I'm not quite sure but I think if you field the corner or cut it it would physically change it while not creating something new (chemical change).
A solution that has the capacity to hold additional solute at a certain temperature is called Under-saturated.
For a and b, you need to divide it by Avogadro’s number to find the answer.
a. (6.022x10^23)/6.022x10^23 = 1 mole of Ne
b. (3.011x10^23)/6.022x10^23 = 0.5 moles of Mg
For c and d, you’ll use the mass provided divided by the molar mass to find the number of moles.
Pb molar mass = 207.2 g/mol
c. (3.25x10^5)/207.2 = 1.57x10^3 moles of Pb
For d, I can’t tell if is Cu, C or something else but you can follow the steps above to solve the problem.
We can confirm that the diameter of the double helix structure of DNA stays the same because hydrogen bonding is always between the A and T bases and the G and C bases.
<h3>What are these bases in DNA?</h3>
The AGCT bases in DNA are the nucleotides that comprise it. These nucleotides include
- Adenine
- Cytosine
- Guanine
- Thymine
By always bonding adenines with thymine and Guanine with cytosines, the DNA strand maintains a constant diameter.
Therefore, we can confirm that the diameter of the double helix structure of DNA stays the same because hydrogen bonding is always between the A and T bases and the G and C bases.
