 1)
3) When everything's balanced, you're finished!
We have 1 Na on the left and 2 Na on the right here. We'll need another NaOH to balance it:
2 NaOH + H₂SO₄ > Na₂SO₄ + H₂O
Now O is out of balance. There's 6 on the left and 5 on the right. We'll need more H₂O:
2 NaOH + H₂SO₄ > Na₂SO₄ + 2 H₂O
Fortunately H is in balance. S is also in balance here, so looks like we did it!
Need any more help?
Contains only Carbon and Hydrogen.
(3) CH3CH3
Here you are! I hope it helps, and also for the ones I put a red ‘x’ it depends on how you round it.
For this case, we have that by definition:
<em>Manganese is a chemical element that has an atomic number equal to 25. This element is located in group 7 of the periodic table of the elements. The symbol for this element in the periodic table is: Mn.
</em>
Therefore, taking the square root we have:
Answer:
the square root of the atomic number for manganese is 5.
