KCl : K+ as cation and Cl- as anion
Answer:
2
Step-by-step explanation:
The formula for the most stable form of oxygen is O₂, so the subscript is 2.
However, there is a less stable form of oxygen called <em>ozon</em>e. Its formula is O₃, so the subscript for ozone is 3.
The temperature will be the average of 10 C and 20 C which is 15 C.
Energy is transferred from faster moving molecules to slower moving molecules, and the result is the average of 15°C. <span>This is just another temperature problem where you add something hot to a cold liquid and you have to calculate the final temperature. Since the energy given up by the hot coffee = energy absorbed by the cold coffee, the mass of the two fluids is the same (each is 1 cup) and both are coffee so the specific heat is the same, you get T hot - Tfinal = Tfinal - Tcold and then you solve it, you get T final = (T hot + Tcold) / 2 which is simply the average of the hot and cold temperatures.

1) use the formula PV=nRT
2) Plug in given values: P(8.77 L)= (1.45 mol)(0.0821)(293 K)
3) isolate P: P= (1.45x.0821x293)/(8.77)
4) solve: P=3.98 atm
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.
